nightmare

Come home tonight and all my fish are either died or gasping at the top. I do a quick 20 gallon water change. My tank is 56 gallon. I have co2 but it wss barely on because I have mostly java fern. The water did seem warm but the thermometer ssid 80 but I lowered it just case. The old water did smell a little. The ammonia was 0. The fish ate fine this am. The only thing out of the ordinary was loaches were swimming all around and they usually stay under the rocks. I know you can't really to help but I needed to vent

Any aquarist worst nightmare. Sorry for your loss. Could it be an end of tank dump of CO2?

Tank dump:

The pressure in the CO2 tank remains fairly steady until it's almost empty. Then it starts dropping relatively quickly. The more the pressure drops on the input side of a single-stage regulator, the more the pressure rises on the output side. And that means more CO2 flow through the needle valve, so the tank empties faster, which makes the situation increasingly worse.

For example, if I set my single-stage regulator to 15psi, and allow the CO2 tank to empty, the output will rise to a maximum of 30psi.

If you have a single-stage regulator, a small CO2 tank that completes the final stages of emptying quickly, and an efficient diffuser than can successfully dissolve all that extra CO2, it can result in disaster.

Many folks thing tank dump is a myth, having had a tank empty without disaster. But more likely they've never seen it because they're lacking one or more of these conditions. For example, my fish survived one dump because the reactor was already at the diffusion limit and the excess simply burped out, with little change in ppm. The next time, I had an Atomic diffuser with no such limit, but it was also survived because I was using a 20lb. CO2 tank. Since the increase occurred gradually over two weeks, the fish successfully adapted, even to the final value of 60ppm. If that had been a 5lb. tank or smaller, the levels would have risen faster, and my fish would probably have been killed.

The End of Tank situation would explain the cloudy water. Lets see what the water tests from Pacific Aquarium shows...? Never act in haste.

My heater was also off I had it set at 78 and when I put the thermometer in the temp was 82. So ill do another wc tomorrow and wait for things to settle down. Meanwhile in the 26 its crowded but everyone seems fine

Sounds like you're successfully salvaging this, rather than quitting. Glad to hear it!

Update. I lost everything except for gbr (and the fis I was able to transfer). Ive been testing my water reg my nitrite is 0 my ph 6 my ammonia is .25. I went to Pacific today to buy fish but after talking to the salesman I decided not to. He felt my ph was too low. I added from the 26 three glo light tetra. It's been over a hour now and they seem fine. The gbr gave them a hard time but that's stopped. If they are doing well mon and my water test come out as they should ill head over to monster.
Thanks for all the help
