Cyano Die off period

[ReefsandGeeks]

I'm not really new to the hobby, but haven't had this issue in a long time. I've had a cyano outbreak for some time in my tank. When I tested the water, I saw the nitrates were high as I had recently had my canister filter I use for beneficial bacteria leak on me and tried running without it for a while. Long story short, I got a new canister filter and began carbon dosing again to try to get back to near undetectable nitrates. Dumby me, I completely forgot about phosphates and remembered I had also stopped running GFO, so I'm running that again, but the cyano hasn't gone away yet, about a week or a little longer into using GFO again. How long should it take for the cyano to die off once the phosphates are brought down? it's getting annoying and is starting to hurt my coral by growing on it. I've been trying to keep up with hand removing it from the coral, but is an annoying battle to fight.

are you dosing vodka? vodka dosing can promote cyanobacteria growth.

Phosphate doesn't have much to do with cyano. it's a bacterial sheet, not algae, and the most frequent cause is either sunlight getting to a tank or the lights wearing out. Tends to be seasonal, as sun-sources change with the passing seasons.

I have been dosing vinegar , only about 10ml/day in a 40 gallon. However i've done this for a couple of years with no sign of cyano before. Is there anything I can do to get rid of it? It's a daily battle trying to get it to stop growing on my coral and it's already killed about 30% of my coral by covering it and I'm guessing blocking the light before I'm able to get it removed.

Chemiclean is a safe way to rid your tank of it. I syphon everything I can, then use chemiclean, water change 2 days later. I not one for adding anything to my tank but sometimes you just can't help it. But I have had good look with this product in my LPS, softy tank.
