Cannot get rid of cyano!

Arent you the guy that is against water changes?

If so, physically remove with a syphon, clean your top layer of gravel, every day for 3 days, and I bet that will fix your problem.

Start changing your water more often if youre not. I believe, if this is the same person, this is the second time you have had issues that may be solved by water changes.

(just before you feel like pulling your hair out).

It will not release the nutrients back into your system it just breaks it down so it can be pulled by the skimmer as dead waste.

I run a sulphur denitrator that is controlled with an ORP controller and had it running while I dosed chemiclean, the denitrator functioned properly the whole time, therefore, the chemiclean did not kill the good bacteria in the reactor so I dought it killed the good bacteria in my tank.
The package says it is safe and after using it I have to agree, I so absolutely no ill effects other than a whacked out skimmer.

Just do it, you won't regret it.

25yrs. reefing......dozens of tanks both with and without sand. My experience, ONLY, if I had sandbed I had cyno....if I run bare or starboard, no cyno. Period. Nothing in between.
and yes I know lots have sand and no cyno but thats it in a nutshell for me.

yeah sand is most likely the cause of many problems. but i just dont like the look of bare bottom. so i went with about an inch of sand.

i think the risk of sand is worth it

+1 on the sand, I just can't bare the site of a tank without it.

i just dosed 20 scoops of chemiclean. how long does it take to get rid of the cyano, its starting to kill my corals.

can i still run a skimmer fully open?

[Cal_stir]

follow the instructions

no skimmer, UV, ozone, chemipure or carbon for 24 hours

multiple air stones is good.

it takes 24 to 48 hours

[Cal_stir]

Turn your filtration back on after 24 hrs(except skimmer), keep the air stones running.

Be ready to start daily 20% WC after 48 hours, run fresh carbon, it will take 2 or 3 days before you can run your skimmer.
