I jsut purchased 20 lbs of fuji live rock and I had it in a bucket to cure. The directions that came with it said it is best to keep the water at 80 degrees with the water circulating. I put my heater in set on 80 and about 4 hours later I checked it and my heater was not working properly because the water was about 100-110. Is everything dead or can I still put the rock in my tank. Thanks . Debster
