Help Zoas slowly dieng off

Hey guys i could use some help starting sometime last week my zoas in my frag tank have slowly been closing up and developing this brown film which is eventually killing them. I have tried dipping in Revive, Peroxide and even a lights out thinking maybe it was cyano or something but it hasn't help. Here is a pic of one of the colonies you can clearly see the brown on them. I have been blasting them with a turkey baster on a regular to keep the detritus off them. Any ideas what i could do would be great!

It's dinoflagellates. Covers zoas and other corals and eventually they die. Do a search on reef central. There's a 5000 post thread on it
Good luck

Instead of starting a new thread, i figured I would share a similar zoa problem I'm facing...

A few frags I have are suddenly not opening. They were once bright growing but now all closed up. I've dipped them in revive and even did a major water change. What else could this be? Alk/ Ca important for zoas?

Try putting them in an area of higher flow.
