I have a 10g , 36g and a 180g tank. I did my regular water change and cleaning (50% on 10 and 36 and 60% on 180). Clean algae, etc... All tanks have been running for 6 months to a year and are fully cycled. I did not have Prime so I went and got some AmQuel from PetCo since my LFS was not open. I did my water change and added salt and conditioner as it was filling through python. Fish ate great about 2 hours later.
About three hours later, I came home and only in my 180g, fish were breating really hard (fast, open mouth). Other tanks were fine. I imediately checked water - Ammonia - 0.0, Nitrite 0.0, Ph 7.6 (normal) and nitrate 0-5 (very slight). Fish active and swimming.
My daughter wakes me early and says fish are all on top of water gasping....I immediatly grab the python and start another water change. While draining, I test water and it still is the same? I do about a 75% change anf add a different conditioner (Aqua Safe) and do not use salt this time.
I come home and some fish have color back, and are active. Breathing slightly heavy but better. HOWEVER, in my 36, I have a dead Rasbora, a dead Angel and anothe large Angel laying on her side, plus all fish breathing heavy. I immediately start draining and testing water Everything was fine, but Nitirte which was nearing .25....I do a 75% water change and add conditiner and no salt. Fish Ok but one Angel still slow and probably won't make it....
I can't think what is wrong?? I did everything as normal,, no changes at all.....
1) Could too much salt cause this? I go by instructions but maybe too much?
2) AmQuel? Bad bottle..too much, etc...No date on bottle...
3) I cleaned and changed all filters last week, water perfect all week?
Any Ideas?????
I plan on doing another big change on both tanks later today.....No issues with the 10g....???(Did a 50% anyway? All tanks have been cycled for 1 year + and no new fish introduced, and no signs of any sickness prior....
