JBL FilterBalls - nothing new, or is it?

Who hasnt heard of them, the bio-balls, cascades and porcupine filters? They have been used in trickle filters, bio-filters and pond filters and everyone asks themselves: what is actually the advantage? They have a smaller surface than foam and cost more money - why? The JBL Research and Development Department has made a surprising discovery: JBL’s newly constructed design of the familiar bio-balls, the JBL FilterBalls, enable aquarium-keepers to clean the filter at longer intervals.

When adapting the new filter (JBL CristalProfi) for the European market, aquarium-keepers expressed the wish for the intervals between cleaning the filter to be extended. For this reason JBL developed the SSK system (Sediment Separation Chamber System) for JBL filters, in which, with the help of the newly designed FilterBalls, the particles of dirt are deposited in the first filter chamber (sedimentation). As a result, considerably less dirt passes into the following filter material, which consequently takes longer to become blocked, thereby lengthening the intervals at which the filter needs to be cleaned.

Tests in other filters produce similar results: even without the unique SSK system of the JBL Filters, the service life of the filters is lengthened. The 23 mm JBL FilterBalls have a pore width of at least 2 mm, a key factor for the self-cleaning effect. Layers of bacteria coating can flake off without blocking the material. The synthetic material is neutral in water and is therefore suitable for use in either freshwater or saltwater.

A 1000 ml pack contains 100 FilterBalls.
