Fluval Pre-Filter consists of inert, solid ceramic rings used to trap large and medium solid particles before they clog the finer sieves of the media baskets above.
The media forces water into many complex paths as it moves through this layer. This further increases its mechanical and biological activity and expands the actual contacted filter area.
An additional benefit, it supports large populations of bacteria for proper biological action on ammonia and nitrite. This reduces the need for frequent changes of the active filter media.
Pre-Filter is permanent, and requires only occasional rinsing. This media can be used in fresh and marine environments without difficulty.

Great product, houses bacteria, dont forget to replace regularly
They say to replace this once every 6 months, half at a time. Basically, just replace them when you start to see them disintegrate. This filter media is great and gives home to the beneficial bacteria you need in your tank to maintain the bio-load. This is a great product from a great company.
