SonRK Posted February 20, 2015 Share Posted February 20, 2015 Hey all~ I've been battling Cyanobacteria for months now. I had both Green Hair Algae and Cyanobacteria pop up at around the same (my tank is still under 1 year old, but it has been up for about 10 months now). Added a GFO reactor, and the GHA went away pretty quickly, but the Cyano has gone into two separate stages. Normal red variety, then it went away and a green blanketing one came in its place. Then that died, and the red is back. No other kinds of algae has been growing. I do have a skimmer, but I think it's being pretty close to useless. I opened up a topic here where I think it's leaking from the side, because salt creep is appearing, and you can see the brown-like sludge that it produces around the lid. It hasn't produced any good skim quality. I do run Chemi Pure Blue + Purigen together as well. I actually just read a post on here saying it's not good to run both of those. I'm about to pull the Purigen out and see if that does anything. As for flow, I have a Jebao RW-4 and Jebao WP10 on the opposite sides of my Nuvo 30L. I have them running at about 50% max, so I don't think it's a flow issue necessarily. I've been doing twice a week 15% water changes now (Red Sea Coral Pro), while siphoning, and blasting rocks / cleaning the sand. All this siphoning is actually making my sand bed really shallow. I think I need to add some more sand in the near future. I don't feed my fish a lot either, I feed such that they they finish everything. About 8 pieces of NLS Thera A, and my two clownfish finish it up pretty quickly. I guess the ONLY thing I haven't done is a true blackout (cover the sides of the tank with something dark, and keep the lights off for 3 days). I was going to take advantage of some coral/frag sale over this weekend, so I guess I could try it in a week or so once my corals are acclimated (THEN shock them with a blackout) Link to comment
Mojado Posted February 20, 2015 Share Posted February 20, 2015 One dose of chemiclean did the trick. Be sure to raise your skimmer quite a bit while using it as chemiclean will excite it a lot. Link to comment
Prisonfood53 Posted February 20, 2015 Share Posted February 20, 2015 I just did a dose of Chemiclean and it worked. After 2 days I did a 25% WC and siphoned up the cyno and it hasn't come back. Make sure you siphon all of it or I would assume it would just come back in a little time. Didn't hurt any of my corals or my goby. Link to comment
Alkomist Posted February 20, 2015 Share Posted February 20, 2015 Peroxide dosing worked wonders for me id read up on it before anything though. its a lot cheaper than having to go out and buying Chemi-Clean too. Link to comment
