So I came home today to find an explosion in my tank. I've had a little build up of brown algae on a few rocks and my sand prior to today but tonight it is everywhere. Also in addition to this brown stuff i have huge patches of white algae, I believe coralline? What in the world is going on here and what action should I be taking? I know the brown stuff isn't good but what about the white. Water parameters are in check as of yesterday. PH 8.2, ammonia,nitrite,nitrate 0, calcium 400 and 0 PO4. I'm going to run a nitrate test but it was zero yesterday and I only fed one small flake this morning which my clowns devoured. :shock:

Correction....the PO4 levels are < .25. Its hard to tell depending on how I look at it but I'm pretty sure its almost 0

OK. I am getting some increased growth in green, pink, red and purple algae as well. Are there and good critters that I could add to my tank to deal with the substrate? I have two Nassarus Snails that dig around in it but that's it

So is some sort of gfo reactor or something in order? I've been using ro/di water for top off and reduced feeding. What would cause phosphates to show up? It was definitely zero the other day when I checked it. Also any idea what that white stuff is? Its like a bright white algae looking stuff. Looks like purple coralline algae only white.

The White looking Coralline Algae stuff is just that. Its dead Coralline Algae.
Also, Phosphates are in the food yoiu feed your fishies. Gotta watch which brands yoiu use, and what you use. You can use a Reactor to get rid of it, or sump with Macro Algae, or a ATS(Algae Turf Scrubber). But, I wouldn''t worry if I were you, those are Diatoms you are seeing right now, and they will take care of themselves without anyting being done.

So why would that coralline be seemingly spreading? Unless it grew a bunch and then died today? It definitely wasn't all over the place before. I have regular coralline growing as well. Also there is some green algae growing. This is crazy man. I thought I had somehow managed to avoid this. I'm a month and a half into having my tank.

Well i guess I'll grab some more snails and a glass scraper. If its the norm then I'm happy. It was just crazy to come home to tonight after all that time with nothing going on and bam! algae everywhere
