I bought about 125 lbs of live rock from an individual who said it was cured. I brought it home and put it in my tank. Then I bought a HO light and within 48 hours I had brown stuff all over my rock!! Today I noticed bubbles on some of the rock and little hairs? My questions is, Is this normal? I have a skimmer whick just started to pull some crap out of the tank and I just don't know if this is right or not. Oh yea one more thing I've been putting a Calcium supplement in the water as per me LFS. Is that okay?
Thanks
