  1. Ok so I know many corydoras lay eggs on glass and other people will probably use spawning mops so this won't be of use to many other than myself but might be interesting anyway! So recently I've observed a few interesting things with my panda corydoras in my community tank. There is always breeding activity going on and eggs being laid but no fry appearing without pulling the eggs. My pandas never lay eggs on the glass, they occasionally lay eggs on roots of pothos hanging in the tank but mostly they use the java moss. At one point I had a small tuft of black beard algae (like maybe less than an inch in diameter/length) right next to my java moss and one day I noticed eggs in it from the corydoras, more than I had ever seen in the java moss at one time and in a much smaller area (I found at least 6 eggs in that small tuft of BBA). Now I know most fish hate the taste of BBA so I assumed it was just because the taste protected the eggs from being eaten by the other fish or snails etc and that's why it appeared that way - a survivorship bias so to speak, rather than the corydoras specifically preferring it to the java moss. The small tuft died off after a little while and I've not had any since and haven't thought much on it. Then even more recently I had a but of a filamentous/blanket weed type algae bloom and I was being lax with removing it (my tanks are hardly designer aquascapes so I pretty much don't mind a bit of algae unless it seems to be causing problems with the plants) and there was a good bush of it going, maybe 6 inches long by a couple inches wide suspended across some plant leaves. One morning I turned the light on to discover it absolutely full of corydoras eggs, I think I counted at least 15 which is more than I've ever seen my cories lay at one time (I only have two females and four males). I have no idea if the 'spawning media' triggered more spawning than usual, or somehow protected the eggs from being eaten (not sure how as you can see right through it much easier than the java moss) or if it was simply a coincidence. So anyway my plan to experiment is to cultivate a bunch of blanket weed type algae in a spare tank, then DIY some sort of mop with it (I was thinking a small plastic Tupperware container full of the stuff) and put it in my community tank and see what happens. My hope is to find out if; a) the corydoras do actually prefer it as a spawning media and it wasn't just a fluke b) this 'media' is somehow useful in protecting the eggs from the rest of the community c) if having their preferred choice of spawning media actually encourages/triggers more spawning than would have occured otherwise (not sure how I will really determine this part) Any thoughts or tips/advice? Not sure how to contain the blanket weed in the container without restricting access but hopefully it will just sort of stay put.
  2. So last year during quarantine I decided to scratch the itch I've had for feeding live food to my fish, I bought everything I needed but work and life got stressful (2020 am I right?) and I didn't start things how I intended. I ended up with a pair of Apistogramma Cacautoides that decided their quarantine tank was good enough to breed in even with out caves or real hiding spots. I just filled it with plants. I decided since I've never raised fry before to give it a try. It was also my first time having Apistos so I was kinda hedging my bets that If mess up with the parents maybe some of the babies will make it. That ended up being a very good decision but I digress. Since I suddenly had fry I needed to be able to feed them. Luckily I already had the brine shrimp. I never did get around to getting the large Ziss hatchery that I wanted as it was sold out at the time and i also wasn't sure that was something I needed for a single tank just to occasionally provide live food to my fish. In the end I was more than tired of constantly having to hatch brine to feed the babies. I ended up looking up other alternatives and my research eventually lead me to daphnia. In fact when I learned that daphnia can be raised in the same water parameters as my aquarium and will last in the tank until eaten I was sold. On top of that they continuously breed so they do all the work for you. (assuming you don't suffer major crashes) they have a fairly good nutritional value as well. (not quite as high as newly hatched brine). And from the information i was able to find online, newly hatched daphnia are smaller than newly hatch baby brine shrimp. Making them just as suitable if not more-so as food for small fry. My only frustration was the brief learning curve and my initial two crashes. I'm now on my third attempt which seems to be off and running. And I've started feeding them to my community tank as well as using them to help the last of the apisto babies finish growing out before I move them to the community tank like their siblings. Shorter summary: For my particular use case, supplemental live food for a single tank and/or use in a quarantine/hospital/fry tank. Culturing daphnia seems to be easier than constantly restarting with my brine shrimp dish. ( i know it would possibly be easier with more common methods) Not that brine shrimp is difficult at all but assuming I can keep a culture going then there is no more work to do than on my main tank. Occasional water change/occasional siphoning of the daphnia and snail mulm. I'm curious to hear from others that have tried both live foods. Have you had success with culturing Daphnia? Do you prefer the ease and reliability of hatching bbs over the uncertain but continuous culturing of daphnia?
  3. Been trying to make cheap planted tubs for propagation and rooting trimmings. I have a dirted indoor 50 gallon rubbermaid pond and a dirted indoor 40 gallon tuff stuff for this purpose. Today I set up 2 more, two large concrete mixing tubs from Home Depot, 13$ each for the tubs,24 x 36 outer dimensions, 8 inches tall, 20.9 gallons when filled to the rim, I’m going to use this journal to document my progress. Dirted with a thin layer of miracle grow organic garden soil: used pea pebbles to cap (full bag for each): did 100% water change like 6 times on each: using a single 32 watt ge balanced spectrum grow light for each: No heaters, but I am going to get sponge filters for them. Had some Val runners I trimmed out of another tank, maybe 9 of them, planted them in one of the tubs:
  4. I live in Mexico, after new year my family and I went for an outdoor trail walk ideal activity now a days because of Covid-19. The walk was on a local creek that starts off from a natural underground spring. I didn't expect much since we live in a pretty dry area, most rivers and creeks are dry all year round and when there is creeks they are stationary and have no life other than basic frogs or insects. The creek was thin, shallow and slow moving mostly looked like any other creek I've seen, but Suddenly I spotted it, it almost looked like some algae, but it was a massive floater colony ( if you can call it that) The colors basic green and a hue of red - pink. Upon spotting them I realized this could be a much more special place than I originally thought, along the trail I kept an eye on the creek and that helped me spot movement in the water, there was fish! it was small and it was quick to hide. Before leaving I remembered the floaters and took a sample with my empty plastic water bottle to analyze through observation. Since I got the sample I've been taking pictures and I'm creating a log of photos and video with my camera. From the very first moments of observing it I noticed micro fauna in the water. 10 days have passed and I've noticed Miniature snails and a few fly or mosquito larvae, thus I decided to enclose it every night and whenever I'm not around to look at it, wouldn't want them to morph into mosquitos in my room. The following pictures are from my cellphone, I haven't gone through all the video and pictures in my camera(higher quality) though so I wont post that now. I'm jumping the gun sharing these since I tried really hard to get Cory's attention in today's live stream and was unsuccessful. Since I got them I've done heavy searching for this plant on the internet, and I cant find anything on it. Mind you all I have little to no experience with aquariums but I've been following the YouTube channel for a long time a little under a year and every video I get closer to actually going all out in on the hobby. I'm really interested in aqua scaping maybe its cause I'm an architect and I feel its almost like landscaping duh, lol. But in all reality I'm a noob at this, literally haven't had a fish since I was like 12, I'm 29 now. And because of the sudden discovery that I just couldn't ignore I jumped the gun took the sample and here I am 10 days later, when I really wasn't thinking about investing in a tank etc. until much further, when I know more and am 100% sure this hobby was for me. Luckily when I was a kid I had multiple bettas and I had 3 small spherical aquariums which are perfect for my tests. I used the smallest one I had, and plan on if possible to grow these plants and get enough for all three aquariums and eventually enough for a much larger aquarium in a not so far future. Anyways, I'm sorry for the super long text, I really wanted to fully explain the context of where, when, who and why I'm doing this. And my intent with this is to get help identifying the plant and whether its a good option for an aquarium with fish. And if indeed its an unknown then look for help from local biologist or investigate on how to adequately register and name it to be found online. So far in these 10 days I've seen massive root growth and expansion in the little aquarium which I could post in a follow up post. Enough delay here are the photos. The creek, thin, shallow and steady or still flow. The Floaters in their natural environment!!! Discovery for me at least. 🙂 Floaters close up in my small aquarium. (daytime, direct sunlight) At night with dim lighting the edge lights up almost looking phosphorescent! couldn't really capture what it looks like with my cellphone with that dim light. Upon realizing there was mosquito or fly larvae I enclosed it letting it breath when I'm there to check on it. Roots, most where anchored on to a twig. and the pretty much have only one root per petal, and I saw new root growth soon after setting it in my new container. I did notice root curling in the end, I cant tell if that's just a plant characteristic as in maybe used to anchor on to things as seen in the twig, or if it is the result of a certain deficiency in the water since I took the sample and added about an equal amount of drinking water( water bottle) to have the floaters float off the bottom since the container is much bigger than the small water bottle used to take the sample with. I used drinking water to prevent adding any untested unfiltered tap water which I have no idea of its ph etc ( city water). I hope I did the right thing. If yo are still here reading this, THANK YOU ❤️ I will try to keep up with this thread daily until I get the help I need, Happy New Year to all
  5. Planted Nano Pea Puffer Cube For the first time ever, I have a beautiful rimless all-in-one aquarium. Over the weekend, my partner and I picked up a Tideline AIO 11.3G, which is just under 14” cubed. Our eventual goal is to house a single pea puffer (and possibly some amano shrimp as cleanup crew). As a seasoned aquarist, I know this aquarium will take a while to establish before I can add our new tiny friend. In the mean time, I will be keeping a journal about its progress. Full disclosure, I did pretty much pull this entire post directly from my blog. I use the blog to share information with friends and family and document my journey, but it makes it rather easy when I can format it there and just paste everything over here to spark conversation. Hope you enjoy! 💚ALL PLANTS ARE FROM AQUARIUM CO-OP💚 The Process Substrate Egg crate structure with *Magic Mud™️ There are two additional layers of egg crate stacked in the back to create depth without using excess substrate. It also brings the nutrient layer up a bit so it’s easier for the plants in the back to reach. As you can see, there’s about 1/2” of space from the edge of the egg crate to the glass, allowing me to keep a clean edged look on this rimless tank. In the back, I have a total of 1.5” of nutrient-rich layer. This will help feed the Sagittaria subulata (dwarf sag), Ludwigia repens, and Helanthium tenellum (dwarf chain sword) without having to reach their roots through 4” of sand. Hardscape Initial substrate pour. Sand is Caribsea Super Naturals Torpedo Beach and accent gravel is Spectrastone shallow creek regular. Addition of hardscape. I am unsure what kind of wood this is, but it’s very splintery and the glue wasn’t holding very well. Instead, I chose to zip tie it temporarily to ensure it doesn’t disturb anything or shift when I filled the tank. The rocks are a grayish toned dragon stone. All hardscape and sand was acquired from Dallas North Aquarium, which is an excellent store and I do highly recommend them. Top-down view. As you can see, I chose a budget light, the Lominie Asta 20. I will write a full review once I have tested the light for a decent period of time, but so far I really like it. Planting Addition of Sagittaria subulata – contained in the back corner behind the hard scape. My hope is that the hardscape will keep it from taking over the tank. This stuff grows fast and I really don’t want to be yanking up runners every week. Cryptocoryne wendtii sp. pink flamingo in the front (I am so ridiculously excited about this plant, it’s so pretty!) and Ludwigia repens just behind. Althernanthera reineckii and Helanthium tenellum added, and some baby java ferns tucked into the holes in the rocks. We added some Anubias nana petite, some Bucephalandra sp. Green wavy, and shoved some moss (Christmas moss? Unknown sp) into the splintery bits of the driftwood. The zip tie is a bit unsightly, but I would much rather have an unsightly zip tie for a month than have my hard work ruined by a stubborn piece of wood. I squeezed an established sponge filter over the tank, filled it, and started up the filter! After about 10 hours, the water is tannic, but no longer super hazy. The filter pump is a little too aggressive for my liking, so I have one on order that’s a much slower 80gph instead of 150gph. A single pea puffer isn’t going to need that much crazy filtration, and quite honestly the poor thing would probably get blown around by the flow. I’ll reserve the pump that came with the tank for another project. Final thoughts This scape turned out pretty great, and I’m really enjoying staring at it, even without livestock. I uploaded a YouTube short of the “sparkle” that happens in this aquarium that photos just can’t accurately capture. You can find that video here if you’re curious. *Magic Mud™️ is a product of my own design that I am still working on perfecting. Its main components are organic worm castings and natural red clay. The egg crate is simply there to keep everything in place and to avoid having the soil slide down to the edges of the aquarium, giving it a nice clean look all the way around without sacrificing a nutrient-dense base layer.

  6. So I occasionally collect wild scuds after work. We have an old gravel mine in the back that only gets dredged every few years. Every spring and fall, the amphipods swim into the shallow temporary pools on the edge to catch the warm sunshine. I’ve grabbed them there in the past to feed to my loaches. So anyway I randomly decided to try to keep some alive this year and see if they would breed for me. They’re pretty big at over an inch long so the breeding size adults are mostly going to be fed to my dojo loaches, dollar sunfish and killifish. I’m hoping to be able to net out babies to feed out to all the other fish. Anyways, any tips on long term scud care? Picture shows the edge of the lake, how I caught them (paper cup and gallon ziplock) and what I ended up putting them in (old 5 gallon acrylic hex that hadn’t been used in 10 years). I tossed some water sprite and duck weed in the top. I don’t know if they’ll eat it or not.
  7. Hi all, so- Something that's fascinated me from the very start of my fish journey, is how aquarium plants can have immersed vs emmersed growth. I've successfully grown Pothos completely underwater, and before that, I attempted (but failed) to grow terrestrial moss underwater. I'm wondering if there's any techniques to identify which plants would do best submerged! I know that probably hardy plants that like a lot of water would be best candidates, and plants that can be found growing near water, and maaaaybe plants that grow via cuttings or runners? It would be a safe bet to check out what grows in the local ponds and rivers, but I'm Wary of taking anything from there, yknow? I don't want to get in trouble, after all. I'm also wondering, how would you help acclimate something TO being submerged?
  8. I started an accidental experiment by waiting too long to bring my tubs inside at the end of the summer. I ended up with a bunch of maple leaves in my tubs, covered in snails. I moved the tubs inside and dumped some leaves in each tub, but I had a bunch left. I put those in a bucket with a Co-Op Sponge filter to try to keep the snails alive, and see what would happen. I sampled some water a couple of weeks ago, and tested it last night: I decided to feed the test water to some houseplants.
  9. Hello all! I'm currently in a biology class and have the opportunity to conduct an independent research project or experiment for an assignment, it does NOT have to be complicated or extremely in depth. It can be on any biology related topic, so I'd love to do an experiment involving something aquarium fish/aquatic plant related. I thought it might be fun to see what kind of ideas for experiments some of you might have – I'm currently brainstorming and am allowed to ask for ideas, so hit me with your best shots! Examples: What is the best form of ammonia/waste to use to cycle an aquarium? Does the temperature of the water affect the basking frequency of aquatic turtles? How does gravel depth affect the growth of [some plant]? Basically, a question where I can isolate a variable and gauge the animal's/plant's response to changes in that variable. And also preferably something that won't take more than a month or two to gather data. Open to anything, let's see what you all got!
  10. On Thursday I bought three moss balls, and wanted to see if they'd survive an alum treatment for snails, etc. I was interested in @Irene's test using alum versus other methods for snail eradication. Using my phone camera I examined them for any obvious critters. I saw what appeared to be several single eggs and groups of very small eggs (too small for snail eggs IMO). I caught a glimpse of some wiggly worm in the water. I rinsed and squeezed out the moss balls gently in cool tap water, then put them back in their container where I had mixed a rounded 1/8 teaspoon of alum in one cup of dechlorinated water I examined them over the next few days. I discovered that the thing that looks like a single, whitish-transparent egg is actually some kind of plastic bead and there are still many in there, so I wonder if this is some kind of growing medium. I saw no sign of snails, eggs or worms. Today I rinsed and squeezed them out in cool tap water again, and refilled their container with dechlorinated water and a tiny bit of fertilizer (1 drop mixed w/a capful of water, then a couple drops of that mixture). So far they look just as robust as when I started. They're going in my new betta tank next week (plants from Coop arriving today!!!) and I'll update this thread only if they start to turn brown. Right now they get a little early sun and are near my other plants with an LED room light on for about 8-10 hours a day. I just noticed a dog hair in the water, lol. You can still see the tiny plastic beads.
  11. I was wondering if it's possible to crush 'crushed coral' into a powder to increase surface area when trying to raise KH? I've had crushed coral in my tanks for a bit now and I can't seem to get my KH higher than a 2. Has anyone tried to do this before and if so, what was the result? Also I assume that the dosing would be much smaller? I'd love to hear your thoughts on this, -BisScottie
  12. I ordered some new plants and suction cups from Aquarium Co-op. I really wanted to try monte carlo but was afraid my low light tank wouldn't be kind to it. So, I used the suction cups to stick it to the side of the tank near the light. When I start seeing some growth I'll remove it from this pot and replace the rock wool with some eco complete and maybe some root tabs. If anyone else has tried something similar I'd love to know how you did it and your results.
  13. I bought the LED grow lights for my outdoor garden seedlings. The lights came yesterday but my first seeds wont be here until Monday (or so.) I typically start my seeds under T-8 6500 K fluorescent bulbs, but I had an empty shelf on my plant starting stand and I found four of the LED red/blue grow lights with really good reviews at a pretty good price. Since I have the lights and lots of aquatic plants also, I've put a small dish under the lights and one of each of my common floaters in it to see how they do. The lights are horrible for fish watching, or plant watching for that matter, but we'll see how the floaters (red root floater, salvinia minima, dwarf water lettuce, and frogbit) do under it. It might help them grow faster than they already do. I definitely wouldn't recommend the lights for viewing plants/fish, but it could be a good way to multiply your plant stock.
  14. So, I have failed every time I've tried to grow any type of Anubias plant. They all get a white-clear jacket of yuck around the rhizome and die off completely within 10 days. And I do mean die, the entire plant - leaves, stems, rhizome, roots - all go to mush and disintegrate. So I'm experimenting with a A. Barter tissue culture to see if any of these baby plants can get a foot hold and live in my water. Fingers crossed 🤞🤞
  15. Before After This snail tank started out as a plant grow out tank that I put next to my indoor plants for an experiment. Next thing I knew there was a bunch of snails so it became a snail grow out. Let me know what you think and if you have any questions feel free to ask!
  16. I’ve wanted to hatch live baby brine for a while now, so that is my project for this holiday weekend. I wanted to use supplies on hand and only bought the eggs and salt. This old glass drink dispenser seemed perfect for a hatchery. I used a nail and hammer to perforate the metal lid, punched the hole out, then hammered the edges to smooth it out a bit. I added a little over 1.5 gallons warm tap water, 1/3 cup marine salt, and half a teaspoon of eggs. I installed the heater and air stone, then put the dispenser on a hot pad to help retain heat. Initial thoughts: The edges of the hole on the lid could be smoother, and I wonder if I should be covering it to help with heat. I am also concerned there is not enough air; it’s sharing a USB nano air pump with the tank to the left. I do have an extra pump, but I’ll wait and see what things look like tomorrow. 😛
  17. I am curious if anyone has done any level of experimentation with changing their water temps to enjoy other aspects of their lovely fish. My thoughts come from my other hobby where I can see patterns in activity when certain water temps are present and how it plays a key role in activating instincts/actions. For more context, I know of the northern zone of the U.S. that in the spring when water temps raise to a certain level, that different species will be going into a more active feeding state that also pushes schooling activities and then on to spawn. Continuing on, the temp gets to a certain level the schooling can stop and put them into certain zones like grass or rocky areas. Cooling the water, they tend to slow down feeding and schooling activities aren't as pronounced. Just thinking through the ability to provide more thriving opportunities for our hobby and maybe this could be another avenue... Thoughts?
  18. I had asked earlier this year on this form whether or not anybody thought a geranium would be able to work in an aquarium so I decided to test it out and I've had great success my geranium in my tank has started flowering I think I'm going to continue and spread it or get different colors only issue cuz every once in awhile about once a week I wake up to find it sitting all the way into the water assuming my Oscar pleco or manganese have knocked it in very happy with how it turned out
  19. my 90g is a somewhat high tech set up with co2, lots of ferts and medium-high light. i have noticed over the past few months that the substrate i used (safe-t-sorb) is absorbing too much. it works similar to eco-complete in my experience but my ph/gh/kh is lowering, which is natural with co2 and this substrate, but i want to raise it. i decided to run a little experiment and, hopefully, not kill all of my plants. i picked up this bag of reef salt: it is high in calcium, magnesium, and other good minerals. i would just use crushed coral but i want to see if i can use salt in a planted aquarium to benefit my goldfish. one of my goldies ripped his tail on some driftwood (i did some rescaping and hopefully fixed the issue) and i want some salt in the water to help him a little. plus who doesn’t love running experiments. tank: 90g dosage: 30%, i decided to start off light and work my way up slowly. this bag treats 10g up to a salinity of 1.021 which is way way too high. i decided to dose it like regular aquarium salt with 1 tablespoon per 5 gallons. i dosed for 30 gallons to start off with. it has only been 2 days so too soon to tell but my plants didn’t keel over overnight lol. ill keep this dose for the next week and add another 3 tablespoons. ill just keep repeating this weekly till i start seeing some negative effects on plants. photos arthur with his ripped fin, some stress veins around the area of course but overall not looking too bad all my vals are looking healthy i was concerned about my emersed plants but the pothos is springing a new leaf today and the monstera is still fine. usually you see negative effects pretty quickly with houseplants and salt. new monstera leaf uncurling, on sunday it was still tightly wound so the salt hasn’t had any immediate negative effects. also as a small sidenote, the roots outgrew the diy pot so i just removed it. these are mostly peace lily roots with some pothos thrown in. they’re still holding on to a lot of eco-complete, i didnt bother removing the plants to rinse them. now i know this is a low dosage to start out with but i didn’t want to just bomb my tank from the start with how much work i put in. ill keep this thread updated as i raise the dosage and the effect it is having on the plants. anyone have any experience with marine/reef salt and plants they’d like to share?
  20. last saturday i redid a tank that had leaches that came in on some plants. ive had 2 of them sitting in a tub of water straight from the tap (no dechlorinator). our water is very hard and mineral rich here so i wanted to see what effects this would have on the leaches. its now thursday and they are still going strong. not sure what this proves besides them being unnecessarily hardy but i’ll see how long it takes for them to finally kick the dust. there are some pond snails in the tub that are still going strong too which is interesting.
  21. Extending the USB Nano Pump: Solar Power As my second test for the Aquarium Co-Op USB Nano Air pump, I have decided to start writing before the test is done, and to kick things off today. I'm hoping a few tests will come of this, but an "instant fail" is just as valuable. I'm hoping what may come of this will be some numbers (mAh in, hours per day, etc.) that can be used in later selections of solar powered batteries for this pump. I hope to answer this question: Is there a low-cost solar-powered battery by which I can run the USB nano pump indefinitely? Failure is defined as the power running out or the battery otherwise failing by other means. SELECTING THE SOLAR-POWERED BACKUP BATTERY In making my choice of backup battery, I listed the following criteria that needed to be satisfied: 1. It has to be water-resistant. 2. It has to be reasonably sized (not too large). 3. It has to be affordable. Not too much. The whole trick was to find something that is a balance between power and price. I settled on this IEsafy Solar Charger 26800mAh, Outdoor Solar Power Bank with 4 Foldable Solar Panels and 2 High-Speed Charging Ports for Smartphones, Tablets, Samsung, iPhone, etc, with Waterproof LED Flashlight from Amazon: https://www.amazon.com/gp/product/B08611FQKT (non-affiliate link) It cost $27.50 when I bought it last week, but seems to have risen to $40. A quick search of Amazon and the internet suggests that if you're resourceful, you can find one in the $30 range with these specs. But I still don't yet know if these specs are sufficient. A WORD ABOUT LOCATION AND TIME OF YEAR This test is going to be a bit less useful around the world; access to sunlight matters a lot. I live in north San Diego county, California, and it is currently July (middle of summer). It stands to reason that if I pick my spot correctly, I will get direct sunlight for much of the day. If I can figure out how many hours of direct sunlight I'll need each day, in theory I can move the charger around as needed. But in winter months and in locations farther from the equator, this may be more difficult. THE SETUP THE FIRST THING I DID WAS CHARGE THE BACKUP BATTERY BY PLUGGING IT IN. This has to be done first before expecting to make use of solar power at all. It took several hours to charge fully. I am combining this test with another project: A small daphnia culture in a 17-gallon tub. These tubs are $5 at Walmart, so there's no excuse not to have several! I filled the tub with well-used greenish water from my small pond, added extra mulm for good measure, dropped in a medium sponge filter from Aquarium Co-Op, and connected it to the USB nano pump. The pump is hanging from a hole I drilled in the lip of the tub. Then I connected the pump's power cable to the backup battery, which I placed on an empty Amazon box. I placed this entire rig in a spot where I expect it to get much sunlight all day. (I know that the sponge filter is not necessary daphnia, and many folks keep daphnia in still water even. But I HATE mosquitoes and want to stabilize things as much as possible. Also, I won't be ordering daphnia for several weeks, as I want the water to get much greener from the direct sunlight; I'll be feeding it a steady diet of grass clippings as needed.) TEST ONE: IS THIS REMOTELY VIABLE AT ALL? Today is lightly cloudy, but the clouds are seeming to burn off. The sun hit the charger at 9am this morning, so we are off and running! UPDATE 7/20/2020: This test has been canceled, for reasons outlined below. New test coming soon! Bill
