Ultra Black Filter Mat - 1.25" Thick, Coarse | 9 Sizes

Green Vista's Ultra Black Coarse Filter Media is ideal for catching small and large particles of debris in ponds, water gardens, waterfalls and other water features. It is essential for any koi pond or water garden bio-filter system and is also effective for aquarium, aquaponics, or hydroponics filtration systems. This black mat's coarse density allows good, beneficial bacteria to colonize, grow and thereby break down toxic Ammonia and Nitrite in water. The filter media also allows water to flow freely through while trapping debris and not clogging. Using this filter mat helps to ultimately make the water clear and healthier. Use it in a variety of applications, such as a skimmer, a biological filter or even a small prefilter on the pump of your water feature.

This filter mat is not toxic to koi, other fish, plants and other pond life. It is made in the USA.

Clean the water in your water feature with Green Vista's Ultra Black Coarse Filter Media Pad.
