Cyanobacteria has me contemplating trying Chemiclean or something...

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)

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.

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.
