Cannot get rid of cyano!

My small tank hasn't had any issues since the initial setup and its now 13 months old...that said, theres only 1 eel, cuc and some soft corals. I did get rid of the cyano before I started dosing in the larger tank. Are you saying its a combination of the above?

I do regular weekly 10% water changes, and vacuum the substrate every 2 weeks, run HC GFO, carbon, and maintain balanced ca and alk and mag, change filter socks every 2 days, skim wet, run a sulphur denitrator, but once cyano rears its ugly head your pretty much screwed, you can do water changes til the cows jump over the moon but it just won't work, I'm thankful for chemiclean.

Sounds like you did it right, not sure how it could have messed you up, run lots of air to keep oxygen up, chemiclean is an oxidizer so maybe there was an underlying issue with some corals that caused them to die, they may have died in time anyway. See it through, get rid of the cyano and regroup.

Good luck!

And what is it that I wanna hear?

I'm looking for answers that might actually help. Not generic responses that I can find with a quick google search

Some of us are trying to give you sound advise and share our real world experiences to help you make informed decisions, a lot of people have used chemiclean successfully with no ill effects in all types of reef tanks, I researched it like crazy before I did it and have no regrets, I think you must have some unseen issue with your tank, which could be responsible for the cyano in the first place (I had some acans die that caused mine).

I wanna hear that you are making progress, are you?

And I took your advice and dosed chemiclean yesterday. Waiting to see results

[Cal_stir]

OK, you should be seeing results by now, tomorrow the cyano will be gone.

Well I really hope your cyano clears up.

I too have used chemi-clean... In fact it's in my glovebox. When cyano happens to one of my customers tanks, they want it gone now. Instead of saying itll be gone in 3-4 weeks with me doing some dedicated water changes and adjusting chemistry, perhaps adding a power head. I will sometimes just add chemi clean to get rid of it, all the while knowing the I will have to adjust the problem that was causing it in the first place in the future. However the customer is happy for the meantime and I can fix the issue after.

Marlo, please keep up with the water changes. It will help in the long run.

Chemi clean can sometimes be like a bandaid fix. Not really fixing the problem causing it.

The only other thing that I can think of that could make a difference is that I have changed everyone of my 50 tanks off of nls foods as I find them to be really dirty. I am now feeding 95% hikari both frozen and pellets (marine a, marine s, as seaweed extreme) and have had significantly less brown algae on the glass, and less outbreaks of cyano.

Water changes are your friend.

A combo or even just one of the factors
