hard corals not doing well

michael81 · 05/02/2012, 07:41 PM

Hello, i have a 90 gallon with a 55 gallon sump, the tank has been running for about 6 years. Out of nowhere my corals started to go downhill, they will not extend there polyps at all, my acaporia is staring to die. It seems to be mostly hard corals that are not doing well, with the exception of a couple of soft corals that will not open up at all. The only one to actually start to die is the acaporia. But i know something has to be done and fast otherwise they are going to start dying, ive had some of these corals for five+ years so i really do not want to lose them any advice would be great, thanks
