So after performing my salinity drop to kill the ich in my main tank. I brought it back to .025 and turned on my halides. The brown hair algea is out of control like 1" or better. I knew I would kill stuff off and have to cycle a little again. But this is ridiculous. I just ordered more phosban for my reactor and added 3 large turbo snails. Any thoughts why this got so bad actually within days. It's nasty looking. I've had tanks for years and never had this.
