As Coral Rx says, “Don’t Risk It, Dip It.” Coral Rx has done extensive research to produce a product that is effective toward eradicating common coral pests like Acropora Eating Flatworms “AEFW”, Red Flatworms, Montipora Eating Nudibranchs, Zoanthid Eating Nudibranchs, Bristleworms, Zoanthid Eating Box Snails “Sundial Snails”, Zoanthid Eating Spiders and some Filamentous “Hair” algae. Yet it is gentle to the host coral and causes not damage.
