The TetraPond Waterfall Filter allows to you to easily create a beautiful waterfall for your pond. This easy-to-assemble filter provides both mechanical and biological filtration and can be easily hidden with rocks and pond decoration. Benefits of the TetraPond Waterfall filter include increased aeration for your pond and cleaner and healthier pond water.
Pond water is pumped into the bottom of the filter. It rises upwards through a fiber mat, which traps suspended dirt and debris.
Beneficial bacteria will naturally colonize on the rough surfaces of the lava rock or other bio-media (not included) and convert harmful pollutants in the pond water into relatively harmless nitrates. Nitrates are absorbed by aquatic plants and can also be removed from the pond through partial water changes. This process is known as the nitrogen cycle.
TetraPond’s new open-profile bio-activators offer a superior filtration performance over closed bio-media and lava rock. These bio-activators have been perfected and used in the commercial aquaculture industry where demanding filtration is required due to extreme environmental conditions. The advanced technological design of the bio-activators provides a large active surface area for the beneficial bacteria to colonize.
