Concrete pond bottom drains pull settled waste and debris off the pond floor and channel it to the filtration system, cutting the manual cleaning out of pond maintenance. The same principle works in concrete fish-tank and aquarium systems. Choose 50mm or 110mm for a standard installation, or the 50mm custom option for special setups. A dome-only part is also available for replacements.
