The magnetic attraction immediately begins when negatively charged
TerraPond is introduced into your pond water and begins the
micro-encapsulation process. This electrical ion exchange process is
also referred to as "flocculation."

Personally, I'm often quite suspicious when a product needs to
introduce the notion of some rarifed process of physics. Magnetic
arm bands, anyone?

Anyway, you have dirty water?

How big is your pond, and describe your filtration system.
