D-D UltraFlow Weir Comb – High-Flow Overflow Comb for Aquariums

The D-D UltraFlow Weir Comb is engineered to significantly improve water movement through aquarium overflows. By incorporating an additional grid on the underside, the comb increases surface area and allows 30–40% more water flow compared to standard weir combs of the same length.

Designed for practicality and ease of maintenance, the UltraFlow Weir Comb can be quickly removed for cleaning and is compatible with a wide range of glass thicknesses. Its two-part system allows push-fit installation on standard weir glass or permanent bonding on thicker panels, making it a versatile upgrade for modern reef systems.
