One of the many questions @Cory gets is: How many... So, in today's inaugural episode of 'Care Forum Investigates', where average fish keepers of average intelligence attempt to solve simple problems, the question is… How many gallons of water can I put in a 10 gallon tank? I'm not the only one apparently. According to Google people have asked: Not having the fancy scientific equipment to answer the question 'How many gallons does a 10 gallon tank hold per hour?', in this episode we will confine ourselves to the 'how many gallons can I put' question. Equipment used: Non Affiliate Links Aqueon "10 gallon" aquarium: https://www.amazon.com/Aqueon-Aquarium-Fish-Tank-Size/dp/B01MRCNVSY/ref=asc_df_B01MRCNVSY/?tag=hyprod-20&linkCode=df0&hvadid=167116240456&hvpos=&hvnetw=g&hvrand=8960182847743316893&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9010107&hvtargid=pla-338193400514&psc=1 United Scientific Large Beaker: https://www.amazon.com/United-Scientific-BG1000-10000-Borosilicate-Capacity/dp/B007QO3RDA Medelco Small Beaker: https://www.fishersci.com/shop/products/pyrex-griffin-beakers-15/02540M The result after adding 37.85 liters of RO/DI tap water 25°C (but with no dechlorinator) is seen below: The aquarium began to leak at about 9.95 gallons apparently because of the lack of an unbroken seal along the top most part of the rim. Discussion: While technically possible to put 10 gallons of water in a 10 gallon aquarium, you may not be able to do so without a substantial leak. It is also possible that if we were to increase the total dissolved solids (TDS) by foregoing reverse osmosis water, that all the little solids in the water would plug the leak along the rim, thus allowing for the full 10 gallons of water. Next week on 'Care Forum Investigates': How many gallons of water can I put in a 20 gallon aquarium?

The baby 3" fire eel will do fine in my tank of several hundred neon tetras. Well it did do just fine, 2 months later it was a 6" fire eel and there weren't any neon tetras left..... 😔

I thought this might be fun to see what people's stats look like. Active tanks only (something, plant, animal, invert, living in it). 226 / 25.4 / 9 Enough tanks that normal people think it's crazy, but few enough that aquarium people know I'm a newbie.

285 / 31.7 / 9 Biggest is 90 and smallest is 10. I've added 3 tanks in the past 3 months. Now Alexa thinks I order lights and dimmers on a regular basis and just today reminded me it's time to order another one.

This was technically yesterday though I finished working super late. I'm almost done with my stand for my 50 hex! The only steps left are concealing the remaining 2x4s, staining, and sealing it. I also picked up my black lace angels at the post office this morning.

I think the worst advice I got was just get a tank its a cheap fun hobby. Now I have 7 tanks and spent thousands hahaha

Just discovered clown killi fry in my nano-pond tonight! Wasn't sure it was going to happen, but so exciting!

"Is this possible????" Yes. I'd say it depends on the plants she has, the chemistry of the water, the livestock, and the lights. I run low light, and whether I add fertilizers or not, I have to periodically, and quite often, throw out excess Water Sprite, which can be a very fast grower for some folks. And years ago, I had a 75 gallon tank--very low light, no purchased fertilizers ever--that grew so thick with Java Fern and Java Moss (slow growers) that the fish could hardly get through it. And it almost seemed like the less light I gave the tank, the better those plants grew. (Much to my dismay, however, Vallisneria won't grow well at all for me.) One thing I've learned is that a lot of aquarists have their superstitions. I figure that many of the things they do oftentimes don't necessarily help or hurt. I never argue with people about their rituals, though, and I've learned to just ignore a lot of advice that seems pointless to me. Take my advice with a grain of salt too. I'm probably what most people would consider a lazy aquarist. I tend to stick with easy-to-keep fish and plants that seem to do well for me without too much work.

As of this reply here are the total stats so far counting everyone’s tanks! 10,726.5 Total Gallons 34.37980768230769 Average Gallons 312 Total Tanks

From the ashes of this aquarium... a tiny Phoenix!!!! He must’ve been super tiny when all that nonsense happened. Man I love this hobby! 😁

Moved my pond inside

It's possible to keep bettas in smaller tanks, but getting the stable parameters, heating/filtration properly done, and having enough stimulation is tricky. It's like trying to keep a Great Dane in an apartment.

Finally got my linear piston pump/air loop installed!

Wanted to introduce myself here. My name is Colin and I have been in the hobby for less then six months. I was able to get a fully stocked tank for free 👍 It came with 4 angle fish which included unknown to me a pair. This has led to 4 tanks as of now. Cory’s videos on YouTube have been great! 1st picture is just after I got the tank. Second is some time after when I got rid of those nasty plastic “plants”

this is charlie mint i had in an aquarium previously and converted it to partially submerged, partially emersed. it is vining like crazy but it has also started flowering! ive never had this plant flower before. this is the nano pond style tank i have going with shrimp and juvenile daisy ricefish

I can't believe the things I got away with as a youth with well water. I would sometimes do 100% water changes on my tanks with plastic plants, rinse my filters with hot water, plus all sorts of stuff with under gravel filters. If there had have been any chlorine or chloramine in my water, I probably wouldn't be in the hobby today. This was pre-web, and I didn't have any books or magazines. I can't remember any tips from those days of Madonna and GnR, but I was good at DIY carbon replacement for undergravel filters. 😉

@Streetwisemy guy just hit 28 pounds and is a puppy dog.

Well if we are counting reptiles and outdoor tubs that changes a bit 😂 the new numbers are 2,431 gallons/ 86.7 avg/ 28 "tanks" I think I would have to count because some of the reptile tanks aren't measured in gallons. This is my snapping turtle that is In the my 450

Mine is very typical and too common which is bettas don't need filtration. Mine still did ok due to the consonant water changes I did but still. Wish I had a better story.

Looks like spawning to me!

@Daniel, I'll be waiting with bated breath for next week's episode, and continuing saga, of CFI (care forum investigates). 😉

Hitting them with a big water change is not likely the answer. I would go with regular smaller water changes in an effort to have clean water and just stick to that. But on the other hand it probably wouldn't hurt to hit them with a big water change. The point is I don't think any of that really matters. I kept them in slightly acidic water with a temperature slightly above 80°F. But I don't think precise water parameters in terms of pH and temperature are critical either. I think anywhere between 6.6 and 7.4 will probably work just fine for pH. And any temperatures between 78°F and 83°F will work. As long as the water is clean, I think the most important ingredient is just a good diet. It's hard to go wrong with black worms, blood worms and brine shrimp. Variety in diet is always a good thing as is giving them a lot of protein. The fish will breed when you have a well-fed, healthy paired male and female who feel comfortable in their environment. That's the formula. Several hundred baby angelfish on an Amazon sword leaf being watched over by mom.

I moved to LA area in April They are doing great so far

I can confirm that fish disease is ichy 🤢

Most of the ones I've heard are covered here, though I'll add that someone at Petsmart about 15 years ago told me Ich is just a generic term for fish disease.

@siniardem I have had great luck with peace lilies either in my HOB or in a shower basket hanging at the back of the tank. I just pruned them back a couple of days ago because they were growing out from under the shelf. There are two other clumps from the pruning that I gave to some fish friends.

Like @Andy's Fish Den they seemed very similar to scalare to me (I've never kept altums, though I have always wanted to). If my leopoldi ever had the inclination to be skittish, that was beaten out of the them by my cats which spent an inordinate amount of time of on the top rim of the angelfish tank. I think that this desensitized them when they realized that no matter how scary that cat monster above looked that in the end nothing ever happened so the angelfish quit worrying about anything. I kept mine at a pH near neutral and temperature of about 80°F. In the end they were bulletproof. It didn't seem to matter what I did or didn't do they just rolled with the punches. I think they were by wife's favorite fish of all time. @TJB5280 I think you are the right track. Getting a half dozen and letting them sort out the pairings has always worked for me. The longer I keep fish the more mysterious it all becomes. I really have no idea why some things work and some things don't. Biology has too many variables to be reduced in to a simple formula (at least for me). I think I have tried enough different things over time that at least something was bound to work out. I look forward to seeing the updates on your angelfish project!

I finally mounted the TV in my bedroom. Quite the relaxing view.

Today, and yesterday, I painted one of my walls black, got new dressers for the aquariums, and got a new desk. First, I had to get rid of the old cabinets and move the tanks somewhere else temporarily. After that I painted the wall, put the new dressers and desk together, and put the tanks on the new dressers. And lastly, I put all my stuff in the drawers.

Hey folks, I'm an Irishman living in NY. Got back into the hobby this year after many many, many years of not being a fish keeper lol. I have a Betta, 4 Oto's and 2 Nerites. Pleased to meet you all 😀

Something low tech and inexpensive has been a game changer for me. Bamboo Steamers. I use them for all kinds of seafood and veg. Using nothing else but an inch of water and dinner done in minutes. I use kale or cabbage leaves as liner so clean up is easy.

"Two common plecos should keep the glass clean your 29 gallon." To be fair, they certainly kept the glass clean lol

Make sure you check/install your smoke detector in your fishroom today 😉

Logitech G512 I recently switched over to mechanical keyboards and am a big fan of this one. IMO it's a good value for the price. I also have a razer blackwidow elite but prefer the G512 for the better feel and sound of the keys on the board. They are marketed for "gaming" but I use them as productivity keyboards and bought them with their linear switches.

any of the liquid carbon fertilizers will melt val, including excel and the co-op's easy carbon. They work great at being an algaecide but valisneria doesn't like it. In my experience, i removed the dead leaves, and the val came back over time. As long as the root structure didn't die, you should start to see new growth, as long as you don't keep dosing the excel, as the carbon is being depleted by the plants and water changes.

Nice looking discus!

It sounds like you need a way to vent out the heat. If you don't have any ventilation you will also run into moisture issues as well. If you have a portable AC unit, you can do that, but make sure that it has a dehumidifier in it as well to help with any moisture issues. I don't think you insulated it too well, for most people insulation holds the heat in a house, but in your case, you are keeping the heat from penetrating through from the outside into the house.

Cycle a 40 gallon breeder from day 1 with about 20 feeder goldfish. Edit: I forgot to add that this is from a "reputable" LFS. (We don't go there anymore)

I can't really tell much from the photo. Fungus or bacterial would be my first guess based on fuzz. I would think moving would be best.

Water changes, water changes, and more water changes.......never ending saga of keeping big cichlids!

@gcalberto normally if you’re seeing lots of fungus in the first 24-36 hours the eggs weren’t fertilized

Hi All, My name is Teddy and im from London. started the hobby a few months ago and loving it so far! Excited to learn more about the hobby and interacting with everyone 🙂

Loving that racking system

Michelle planted a couple of 10s, 20s and 40Bs while rocking the Aquarium Co-Op merch. I performed a few water changes and took photos.

Cool! I look forward to seeing pics of your tank. I'll get some of mine up soon. I had some Rainbow fish in my 60g. They're some of my favorite freshwater fish.

Some new friends: these guys (kribensis) arrived today and are doing well. 8 total, unsexed and about an inch long. I also picked up 6 multifasciatus recently in another tank. Both tanks have some guppies for dither. The kribs will be headed to a larger tank once they’re a little bigger and we see what the genders are. Many of these tanks are in my office; this is my newest setup and I still haven’t decided what to put in it. I picked up this 5g used for $20 and used Marimo moss for most of the plants so far.

I'd say that everyone should have good kitchen knives, ones that take a good edge, stay sharp, and can handle both delicut things and be a workhorse too. Now you don't need 5 billion of them to be successful in the kitchen, but knives like other tools do have their specific jobs. But I will say once you have used a really good Japanese or German chef knife you will never want to go back. In my opinion most folks could survive with two good knives in their kitchen, plus maybe a couple good paring knives. My two most used knives pictured below are both Japanese steel one is my 10" chef knife and the second a 6" utility knife, they've been with me for years and will do most anything I call on them for. One thing to remember, knives must fit you, just like a bicycle, bra, or gloves, there is no one knife for everybody's hands. You should take some time a test drive them, go to a good kitchen shop, maybe bring your own potato and carrots to try the feel of the different blades. Oh and you don't need to necessarily buy a whole set, all of them may not fit your grip or needs.

I added a doser to my 55 display. Pump 1 is Easy Green, pump 2 is Easy Iron and right now pump 3 is just water. It is a Jebao DP-4 and was easy to calibrate and program but not app based which is fine with me. Plus way cheaper than other systems. I use Voss glass water bottles for reservoirs.
