What is Coral Rx?

Coral Rx was developed in 2006 for two purposes: to treat corals suffering from parasites and as a prophylactic measure to promote healthy corals before parasites or bacterial infections become harmful. Coral Rx is tough on parasites while gentle on your coral because it contains no iodine or oxidizers, allowing you to be proactive in protecting your investment.


Coral Rx can be purchased in three 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, most suitable for the home hobbyist. Coral Rx Pro (1oz & 4oz) is perfect for online orders to reduce shipping costs and produces approximately 17 gallons and 66 gallons. Finally, Coral Rx Industrial (8oz & 16 oz) is ideal for organizations caring for many corals and produces approximately 295 gallons and 590 gallons, respectively. 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 was designed by keeping the health of your coral in mind. Blue Oceans Coral's proprietary blend of natural ingredients contains no iodine, which is known to stain corals, nor does it contain oxidizers whose by-products are often toxic and continue to react with the surrounding tissue. Independent research also questions the effectiveness of iodine treatments. 

Coral Rx removes many of the hard to deal with coral pests like Acropora-Eating Flatworms, Montipora-Eating Nudibranchs, and Zoanthid-Eating Nudibranchs.

How Does Coral Rx Work? 

Coral Rx can be used to treat many types of live corals; soft, LPS, and SPS. Coral Rx should be used to treat corals that have parasites or other bacterial infections. Additionally, it should be used as a prophylactic treatment before bringing live coral into your aquarium.

Coral Rx should not be used on fish, shrimp, crabs, snails, clams, or other invertebrates. We have not tested CoralRx's effectiveness on Acropora Red Bugs.

Independently Tested


Coral Rx was independently tested by Andrew Lynford, M.S. in Biology from Hofstra University. This investigation attempted to quantify the efficacy of three chemical flatworm controls: Flatworm Exit, Coral Rx, and Povidone. His research is available in a featured article published in Advanced Aquarist, April 2009. Below are excerpts of his findings:

  • Coral Rx was the most effective treatment
  • Coral Rx performed well as a coral dip, and it would be advantageous for coral aquaculturists, wholesalers, retailers, aquariums, and hobbyists to use this product when quarantining newly purchased corals.
  • Chemical treatments are utilized as a preventative protocol to eradicate flatworms before introducing them into an aquarium. These chemical treatments are referred to as coral dips.
  • Quarantining corals and live rock with coral dips is the best way to deal with marine flatworms. It prevents their introduction and circumvents the problems associated with convolutrilobid toxin release.
  • Harvesting coral reef taxa (species) to replace livestock lost through convolutriloba toxin release is environmentally costly and should be prevented by using coral dips.


  •  Dosage per gallon of dip
    • Coral Rx: 20ml or four capfuls
    • Coral Rx Pro: 30 drops
    • Coral Rx Industrial: 10 drops
  • Shake the bottle of Coral Rx. Add dosage as stated above based on product purchased to 1 gallon (3.8 liters) of saltwater from the aquarium. Mix well. Using a small powerhead, keep the water moving and place coral in the coral dip. If you do not have a powerhead, gently shake coral in the coral dip. Keep coral in the coral dip for five to 10 minutes. After five to 10 minutes, remove the coral and discard the coral dip. Do not reuse the coral dip as parasites may release toxins. Rinse coral with clean saltwater and return to the aquarium. 

Do not add Coral Rx directly into the aquarium.
