Cannot get rid of cyano!

[Doug]

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.

i find it very strange that some of my corals are dying through all this and some seem to be thriving
