About Me

  1. Hello, I am experiencing green water in my tank for the first time in many many years. Its a planted tank and had been running just fine for a long time. The green water started like 2 weeks ago after a period of medicating and gravel vac-ing (something I usually never do), so I feel like the cause of this is not an excess of nutrients since I was feeding very lightly or not at all. So no feeding for a week until today and the 2 weeks before that the feeding was very light compared to the usual. Clearly there is some imbalance causing this, but what I'm wondering is, if I go back to treating everything in the usual way regarding feeding and cleaning, shouldn't the balance re-establish slowly? Or any other suggestions? Keep in mind I am not in a hurry at all to get rid of this green water, I just want the end result to be clear water and would like to achieve it in the most natural way possible.
  2. Having trouble with "green water algae". I purchased a device to kill the algae which worked fine; except it keeps coming back. I have emptied my tank and cleaned everything and even tossed the media in my box filter to no avail. Must I clean everything with bleach or something in order to keep this from coming back? I have cured one tank of this by doing the same thing I have done with, but have not been able to cure this tank. Thanks for your help!
  3. I have a 20 gallon, about 1/2 full of healthy hornwort to combat and prevent green water. But I currently have green water. Been 2 weeks. I'm keeping the light off for now, except a couple hours of very dim per day to help the fish find their food. I've decreased the adult's feeding from 2x to 1x per day, though I shouldn't fast them since about half are preggy, and I can't reduce the feeding for the tiniest fry. The tank is bare-bottom, with a ton of MTS, so no food is getting lost. (I also watch to make sure the filter doesn't grab it.) In the next few days, I'll put a few of my extra neocaridina in there, since they'll help re-process the MTS poo. My current question: Nitrate is ~5. Do I add Easy Green to help the hornwort, or leave nitrates low to starve the green water?
  4. The water was so green I couldn’t even see my fish. I would definitely vouch for GKM. I have since turned it off to let some algae grow on the glass of the tank for my bristle nose.
  5. I have a small vase that I was keeping in the bathroom window. It has a good population of micro worms and micro crustaceans, which I'd like to dump into tank(s) with fish. The catch is that the water is pea green, and I can't simply pour out the water and keep the critters, since the crustaceans stay in the water column. Pros and cons of emptying the critters and green water into a tank? Or maybe splitting it between multiple tanks?
  6. What would cause green water? Not cloudy, fairly clear but still having a green tint. This is a deep substrate, dirted tank.
  7. My 5 gallon planted shrimp tank has broken out with green water. My parameters are consistent nitrate- 10-20 nitrite 0 ammonia 0 gh 300 kh 80 ph 6.8 I am running a finnex stingray 8 hours a day I was running it 10 hours then dropped it to 8 once the green water showed up which seemed to make it worse. For filtration I run a aco sponge filter. I do around 2 pumps of easy green a week to keep my nitrates around 20 ppm. I am also injecting co2 and my drop checker is a lime green after 2 hours of light and stays like green till it turns off. In the tank I have 3 Amano shrimp and 10 red rilis and a collection of pond snails. I started 2 months ago and the green water showed up about a week and a half ago. I know that my best option would be to get a uv sterilizer but I haven’t been able to find anything that isn’t just overkill for the tank. Would I be able to water change my way through this doing 10% daily water changes or will that stress my shrimp to much?
  8. I’ve been working on a green water setup for some scuds and daphnia that I got as a throw in with a shrimp order. It’s in my garage. It has a strong “earthy” smell kind of really smells like the bag of spirulina I’ve been using to feed it. Like potency is 10 x the bag. Anyway my wife whose so far been very supportive has decided that smells is not ok. My question is whether this is just a phase, maybe I have something in there that’s causing the odor besides the spirulina or if this just has an odor and I’m going to have to abandon this in favor of something live food wise that does not have an odor - been thinking I could turn this into a black worm tank or brine shrimp.
  9. Hello, I have a 75g that I recently did a 25% (roughly) water change on. It kick started an algae bloom, and I am not sure what to do. Usually what I do is just darken out the tank and hope for the best. But I am afraid that if I do that, and all of the algae abruptly dies, I will have a major ammonia spike. I have a young Oscar in there at the moment, and I know they're highly sensitive to ammonia. Am I overthinking this, and should just go ahead with a black out? Or are there any other routes I can take to clear this up? Any advice would be greatly appreciated!
  10. My whiteclouds overwintered in the Pacific NW. Just look at that green water! I've been putting my plant cuttings from my tanks in here for about the last month (not shown here because I was doing a water change and cleaning). I put some stuff from the bottom in a jar for a little experiment for my granddaughter. It has some salvinia floating on top. I'm excited to see how it goes this year. I really wasn't expecting much since it's such a small amount of water. How fun for the grand kids to learn.
  11. Okay for those that follow this 10 gallon tank was my first tank it also started MTS with me, but in the beginning it has the trio of guppies which had 2 sets of fry about a year ago, they got moved into a 20gL, which left this tank partially drained for a month or two which somehow became a cyclops tank all by itself which I tried to Nuke with periclens cuz I thought they were parasites lol, before someone here told me what they, which for the longest I used it as a "death tank" just a tank full of Cyclops and snails that Id put all the dead fish, all the dead plants, everything I didn't want in any other tanks into it and just let it rot away, no filter, no Air, then one day I decide you know what let's do that, I add a 150w led (23w) and a 10g sponge, and boom green water, I add a hang on the back and some hornwort trying to clear it up, but nope, but water parameters were good so I added four silver Molly males now my question is do I still feed them as normal because Molly's are algae eaters too a point and it's a giant tank of algae, so do I still need to feed them as regular or do I need to change something here, cuz personally tamales are doing absolutely amazing and I kind of grown fond of the green color almost it's just different than all the others cuz it's my only green one
  12. I'm recently getting back into the hobby, and I've seen various references to Ultraviolet technology used to "purify" water. Seems pricy. Will this make for a happier ecosystem, or have folks experienced some unintended consequences? (Benefits vs. risks)
  13. I’m back again!!! This tank I swear!! Lol. Hopefully I’m posting this in the correct forum. 😬 Ok, so I was having a ton of trouble when I switched my substrate to all purpose sand. Weird fuzzy stuff growing, horrible hair algae and then green water so thick you couldn’t see anything.the algae was so bad it ruined my decorations. L So I scooped all of that out and replaced it with fluval stratum, I also bought a UV filter since my four nerite snails are not keeping up with the algae like my two mystery snails did. Well....the UV filter is supposed to just clip onto my hang on back, however it is the exact same size and the spot it is supposed to snuggle into and so it will not attach. I don’t have a lot of money and would really like to make this work. Has anyone managed to rig their UV filters to work for their tanks? Thanks in advanced!!!
  14. I ordered some guppies a while back and all but one died. I don't know why, but anyway, I kept her in the 10g and green water happened. I have been trying forever to make green water inside. I was going to set up a daphnia tank, but figured that this mysterious green water tank was perfect. The daphnia is coming in tonight.... And she dropped fry in pea soup. What is the best option? Can the fry co-exist with the daphnia? At this point the daphnia will be bigger than the fry. Thanks.
  15. I was running a Ziss filter in a tank with a bunch of mystery snails and guppies and the water went green. I took the tank down and the Ziss filter has been dry for a few months. Can the media be replaced or cleaned so I can use it in a different tank without starting green water again?
  16. Hello, I have been having for sometime 6 or 8 months this problem in my aquarium. It go from green to white cloudy water then it gets clear and them go back to either green or white water color. I see to have at the bottom some green algae sometime it see to be black. My tank is a 46 gallons and house it 10 Black long fin tetras, 4 red eyes tetra, 3 Platy and 4 serpae tetra. I have 2 java fern plants that are doing really good. I do not use anything for the plants. Filtration, I have 2 each 30 gallon aqua clear and one medium sponge filter from Co-op. What can I do to get this under control?
  17. The struggle is real...but also entertaining:
  18. Hey guys, long time follower of the hobby and AQ Co-Op, but first time poster. I currently run a 10 gallon guppy fry grow out tank, small breeding for profit operation, but my water in said tank always seem to be green. I don't have any huge excess of algae on the tank wall, do 50% water changes weekly, and feed the Serra Micron food. I have tried and tried to get it back to clear, but to no avail. Any input?
  19. have what i think is green water and bought a uv filter bulb was wondering how long it should take to remove if it is green algea
  20. I had green water problem that won't go a way on my 60gallon have try everything I have reduced lighting hours increase water changes covered my tank with cover and left light of for 5days so I got a fluval uvc clarifier it been going one week but has not had any effect any one use fluval uvc clarifier had problem with it or any one have any ideas to get rid of my green water problem
  21. I've got 2 completely green 5 gallon tanks and a 20L that leans green all the time, sometimes worse than others. And my 55-gallon has been murky for 2 weeks and I'm wondering if it's going green too. So...I'm a little frustrated and want to find a way to clear it. Have any of you ever done this? Added daphnia to a tank that had green water? Did it work? I'm thinking I wouldn't need very many and then the fish will enjoy them as a treat too. Any advice on trying this method of clearing the water? And I do have a reserve of green water brewing in another bucket, and will be setting up a tank for green water eventually. Thanks everybody.
  22. So out of all my tanks, I have one tank that tends to keep green water. I have been struggling with this tank now having green water for six years. I tried to reset this 35g hex tank two years ago by removing all the substrate (sand and dirt) and replaced it with ecocomplete (3" depth. Plants in it are: 1- aquarium dwarf lily, 2- amazon swords, a full thick carpet of dwarf sag, a row of ijungle val in the very back behind the amazon swords, and frogbit that covers roughly 1/4 of the top. A few months ago I discontinued using root tabs. In regards to liquid fertilizers, A while back I was using dry ferts mixed but switched over to easy green liquid fertilizer. I have for the last month discontinued even easy green. Current nitrate levels are beneath 10 ppm. The aquarium does have 1 Nicrew Gen2 Classic on it for light, with a dimmer bringing it to 75%. Natural sunlight does get on the tank for roughly an hour each day (7 - 8 am). The light schedule is 6 am - 10 am., and 6pm to 10 pm (8 hours total). Like all my tanks I do supplement with passive CO2 (257ml for this one) daily. So my fellow fish nerms, I was wondering what is your suggestions for my next step? Should I test for phosphate or any other nutrient? And if so what tests would you recommend. Currently I use API liquid master test kit and I use the easy test strips by tetra. I do also have the API test strips too. After six years with this tank, I am at a complete loss on how to stop the green water. I am considering going back to using a UV sterilizer. I don't mind a little bit of cloudy water as long as I can see the fish, but having green soup is no fun. Edit: The current filter is the moving bed the Coop sales. Which btw is working great.
  23. I had a set up a 29g tank near a window a few months ago. It quickly became filled with green water. I had intended it to be a tank for misfits and extra fish instead of culling them. I started it with a some danios, 2 plecos and a Gourami, recently I added over a dozen Endlers and Swordtails from another tank. I could barely see the fish but I could see enough to tell they were doing fine. I routinely checked the water parameters and never saw nitrites and nitrates above zero. I figure the algae was eating it all up. I also had a sponge filter from the beginning and recently added a HOB. I left for a week over Thanksgiving returning just yesterday. During that time, the tank completely cleared up. It is the clearest tank I've ever had now. Crystal clear. Also, the bad news, I tested the water as soon as I returned and as I feared the nitrites and nitrates had spiked, once all the algae died off they could not consume the nitrites and nitrates and the bacteria was not at sufficient levels to consume convert them. Surprisingly none of the fish had died and were not even acting weird. I have added more plants, done about a 50% water change and added some Prime trying to give the beneficial bacteria time to catch up. I will also reduce feeding and may even remove some fish if the nitrites don't go down. I did not find a lot of good info about green water on the internet. Anyone had a similar experience? Am I off base on my assumptions?
  24. I have been trying to set up a Daphnia, tank for stable food supply. I have not seen much growth let alone the prolific growth your article: https://www.aquariumcoop.com/blogs/aquarium/daphnia-culturing-how-to-raise-daphnia describes here despite strict adherence to your recommendations from the article. I have an aqueon 50 on this tank with one of aquarium coops coarse foam filters covering the intake ( and an airstone) Could I be killing the Daphnia, with this filter? Matt

    What is the best advice for a daphnia culture? Do I put them in direct sunlight?
