How can I prevent foam?
Orb-3 Antifoam does a great job of quickly knocking down foam, and as long as it is active in the water body, it will continue to work to stop foam.

However, if foam is a common problem, it pays to examine the root cause. Sometimes it is as simple as an air leak in the system; it can also be caused by certain types of chemicals (typically polymers) & algaecides, detergents, low levels of calcium, and most commonly organics in the water. An enzyme treatment can often be a big help.

If foam is a constant aggravation, give Orb-3 Water Garden Enzymes a try.

Where can I learn more about good pond management practices?
We recommend "The Efficient Pond Management Handbook" by Ryan McCaw.

This handbook is designed to give the average pond owner the knowledge and skills needed to manage the pond.

We like this book because it stresses a natural approach to pond management and a philosophy of solving the underlying problem rather than chasing symptoms.
