If the zoas built up with detritus then the copepods and other critters will pick around them and that can cause them to stay shut for a while from the constant picking.

When you say you lost them in a couple of days - what happened? Did they stay closed and melt away? were they open and pieces were missing?

Yeah i left Saturday morning after FW dipping them and went to see family for the weekend. When i got back the colony looked like the second picture. They basically melted away. They looked to completely gone by late night Monday. I tried fragging a couple areas where the zoas looked potentially capable of recovering. They are in the other tank and have not opened yet. Its possible theres excessive nutrients thought my cal, alk, phosphate , hardness are all ideal... My Nitrate is the only thing elevated at I think 40 PPM and havent tested since I did a partial water change on Tuesday night. I am planning on taking out the bio balls today or tomorrow (slowly) and switching it to live rock. I should have enough movement to avoid the detritus but thats a possibility. Have 1200 gph, 750 gph, 250 in rear power heads and have a sump pulling 400ishgph and a hob backup filter doing 300gal.... so thats 2500-3000 gal a hour on a 65gal tank.
