Melosu58 and Kurt Nelson. Thanks for your help but I believe I figured out the problem. I recently bought a tank level glass hood that sits between my lighting and the water surface because the plexi one I made was sagging and looked nasty. I just removed the glass for one hour. The Stars begain to sprout. 3 hours later they are back to normal. I guess the glass hood was too restrictive. I guess its back to the drawing board for a plexi hood. Any suggestions for hood matiral? I try to keep a tight seal to prevent evap.
thanks.
