Large Blue Coarse Pre Filter Sponges

Description

We use these pre-filter sponges on our tank and pond Filter intakes to prevent fish and large debris from getting into the filter.

These pre filter sponges also help provide additional biological filtration media, which holds beneficial bacteria and helps to cycle your tank.

Care: Rinse the sponge regularly, as you would a sponge filter. When clogged with detritus, rinse the sponge in clear tank water until unclogged.
