We currently have three kinds of algae.....red slime, brown "crud" and green. All at the same time!! We had the red slime so bad a few months ago that we used the Chemi-Clean to get rid of it. It worked really well but ..... here we go again! At least none of the three is really bad. The red is mostly in one corner of the fuge, the green seems to be on one area of the back glass and the brown is on one area of the sand and on the maxi-jet mag mounts. I'm going to pick up a phos pad today and put that down in the sump to see if that helps any. Our phosphates and silicates all measure zero now and nitrates are around 10 -15. Before anyone gives suggestions on cutting back on feeding, water changes, running carbon etc....we've done all of that. As per Randy in the chemistry forum, we are just going through one of those normal cycles for a young tank.
BTW, how does a UV sterilizer work to control the algae?
