MinnFinn Freshwater Aquarium Treatment
MinnFinn Freshwater Aquarium is a fast, broad-spectrum treatment that clears parasites, bacteria, and fungus from freshwater fish in a single one-hour dose. It is a non-antibiotic, oxidative treatment that is plant-safe, so you can treat right in your display aquarium or pond. Browse the rest of our fish medications and water care.
How It Works
MinnFinn uses oxidative disinfection technology adapted from the medical and biotech industries. Instead of an antibiotic that pathogens can adapt to, it physically breaks apart the cell walls and membranes of parasites, bacteria, and fungus, so resistance does not build up over repeated use. You dose the MinnFinn concentrate based on your aquarium or pond volume to start a powerful one-hour treatment, then add NeuFinn to bring the water back to normal.

How to Use
Always read the full instruction card before dosing. In short: remove activated carbon and other chemical filtration, then dose the MinnFinn concentrate based on your water volume to begin the one-hour treatment. Add the NeuFinn neutralizer to stop it and restore normal water chemistry. The neutralizer can be added at any time, which is helpful if you ever need to end the treatment early. Keep aeration running and watch your fish throughout.

FAQ
Is it safe for live plants?
Yes. MinnFinn Freshwater is plant-safe when used as directed, so you can treat a planted aquarium.

Because the treatment is neutralized after about an hour rather than lingering for days, the impact on your beneficial bacteria is minimal. Remove chemical media during treatment and keep aeration running.
How many gallons does one kit treat?
The 50 mL kit treats up to 220 US gallons. Match your dose to your actual system volume using the included instructions.
Do parasites build resistance?
No. MinnFinn works by physically oxidizing pathogens rather than as an antibiotic, so resistance does not build up over repeated treatments.
