Background: As long as I've had the aquarium (about a year) it has been constantly growing lots of green hair algae. (I also have to battle cyano now and then but Chemi-clean seems to knock it out effectively, but after knocking out the cyano I get overrun with even more GHA.)
I know there is a phosphate problem. I cannot measure a lot in the water (my Hanna gives me 0.08), but every surface is covered in the GHA which means there's phosphate coming from somewhere. My prime suspect was my black aragonite sand, which always kicked up a lot of micro-dust whenever I moved it. I read online some people said to rinse and some said not to rinse live sand, and I went with the package which said not to rinse, but maybe I should have rinsed.
Anyway, I took all the live sand out several weeks ago, and nothing has changed. There's still GHA growing everywhere. I'm running GFO in a reactor, I have poly-filter and a skimmer which behaves erratically (some days it almost gives me nothing in the cup, other days it fills it to the top).
I have been taking the rocks out of the tank and putting them in a bucket and scrubbing off as much as I can, and it looks nice for a little while and then grows back just as bad. I can't do anything more rough to my rocks and I certainly can't "cook" them because I have a lot of coral, mostly zoa/paly, which have been VERY successful in my tank. Maybe they like the conditions that also favor the GFO. I'm barely feeding my fish anything (when I do feed it is a tiny pinch of flake). Haven't put any frozen food in there in at least a month.
I do know that my water temps are a little on the warm side, because the JBJ is enclosed and the professional LEDs put out lots of heat. I don't really have space or money for a chiller, though.
WWYD?
