Hey guys, I've had my reef tank up and running for about 16 Months now and everything has been fine. Recently I had my gfo out of commission for a week while I replumbed it. It was down for so long because I thought I had the right elbows and cut the tubing apart only to find it leaking all over and had to order new elbows from brs. In that week's time I got a horrible red slime outbreak. This stuff is all over my refugium, all over my sand and starting to cover my rocks. I'm worried it's gonna start covering corals soon! I tried to siphon it all out, even in the rufgium and while it did work for a few days it comes right back. My tank is mostly softies and lps but I do have a few pieces of monti and stylo as well. What should I do? I was thinking about covering it with the lights off for a couple days but I don't want to harm the corals, please help! :headwally:
