Pondmaster Carbon and Coarse Polyester Replacement Media. One complete set of filter media for the Pondmaster 1000/2000 series filters provide mechanical, biological, and chemical filtration. We recommend the coarse poly be used as the first layer of the media and the carbon coated material as the second layer. This produces a gradual filtration process.
– Contains one polyester filter pad and one carbon coated filter
– Resists compacting

– Fits all Pondmaster 1000/2000 series filters
