Coral Rx was designed with the health of your corals in mind. The proprietary blend of natural ingredients contains no iodine, which is known to stain corals, nor does Coral Rx contain oxidizers whose by-products are often toxic and continue to react with surrounding tissue. Coral Rx removes many of the "hard to deal with" coral pests like Flatworms, and coral/polyp eating Nudibranchs. Coral Rx is hard on parasites yet easy on corals making it a perfect prophylactic treatment protecting your coral investment. Whether or not you quarantine your corals before putting them in your aquarium, a dip in Coral Rx decreases the probability of adding a parasite into your aquarium eco-system. Coral Rx can be used in treating many types of live corals; soft, LPS and SPS. Use it to treat infected colonies and before bringing new live corals into your aquarium.
