I have a scroll coral that has been in my tank for about a month or so and has recently began to lose it's "skin". Some of the scolls @ the LFS where I bought it are doing the same thing. We think it is RTN, because of the rapid loss of tissue in a short period of time. I have dipped the coral in Kent's Tech D, according to label directions, 2 days ago. The coral does not look any better today. My question is how long do I wait before I dip it agian? The label directions say nothing about the time to wait between "dippings". All water parameters are fine and other corals are thriving including sensitive gorgonians. Thanks for any suggestions.
