Had a recent Fish kill
I lost several Trgger Fish the nitrite level was off the chart.I vacumed a lot of junk from under base rock and in the Tank.There are two small groupers and two small niger triggers in the Tank I replaced the two triggers I lost.I did several 50 percent water changes and the reading was in the middle range still a little high.I think I should feed them every other night to try to reduce the nitrite to acceptable levels.The Tank is a 55 Gallon Tank with a hang on wet dry filter with a built in skimmer and I have a 60 Gallon whisper Filter on it.There was no ammonia in the tank but the nitrite level was high at the time of the fish kill :x .I know most of the problem was over feeding and to high of a bioload.The fish are all going to stay so the bioload will be heavy I could use some advice from the fish Gods on this Matter thanx for the help
