The octagonal design provides maximum strength, and a much easier shape to camouflage than circular or rectangle designs. With 2 bulkhead openings, pipes can be installed from either side. The second opening can be used as a back flush to perform water changes or connect multiple pumps or plumbing lines. The two included Matala mats have two times the biological benefit and will last up to four times longer than traditional mats. These boxes come with self-tapping stainless steel screws for easy installation and corrosion resistance. Lastly, the waterfall snout is reversible. Install in the usual way for basic installation or reverse the snout for a more advanced waterfall appearance.

Elite Series Waterfall Filters are absolutely the strongest, most durable waterfalls on the market! A contractor favorite, Elite Series Waterfalls come standard with Matala Biological Filtration Mats and include a Landscape Lid for concealing the unit within the landscape.
