Description
The Tempest Filter is a premium pond polisher designed to deliver crystal-clear water through a powerful combination of mechanical and biological filtration. Its proprietary air-syphon cleaning design and premium media make it ideal for high-performance pond systems requiring simplicity, reliability and clarity.
