Revive works great! I do a half cap to a large tupperware container or (one cap to a gallon) with saltwater. dip corals for a few minutes, then with a turkey baster, gently squirt the coral to knock off anything that may be attached to it. Place coral in another container with clean saltwater to rinse before putting in tank. You can also squirt the coral in the rinse container to make sure you got everything off.
