i use two little fishies revive. I know alot of other sps keepers use it as well. Not saying necessarily that it's the best but it works for me.
coral RX for me
CoralRx designed only for flatworms.
Revive, interceptor, and a QT are a must if you are into sps.
A quick dip in revive when the corals get in, then 24 hrs in a QT with interceptor and then another dip before they go into the tank.
