I finally got my nitrates under control, and red slime algae is disappearing, but now I've got green algaie growing like crazy. All readings are at 0, except nitrates @ appx. 10. I have a wet/dry that I'm using as a sump, and no bio-balls, and I just removed the filter box and filter pad and now just have my overflow hose drain directly into the sump. It's a 55 gallon with appx. 100 lbs. of live rock, couple of power heads, 4 small fish (2 damsels, 1 perc, and one spotted pajama cardinal), an engineer goby (I've don't think a sunami could move as much sand around as he does), and a dsb of about 4-5 inches. Any help would greatly be appreciated.
