The Bottom Drain and Dome are designed to give a high-efficiency low maintenance system when constructing a pond, as it draws debris and solids from the pond floor. Using a gravity feed system is more beneficial as the solids get fed straight into your filter system for removal and not liquidized into fine particles as within a pond pump, the finer the particles the harder it is for your filter system to remove them, resulting in a poorer quality of water. Why An Aerated Bottom Drain? The benefit of having an Aerator on your Bottom Drain is the rising air bubbles make an uplift, this circulates the water towards the Bottom Drain making the Bottom Drain up to 30% more efficient at removing debris and waste from the pond. Not only does it help with the performance of the bottom drain but also aerates the water making for a healthier environment in your pond. Our range of Pond Bottom Drains are available is different sizes and models of aeration catering for all requirements.
