Cutting and fitting it

The 200 x 100cm sheet can be cut with sharp scissors to fit filter trays, chambers or baskets, so one mat often serves several filters. Use it as a middle layer, after coarse mechanical media and before fine floss. Rinse it in pond or tank water rather than tap water to protect the bacteria, and when it needs replacing, change only part of the media at a time.
