How It Works
-
Calculate Your Pond Volume
Use our free calculator or measure your pond dimensions to determine the right dose for your system.
-
Measure Your Dose
Follow the dosing chart on the label. Day 1 gets a loading dose, then switch to the weekly maintenance amount.
-
Apply Weekly
Dilute with pond water and apply evenly. Turn off UV for 24 hours. That's it — crystal clear results, week after week.
