The Kusuri Defoamer is completely fish safe and constructed of food-grade materials.
The Kusuri Defoamer works fairly quickly and can be used as often as required.
Early in the season especially on new ponds, foam formation is typical.
Continuous foam on surface water should be looked at since it may be caused by insufficient bacterial activity or inadequate filtration.
Dosage:
Pond water should have 100ml per 1000 gallons (4564 litres).
