Hello. I am new to the forum. My daughter has had a saltwater tank for about 8 months now. Its a 37 gallon tank. After some mishaps in the beginning, everything in the tank has been alive for about 4 months now so I think we finally got everything balanced. My concern is this "fuzz" on some of the live rock. Its white and almost gelatinous looking. It is on about half our live rock. Any ideas and what, if anything, I need to do about it. It does come off easily, but I did not know if this is something I should actually be doing. Thank you!!
