I've had my tank set up for about six months, I was wondering if cyano is a cycle thing? I have the green type is there a difference between red and green?
My tank is about 8 1/2 months old and I had an outbreak of cyano at month 6-7 also. The way I beat it was to syphon out everything I could during a water change and then kill the lights for about 2 or 3 days to kill what was left. Seemed to work well. I had started to get another small outbreak about 2 weeks ago, just killed the lights for 2 days again when I started to see it and its gone. No adverse effects to corals or fish.
Agreed. Get a piece of like 1/2 inch tubing and use it to syphon all the cyano out of the tank (you can do this and do a water change at the same time). Make sure you get it off the sand, rock, powerhead, etc. Then kill all the lights for 2-3 days. Let us know how it goes.
