Hi, I got a new tank about 6 months ago. Moved everything over and things were going great. Then, about a month ago - BOOM. Brown sponge like algae everywhere, green hair everywhere and cyano too. I know I need to throw a powerhead on the backside of the rock pile to pickup the flow to get rid of the cyano. But what the heck is this brown stuff? It doesn't look like any of the diatom stuff I've seen before. And, I cannot figure out what the heck happened. It literally happened over the course of a couple weeks. The only thing I can think of is I make the RO water in a bucket in the sink. Occasionally it will sit for a day or two and maybe one of my kids splashed some soap in there (soap has lots of phosphate in it) while washing their hands? I don't have a phosphate test yet because I've literally never had a problem with it. Very frustrating.
Last night, I went lights out and dosed 3% H2O2 at 2ml per 10gallons. Turned skimmer off. Any other advice? There is a yellow tang and a clown which I feed very little and not so often. I had about 20 peppermints from an aiptasia outbreak a while back that were doing great...but seemed to have disappeared since the outbreak.
