MinnFinn Marine & Reef Treatment
MinnFinn Marine & Reef is a fast, broad-spectrum treatment that clears parasites, bacteria, and fungus from marine fish in a single one-hour dose. It is a non-antibiotic, oxidative treatment that is 100% reef-safe and invert-safe, so you can treat right in your display tank. 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 tank volume to start a powerful one-hour treatment, then add the included NeuFinn neutralizer to stop it immediately and return the water chemistry to its original, safe state. No large water change is required.
Features
What It Treats
MinnFinn Marine & Reef targets a wide range of common marine problems, including:
- Marine ich (Cryptocaryon) and marine velvet (Amyloodinium)
- Flukes, Trichodina, and Costia
- External bacterial and fungal infections
- Coral pests such as Acropora-eating flatworms, planaria, and red bugs
How to Use
Always read the full instruction card before dosing. In short: dose the MinnFinn concentrate based on your tank volume to begin the one-hour treatment, then 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. Run your skimmer off during treatment and back on after neutralizing, and keep an eye on livestock throughout.

FAQ
Is it really safe for my corals and inverts?
Yes. MinnFinn Marine & Reef is formulated to be 100% reef-safe and invert-safe, including with LPS, SPS, soft corals, and invertebrates, so it can be used in a display tank. As with any treatment, observe your livestock during the process.
Do I need a water change afterward?
No large water change is required. The NeuFinn neutralizer stops the treatment and returns the water chemistry to its original state.
Will the parasites build resistance to it?
No. Because MinnFinn works by physically breaking down cell walls rather than acting as an antibiotic, target organisms do not develop resistance over repeated treatments.
How many gallons does one kit treat?
The 50 mL kit treats up to 110 US gallons. Match your dose to your actual system volume using the included instructions.
