Use Dr.Tim's Re-Fresh in your koi pond to control brown or green water issues. Re-Fresh is a potent combination of beneficial bacteria that work together to maintain clear water and eliminate unpleasant odors.
Re-Fresh should be added on a weekly basis to help maintain a clear, clean and sparkling aquarium.
Because the condition of every koi pond varies, it may be necessary to add Re-Fresh more frequently (every other day) to achieve desired results.
Directions:Shake well before using.
Dosage: Add 50 ml per 100 gallons of water.
Do not overdose on ponds containing these organisms. Wait 5 to 7 days after final dosing to add these organisms.
