So I went away for a few days from my tank and came home to my skimmer not working at all, due to it being stopped up by chaeto, and a tiny little bit of red cyano appearing in the middle of my DT. I also noticed my Koralia 1 was fluttering a bit due to snails getting in it and popping free the propeller. I have fixed both these problems yet the cyano continues to grow. Well I tried vacuuming it all out but that didn't go all too well and now it looks like this!!! I put it a new filter sock stuffed with Phosguard from Seachem and some new carbon as well. Nothing else has changed with the tank and this is my first run in with this algae and I've had the tank for over a year now. I run a 15 gallon display fuge, which I just set up, and I also have an Aqua C Remora Skimmer that is running very well now. I feed every other day and every so often I'll put in some cyclopeeze or coral frenzy. Didn't have this problem before with this exact feeding. I tried to do as must research as possible and fix the problem myself but it just seems to be getting worse so now I need some help! Thanks!
