I will second Reefrunner's and Michel's suggestions about Melafix. I am currently using it in my reef tank which houses LR
, inverts, and fish. So far no ill effects at all. Everyone seems to be doing great. In fact, my Coral Beauty's tail is healing up quite nicely and I am only on day two of treatment (his frayed tail was the reason I started treatment).
As Michel says, TURN OFF THE PROTEIN SKIMMER when using Melafix. You will have a monster of a bubble bath within minutes of adding it if you don't. I didn't know this before hand and all of a sudden found a "foam party" in the sump. (They should really put this in the directions).
On thing to consider. Will the FW
dip do any good for bacterial infections? I though those dips were only for parasitic problems. I could be totally wrong, however...
