Cyano

What is the best way you guys get rid of cyano i have been batteling it for just over a month now i do a 20% water change weekly

Blow it off the rocks, vacuum it out.
More flow, or better directional flow
3 day lights out

I have corals in the tank as well i didnt want to deprive them of light for 3 days

I have coral in my tank and a while ago I had cyano I did a big water change clicked the lights of for 3 days and it went away...but you also have to find out whats causing it and fix the problem. .for me it was over feeding

3 day lights out has been done many many times, it will not harm the corals.

+1 but you have to figure out where the excess nutrients are coming from. Check your nitrates and phosphates and be carefull and don;t overfeed.

The rock came from my old nano tank i was away for a week and my house mate said he was feeding the fish and turning the lights off turns out the lights were left on 24/7 and he fed them once i got back most corals were dead and tge tank was covered in cyano i scubbed most of it off before adding it to this tank but i think some stayed on i feel like i dont feed enough i put a little pinch of food in at night thats it and feed mysis every second day

Haha I am seeing the same thing. Rather have a few patches of ha than a carpet of cyano tho.

That's it haha I'm gonna get a lawn mower blenny maybe

Seriously you are lucky if the cyano is disappearing that fast. Mine has taken the better part of a year to abate. I am keeping an eye on the hair algae tho because if I am just exchanging one for the other then I probably haven't impacted the underlying nutrient issue. I have no idea what conditions would have to change to favor hair algae over cyano, but they both need the same nutrients I think. It should be easier to find animals to eat the HA, but I don't believe that will fix a serious outbreak.

I am working under the assumption that phosphate is leaching from my rock because I converted a very dirty softy reef into an sps reef without changing it out. I also feed good quality non-flake food sparingly to a minimal fish population and have a good water purification system giving me 0 tds output, but my phosphates remain borderline to high even running gfo. You could have a similar issue.
