All Tanks Stable, No Sick Fish. So Naturally...

All fish will have a problem if you do not provide adequate water surface for gas exchange. Leave a small gap at the top of the tank so that air exchange can happen across the entire surface. It will also make the tank more cory friendly.
 
I do have a gap at the top for that very reason.

Actually strangely enough my edge is the only tank I never had any problems with. It cycled really quickly and everyone in there is healthy, no algae or cloudiness...and everyone gets on! Thank goodness because if something did happen it would be a nightmare to fix.

I cannot imagine how painful a fish-in cycle with daily changes would be in that tank!

I think I somehow managed to cycle my filter in a 23L tank, although I'm waiting for confirmation once I get a nitrite kit next month.
Imagine if I had to do 99% on a 76L, that'd be like 7 10L bottles and I'm running out of dechlor due to daily water changes in the old tank and weekly 20L (sometimes 30L) in this other tank. Although I do put in some non-dechlorinated (but left over night) 1.5L water during the week.

As soon as I get my salary, new dechlor and nitrite kit are mandatory. Whatever is left over I'm wondering if I should spend on ph or nitrate kit or save part of the money just in case filter dies. Although it's working smooth now.

It's more about the shape of the bloomin thing. Having done a fish-in cycle on a 65l rectangle where you can take the top off to change water, I can say that was bad enough. More than one change per week for the edge is probably worse than that! I bought the edge siphon and it's next to useless and the net is worse... Getting fry out is impossible!

....HOWEVER... all that aside, I still like how it looks and how you can look in from the top without distortion. And to be honest, surely the reason that 99% of us start the hobby in the first place is for something pleasing to look at!

Dechlor is more important, you shouldn't experience a nitrite spike at this point and if your fish start acting weird then a big water change is the way to go, regardless of what your stats are.

Well, I use a plastic container to take the water out and a net to take the heavier stuff out of the tank, as I can't get the hose to work properly. I might use that water pump my dad has, but not sure how good it will work.
I never had any fancy tanks to know how an edge tank works but it's easy with tanks that you can lift the whole lid off. Dad is still working on a proper lid for the tank, it will have a light, some glass to protect the neon light and plastic edges to hold it atop the tank.

I just changed 30L today, which is about 50% of the volume I have, if you don't count the air side of the tank.
The only weird thing I see as odd behavior regarding my fish now is the catfish's constant digestive problems.
With flakes he gets constipated, a bit bloated and struggles to eliminate the dump while floating like a balloon till he has pooped. With bloodworms he doesn't get bloated but he seems to have trouble digesting the food (expels undigested worms sometimes) and throws gas a lot.
And I cannot seem to find epsom salt (not even sure they know what that is at the pharmacy either as I don't know its name in Romanian), the salt I have is non-iodine salt and marine salt, which cannot be used in his case. I do have a bag full of uncooked peas, but none of the fish like them. o_O
 
Wish me luck... i have been soaking the cat litter in readiness for the tanks change today!
 
im torn weather to use cat litter or john innes soil or a tetra plant substrate. have u used cat litter before? wish i had more time to decide my new tank comes on tuesday :hyper:
 
The cat litter is a pain in the bum, it is supposed to be low dust but even after washing loads, soaking for a week and then more washing it is still making the water cloudy...

I didn't even soak for more than half a day in my sand's case, but it was sold specifically for aquariums though. I didn't bother with cat litter as I can't be sure I can find one that's not treated with anything.

Cat litter is very dusty, it takes ages to settle... Much longer than sand. However it has now done so and it does look good. We have moved two platies, two guppies and two brave little platy fry (now too big to eat!) and four pygmy cories in. They look so tiny in the 65l! I hope they do ok.

Also bought 6 peppered cories for the 200l today, I love them! So full of character.

I think I am going to stop there and get rid of the edge... I think.

If I had to get cat litter and wait that long, mom would have asked me to give her the bowl back LOL. But not so lucky that the sand might not be good enough for my water sprites. And the catfish keeps unrooting the plants out of it. Tomorrow I'm putting a rock to keep a sprite branch there. But for some reason I still expect to end up with a completely torn branch again. The filter had one around... now it's no longer there. -.-

My fish also look tiny in my 76L, although one of them is supposedly a giant fish lol. (though Hoplos are even tinier compared to giraffe catfish... I saw a pic with comparison between the two species... O_O It looked like a gigantic hoplo with a long snout!)
