Two Little Fishies ReVive Coral CleanerTM is a new product developed by Julian Sprung for cleansing live stony corals. Its formula is based on plant extracts, not iodine. Use for all general purpose live coral dipping, as a part of acclimation to aquariums when corals are first received, for rinsing prior to shipping, and for rinsing newly fragmented corals, such as at coral farming facilities.
