How Does the UltraZap Gravity Fed Pond Filter Work?

The UltraZap Gravity Fed Pond Filter uses three filtration stages to help maintain clean and healthy pond water.

1. Mechanical Filtration

Pond water passes through sponge filter media that trap dirt, debris and suspended particles. This helps prevent larger waste particles from circulating through the pond.

2. Biological Filtration

The included bio blocks provide a surface for beneficial bacteria to establish themselves.

These bacteria help convert harmful ammonia into nitrites and then nitrates, supporting a healthier and more balanced pond environment.

3. UV Clarification

The integrated 8W UV clarifier helps control free-floating algae responsible for green pond water.

By reducing suspended algae, the UV clarifier helps improve water clarity without the need for chemical algaecides.

Together, these filtration stages help maintain cleaner water while supporting the pond's natural biological processes.

Important Installation Information

This filter must be installed as part of a correctly designed gravity-fed pond filtration system.

The filter needs to be positioned so that the water level inside the filter is the same as the water level in the pond.

Correct installation is essential to ensure that water flows through the filtration system as intended.

If you're unsure whether your existing pond setup is suitable for a gravity-fed filter, contact us before purchasing and we'll be happy to help.
