Yeah I pretty much triple dosed the first time, there were a LOT of them, and this is after a siphoned, the water actually turned a bit of a reddish tint to it, I was scooping them out as I saw them floating, but man there were so many. Ended up losing my foxface (the best algae eater that has ever lived) and a bicolor angel, a day or two later, guessing there were too many toxins.
I re-dosed some today, but there weren't as many so hopefully it'll get them all, if not I'll dose again, and again and well ok maybe I'll stop one of these days. I got a "yellow coris" wrass, but he disappeared and never saw him again.
