I agree I used chemi-clean and the red-slime was dead over nite and i cleaned it all out. Took the bioballs out of my sump(was collecting detritus and causing nitrates and phosphates to build up) and i havn't seen the slightest bit of it since which was 6 months ago. Cutting back on feeding definitely does help my nitrates and phosphates were really high and i started feeding about half as much and about half as often and havn't had a problem since. Like every1 said just stick with it and learn as much as u can to be able to solve the problems that are presented to you and everything will work out in the end. I too am pretty new to this hobby and if it wasnt for this forum i wuldnt have beautiful thriving corals in my tank thats for sure!!!
