Coral Rx was developed in 2006 for two purposes: to treat corals suffering with parasites, and as a prophylactic measure to promote healthy corals before parasites or bacterial infections become harmful. Coral Rx is tough on parasites, yet gentle on your coral (contains no iodine or oxidizers) allowing you to be proactive in protecting your investment. Coral Rx can be purchased in three different concentration levels: Coral Rx, Coral Rx Pro and Coral Rx Industrial. Coral Rx (8oz) is ideal for retail store sales, and produces approximately 12 gallons of coral dip. Coral Rx Pro (1oz & 4oz) is ideal for online orders to reduce shipping cost, and produces approximately 17 gallons and 66 gallons respectively. Coral Rx Industrial (8oz & 16 oz) is ideal for organizations caring for a large quantity of corals, and produces approximately 295 gallons and 590 gallons respectively.
Coral Rx can be used in treating many types of live corals; soft, LPS and SPS. Coral Rx should be used in treating corals that have parasites or other bacterial infections. Additionally, it should be used as a prophylactic treatment before bringing live coral into your aquarium.
