Koi Pond Bead Filters
Efficient Filtration. No Blower Required. Less Backwash Water.
High-efficiency polypropylene floating-bed bio media for superior biological filtration.
HydroBead™ Vortex koi pond filters are designed and engineered with a similar concept to Hydro Vortex™ waterfall filters with an internal water whirling vortex. Water enters parallel to the radius of the heavy duty fiberglass tank and swirls into a vortex. Centrifugal water motion causes heavy solids settle to the bottom. The water and any suspended particulates then flow up through the highly buoyant floating polypropylene HydroBeads™ and out the upper lateral.
HydroBead™ Vortex koi pond filters perform two roles: The first role is performing as a biological filter to metabolize fish's metabolic byproducts and ammonia into nitrate and nitrogen. This is known as the Nitrification Cycle and is performed by nitrifying bacteria living on the individual HydroBeads™. The second role is water polishing by way of micro-filtering. The highly buoyant polypropylene HydroBeads™ micro-filter out suspended solids for clean, clear koi pond water.
HydroBead™ Vortex koi pond filters feature the highest SSA (Specific Surface Area) in their class. The polypropylene HydroBeads™ have much higher surface area than other types of filter media. The HydroBeads™ cylindrical hollow and semi-hollow beads vary in size and work together for superior polishing within the tank. As the water flows upward, the suspended particulates get trapped in the bottom section of the bead pack. When water is reversed in Backwash mode, the downward flow of the water agitates the beads that want to float - this releases all the trapped particulates down and out of the filter. No air blower required!
The multi-port valve controls filtering, backwashing, and bypassing. In backwash mode, the water flow direction is reversed. Water flows out of the upper lateral into and through the highly buoyant HydroBeads™ and out through the bottom drain and lower lateral. The beads are highly buoyant and stay floating while the water is forced downward through them. Due to the upward flow design, backwashing doesn't require an air blower like those found on down flow koi pond filter designs.
