RECOMMENDED PUMPS

Do not use with pumps that exceed 5,000 gallons per hour. This could
damage the filter.
Do not use pumps with flows less than 2,500 gal/hr. A minimum of 2,500
gallons per hour is necessary to perform the backflush operation.
NOTE: All pressure filters restrict the flow from your pump. Expect about a
45% reduction in the water flow through the filter.
Lid Assembly
Pond water flows down through the bio-activators,
which remove suspended debris and dirt from the water.
Biological Filtration: Occurs on the massive surface areas found in the
bio-activators. Beneficial bacteria will naturally colonize on the surface
area and convert harmful pollutants in the water into relatively harmless
nitrates, which are absorbed by the aquatic plants and removed by partial
water changes. This is known as the "Nitrogen Cycle."

HOW IT WORKS
The design of these bio-activators provides unrestricted water flow to all the
surfaces for improved cleaning during the backflush cycle.
The backflushing process helps remove accumulated dirt buildup so that all
surface areas remain available for biological activity.
