Hi all! Relatively new to the forums. Read a lot but I don't post. But it's kind of an emergency this time!
I recently went through a fumigation (full tent) I have a 220g and I wrapped my tank. Luckily, al the fish survived. I have a colony of 12 frontosas starry nights and a a few more random cichlids I got from a breeder. I used to have close to 30 fish.
Unfortunately when setting back up the sump (sump was taken out during the fumigation) I realized I lost most, if not all my beneficial bacteria (stored in buckets outside the tent) and my tank was crashing fast. I lost seven 5-6 inch frontosas in the first few days. Lost my Giraffe hap and then went 3 days without any fish loss. I was testing water every day. Dosed due to a ammonia and nitrite spike (this was quickly resolved). And then I lost one of my Rostratus.
Last parameters were,
Ph - 8.0
Ammonia - 0ppm
Nitrite - 0.25ppm
Nitate - 80ppm
I took water tests everything is back to normal minus a slight nitrite elevation.
Now one of my large Frontosa 8-9 inches has been swimming at the top of the tank, Sometimes vertical (nose down), breathing heavy and fin rot. I have been working on the tank perimeters daily to stabilize as best as I can and I'm tired of throwing away dead fish. Please help. Thank you!!!
