MinnFinn Max is the commercial strength version of MinnFinn. This treats 8000 gallons whereas the MinnFinn regular strength treats 2240 gallons.

This two-part treatment treats a broad spectrum of fish including parasites, external fungal and bacterial infections, and many more. If your entire pond is overrun with infection or illness, then MinnFinn should be administered to your water body. Fish pond water treatments generally take only 1 hour and are neutralized with the included MinnFinn Neutralizer. Many illnesses can be eliminated in as little as 1 to 3 treatments. The MinnFinn treatment will decompose itself into natural elements, leaving the formula non-toxic, safe for humans, pets, fish, wildlife, and the environment. MinnFinn does not discolor water and does not require water changes.

MinnFinn Treatment Uses

Easy to use
Your MinnFinn® treatment takes only one hour, compared with conventional treatments which can take days to weeks. The treatment is halted by adding NeuFinn, eliminating the need for a water change, and providing a safety net if too much MinnFinn® is applied.

Application of MinnFinn Max (Part 1)

  1. One bottle treats 8000 gallons.
  2. It is recommended that the user wear gloves and eye protection when applying MinnFinn.
  3. Make sure you have an accurate pond volume to avoid over dose and under dose.
  4. Increase aeration to pond to maximize oxygen levels and to ensure proper mixing of treatment.
  5. When treating flukes and Costia, leave filter online for the first treatment. When treating other diseases placing filter on bypass is optional. If left online, expect small impact on nitrification for 2 to 3 days. Bypass filter for further treatments.
  6. Dilute the required quantity of MinnFinn in a 3/4 full 5-gallon bucket using water from the pond to be treated or tap water for up to 250 ml of MinnFinn. Use a separate bucket for each 250 ml of MinnFinn to be applied.
  7. Spread the mixture around the entire edge of the pond or in the upwelling from an air diffuser to ensure good mixing, which will reduce the potential of an area of high concentration fish may pass through.
  8. Let MinnFinn treatment run for one hour.
  9. Normal treatment behavior will be lethargy, mild to moderate increase in respiration, and possible mild agitation.
  10. See required NeuFinn* directions for preparation prior to the end of the treatment.
  11. If fish appear severely distressed indicated by rolling over and appear to be falling asleep, apply NeuFinn* immediately anytime during the treatment.
  12. Do not use with any other treatment.

Preparation and application of NeuFinn (Part 2) REQUIRED

  1. Mix the required amount of NeuFinn neutralizer in 3/4 of a 5-gallon bucket with either pond water or tap water. Use a separate bucket for each 1/4 bag of NeuFinn applied.
  2. After the one-hour MinnFinn treatment is completed, apply the dissolved NeuFinn to the pond in the same manner as you did the MinnFinn around the perimeter of the pond or over an air diffuser.
  3. Return water flow to the pond and/or filter.
