A coarse mechanical filter media that can be used in any type of filter, but needs to be combined with a finer type of filter floss to be most effective.

This filter media works well as a middle layer in my filter setup. It catches larger debris that passes through the mechanical layer, keeping the water cleaner. I wash it every few weeks and it holds up well over time.

I placed it between the mechanical and biological layers. It helps prevent clogging and keeps the filter running smoothly. Works best when paired with fine filter floss.

Great for overflow systems. It traps particles without blocking water flow. Easy to rinse and reuse. No issues with performance after several months of use.
