Perameters?

Ive had kenya trees, and polyps do that to me. Its one of 4 things. Wacked parameters/salinity, High nutrients, too much/little light, or too much/little flow. I Have polyps in my 65 under 250 W MH...they shrivle up if there is too much light or too little flow. I have to keep them on the bottom with a powerhead at the top of the tank pointed strait at them. Otherwise they curl in, and rarely open.

Can you post information on your set up and water parameters? That would help a lot in this situation. Considering many corals are affect and not just one, it seems you may have an issue with your lights, water parameters so other factors like skimming etc
