Kusuri Defoamer can be used as often as necessary and works very quickly.
Foam accumulation is common on new ponds and early in the season. Continual foam on the ponds water surface could be caused by poor filtration, but as in nearly all cases it is caused by proteins in the pond water which stick to air bubbles resulting in the build up of foam on the water surface. Kusuri Defoamer can quickly and effectively remove this unsightly build up, but may be for a longer term solution a protein skimmer should be installed.
Kusuri Defoamer Dosage:
Use 100ml per 1000 gallons (4564 litres) of pond water. Foam should disappear after 1 hour. Treatments can be repeated hourly if necessary. To dose the pond simply fill a clean watering can with pond water, then add Defoamer. Gradually sprinkle across the surface area of the pond.
