Chloroquine Phosphate – The Saltwater Aquarium Wonder Drug now readily available. Kick Marine Ich, Velvet, Brooke, Uroema to the curb!

Chloroquine phosphate is considered a “wonder drug” in the Saltwater Marine aquarium hobby. The drug of choice for many public aquariums including the Georgia Aquarium. It has been widely used by hobbyists in the early days of the marine aquarium hobby and used in the aquaculture industry since the 70s and 80s. It is typically unavailable to the majority of the reefing community due to it normally being available only through a Veterinarian via a prescription. I feel your pain if you are like me and tried to get Chloroquine phosphate from a veterinarian. It is difficult to obtain, so I have worked with a national laboratory to obtain a 99% pure Cholorquine Phosphate solution that is suitable for disease treatment. We obtain Cholorquine in bulk and split into 10 gram units so it is affordable and available to reef aquarists. Don’t take just my word about how great this fish medication is, hear about from a vet below:

  • Highly recommended that you use a digital scale to measure your dosage to ensure accuracy
  • Keep medication in a cool, dark, and dry pace. Chloroquine Phosphate is heat and light sensitive
  • If water change is performed, Chloroquine Phosphate will need to be re-dosed for the amount of water changed. You do not need to dose Chloroquine for top off water.
  • Conduct a 25% water change and remove medication with activated carbon once treatment is completed

Additional Notes

  • Not reef safe – Chloroquine Phosphate is meant to be used in a quarantine for prophylactic treatment or in a hospital tank for active infection treatment.
  • We do not ship Chloroquine Phosphate next day – it was never our intention to sell this to be an emergency source. We want you to have a medication supply ready and pre-treat your fish to prevent outbreaks. If you have an infected fish and you need treatment now we highly recommended going to your LFS and obtaining Copper. Most of the diseases Chloroquine phosphate treats are extremely deadly and can kill a fish overnight
