About the throw in the towl

[ponokareefer]

I am having the same problem in my system with cyano, although it hasn't killed anything, yet. I did turn off my lights for 60 hours straight, and this knocked the cyano down drastically, but not completely. The 60 hours without light had no ill effect on my corals or anemones.
I am planning on a 3 day complete black out shortly to completely get rid of the problem. This means you need to completely cover your tank with blankets to ensure no light gets in. There has been a few threads on www.reefcentral.com on this issue and this has been where I have done my research on how to fix this problem.
You would have had a problem that started the cyano and you could have fixed it, but once it has established, you need to do a 3 day blackout to get rid of it. I would get rid of any media in the canister filter, as this may be one of the reasons this problem started. I have also added extra flow, lowered feedings and changed out my bulbs. None of these affected the cyano at all, and it continues to get worse all the time.
I am planning on doing my 3 day blackout the weekend of September 10 to 13th. I can let you know how it goes if you want to see how mine turns out before you give it a try.

I got rid of my cyano easily by vacumnng with everything off, I cut my lights back 2hs and added 2 koralia2's aimed at the worse areas no probs I left it like that and changed my water schedule to 5% every 3days and wala

I had to do a blackout when I had a bad algae bloom a few years ago same thing usd blankets because even ambiant light will help it I also used weiss algae remover gone in a few days not sure if it's safe to use with reefs though

I do completely vacuum out the cyano every week, and aimed my powerheads at the problem spots, but it just always comes back in a new spot, and gets worse each week.

Hmmm,

Post your water parameters, a picture of your display tank, sump and/or filtration setup, maybe answer a few more questions..and I guarantee that the people and combined knowledge on this board can solve the problem for you.
Money back guarantee.

I feel bad for the guy, was hoping to see a response back from him but here goes nothing.

This is the problem with this hobby. And I have been through dinos, and cyano. It's a headache but you can get through it. Like mentioned previously, ditch the fluval and move to a aquaclear. Also, wouldn't mind seeing a picture of your rock work, and how the power heads are set up.

You can get through this. Star with the mentioned about and turn off your lights, put a blanket over the tank for 3days and start dozing kz coral snow every day. This has been the most effective way for me and works like a charm.
