Bad cyano

[jason604]

After buying a few new corals my tank got cyano outbreak right away. It started as being on sand bed only to rocks on sand now n kinda covering some corals. How I get rid of it? I've been vacuuming my sand of nasty
Gunk during water changes now.

Chemiclean works really good. Just follow directions and it works just like they claim.

Can it be harmful to fish n corals? Will just water changes work?

I use it whenever I have cyano and it works great. My sps don't seem to mind at all. I know many people who also use it in a mixed reef. I have also had success fighting algae by doing very large water changes every day for about 4-5 days. And I'm talking like 80%+. Thats just my personal experiences though.

You could try the KZ cyanoclean. It seems to take 6 to 8 weeks to work but no need for oxygenation or water changes or crazy skimmer foaming.
