Hello, I am wondering how much of a salt fluctuation is safe for the filter bacteria in a brackish tank. I did a big water change in my brackish tank about a week ago and I suspect I might have ammonia levels although I haven't tested yet. I brought the specific gravity down from 1.010 to about 1.008, m fish didn't mind one bit. I am wondering if this is too high of a jump for the bacteria? How sensitive are brackish filter bacteria to salt level changes?
