Treat & Neutralize

MinnFinn treats external diseases in fresh water and marine aquatic animals. Treatment is easy, completes in 1 hour, and requires no water or filtration changes. Instructions walk you through 2 easy steps:

  1. Add medication
  2. Add neutralizer to remove medication

Fish and coral stay in their tank for treatment, which minimizes their stress.

MinnFinn is effective against a broad spectrum of diseases, so you don’t need a microscope to diagnose your disease before you start treatment.

Best of all: MinnFinn is non-toxic to you, your aquatic animals, your plants, and the environment. Most fish medications on the market contain cancer-causing ingredients that are not legal for humans (silica, Gentian Violet, Glutaral, Malachite Green).  MinnFinn is one of the only medications available that do not require a CA Prop 65 safety warning.
