Highlights

ProForm-C® is a broad spectrum treatment that is safe and effective for the control of diseases caused by Ichthyophthirius (ich), Costia, Trichodina, Chilodonella, Oodinium and fungal infections. It is a malachite green and formalin combination that is considerably less toxic to koi and goldfish than other similar products in the market.

Required treatment time is generally 3 days and bypassing the biofilter is not required. One quart treats a 3,200-gallon system three times and one gallon treats a 12,800-gallon system three times. For use with koi only—not for food fish.

Cannot be shipped in temperatures below 40ºF.
