Sorry. I mispelled it. Yes it is Coral RXone shot.
Coral Rx says to pour 1 gal of water from your aquarium into a bucket, add the vial of Coral Rx. Shake your corals in the] solution for 5-10 minutes rinse with clean saltwater and return to tank.
Im geting nw coral today from LA. I guess I can use this Cotral Rx before I put them in my tank? As I said before Im a little nervous to shake corals in the water but was it you little fish that said that they are hardy and it wouldn't bother them?
