The AQUA SURE Weighted Suction Dome is a premium solution for pond owners who want the benefits of a traditional bottom drain without costly or invasive modifications.
This range improves pond circulation and water clarity by drawing in suspended particles and debris directly from the pond floor. The result? Reduced maintenance, improved filtration efficiency, and a healthier aquatic environment.
Unlike permanent bottom drains, the AQUA SURE Dome installs quickly and easily — no digging or pond liner alterations are required. Simply place the dome at the lowest point of your pond, where it functions like a sump drain and directs solids efficiently to your filtration system.
Each dome features a precision-engineered 380mm base plate set at the optimal height to ensure maximum suction and water draw. Even in ponds with uneven bases, the design guarantees consistent and unrestricted water flow.
Quick and easy installation — no pond liner modifications required
Efficient removal of debris, sludge, and solid waste
Low-maintenance, durable construction
Improves water clarity and circulation
Promotes a healthier pond environment for fish and plants
The Aerated Weighted Suction Dome models combine powerful suction with aeration to provide:
Enhanced debris removal – improves extraction of waste from the pond floor by up to 30% compared to standard models
Increased oxygenation – boosts dissolved oxygen levels for healthier fish and beneficial bacteria
Gas release – helps release harmful gases trapped at the pond base
Improved water circulation – ensures consistent cleaning and oxygen distribution
Aerated models are engineered for high-efficiency aeration, creating a cleaner, clearer, and healthier pond ecosystem.

The AQUA SURE Weighted Suction Dome Range works with gravity-fed and pump-fed filtration systems, making it suitable for almost any pond setup.
Gravity-Fed Systems
Preferred for maintaining solid waste
Debris flows naturally into the filter, preventing pump shredding
Best for 110mm models
Pump-Fed Systems
Standard domes integrate easily into pump-fed systems
Supplied with fittings for:
43mm / 1.5” (40mm Domestic Waste)
56mm / 2” (50mm Domestic Waste)
Two stepped hosetails compatible with most flexi hoses (up to 50mm ID)
110mm models – designed for gravity-fed systems; allow higher flow rates and smooth debris transfer
Standard domes – compatible with both systems, ideal for pump-fed setups
