Chloroquine Flake is used as both a treatment option and a preventative. It is a bacteriacide, algaecide and antiparasitic medication. An excellent general cure as well as a focused treatment against ICH, excess slim coat and flukes. Chloroquine phosphate has been gradually replacing copper sulfate and quinine as the drug of choice due to its superiority. Treatment: Offer as the only food source for 14-21 days as a treatment; or 7-10 days as a preventative. NOTE: Chloroquine phosphate is in high demand due to its use to treat malaria in East Africa. Due to this fact it is also in short supply.
