These black filter media pads with a coarse density allow water to pass through as they catch debris. They are made for use in ponds and aquariums.
This set includes 5 filter pads. Each pad is 1" thick, 12" wide and 12" long.
These filter mats can be cut to fit just about any pond filter equipment, including pond skimmers and waterfall bio filters.
Use water from a garden hose to rinse debris from the pads.
