The AQUA SURE Bottom Drain and Dome Range provides a high-efficiency, low-maintenance solution for pond owners seeking superior water quality and cleaner pond floors. Designed for both small and large ponds, this range effectively removes debris and solids directly from the pond base, reducing maintenance while improving filtration performance.
Unlike traditional pump-fed systems that can liquidize solids into fine particles, the gravity-fed design ensures larger solids are directed straight into your filter system for easier removal and better water clarity.
For ponds requiring aeration, our Aerated Bottom Drains enhance debris removal by up to 30%, while also improving oxygen levels for healthier fish, plants, and beneficial bacteria.
