Commercial Strength MinnFinn™ Max is a concentrated treatment for large to commercial sized ponds. One liter treats up to 8,000 gallons of water when treating goldfish or koi. 

MinnFinn Max Pond

Our most concentrated version of MinnFinn. A 1 liter kit will treat 8,000 gallons (30,280 liters). MinnFinn Max was developed with large pond and tank fish keepers in mind. The kit comes with the liter of MinnFinn Max and a Bag of NeuFinn for treatment neutralization.

As with all MinnFinn products, once the one hour treatment is neutralized it is like it was never there. No water changes no worries.

MinnFinn Max is a hazmat to ship so special consideration and pricing is required when purchasing.

Application of MinnFinn Max (Part 1) 

• One bottle treats 8000 gallons. 
• It is recommended that the user wear gloves and eye protection when applying MinnFinn. 
• Make sure you have an accurate pond volume to avoid over dose and under dose. 
• Increase aeration to pond to maximize oxygen levels and to ensure proper mixing of treatment. 
• 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. 
• 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. 
• 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. 
• Let MinnFinn treatment run for one hour. 
• Normal treatment behavior will be lethargy, mild to moderate increase in respiration, and possible mild agitation.
