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?

follow the instructions

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

multiple air stones is good.

it takes 24 to 48 hours

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

With everything I have heard, and by all means this is just speculation, but is it possible that with your new flow, that there isn't a proper exchange of water from the bottom of the tank to the sump? I know you have MP40s now, and they are great but you still need some movement up and down, I do this by directing the returns downward... food for thought.... couldn be why some corals are reacting harshly because they arent getting the oxygen provided by the sump? Feel free to give me a call Marko if you run into more issues....

i have no idea. i just cant see there being issues with flow. i get mini sand tornados rising from the sand when the powerheads speed up.

also one of the corals that i pulled out that was dead was an sps that was 6 inches from the top of the tank

it was good this morning and now all white
