Chloroquine Phosphate Aquarium Dosing Calculator

Choloquine Phosphate or CP is an aquarium medication that is used to treat marine ich, marine velvet, uroema, and brook. It is most effective at 50/mg per gallon as many hobbyists are not able to obtain CP from a Vet (get from a Vet if you can get a prescription). As CP not obtained from a Vet cannot be guaranteed to be 99% pure, a 50/mg per gallon range is dosed to make up for slighly diluated CP (Most CP purchased online will be anywhere from 95 – 98% pure). You can use the calculator below to estimate how much Choloquine you need to dose in your quarantine tank. This is very useful if you need to do water changes as you can quickly calculate for your replace water.Effective CP range is 40mg/Gallon – 80mg/Gallon.
