When I was beginning into my reefing experience, I had a LFS tell me to use Red Sea X Dip as it has iodine in it and that it helps with healing of new frag cuts but is also a coral dip to get rid of any hitchhikers. My local buddies are telling me to use Coral RX Dip as it seems to be a little better product. My question is should I use one or the other or use red sea first for the iodine and then the stronger coral rx to make sure nothing goes into my tank?
