The AquaBeadX2 is designed in such a way that all valves and internals of the filter are double that of a regular filter. At no time does each pump's water pathway get smaller than a 2" opening. Everything is double on this filter so that we maximize the flow potential of each pump. Everything is double on this filter except the price, you'll spend less money on 1 AquaBeadX2 than installing 2 individual filters.
The problem: Pond is 20 to 25 thousand gallons. You want to turn it over about every 2 hours. A 1/4 hp pump will put out about 5000 gallons an hour. This means you need two filter systems to accomplish this and stay with energy-efficient pumps or a giant pool pump moving 10,000 gallons an hour and costing you an arm and a leg in energy costs.
The Solution: AquaBeadX2
With this filter, you can run two 1/4 hp or two 1/3 hp pumps and only pull about 5 amps total with the 1/4 hp pumps or 7.6 amps total with the two 1/3 hp pumps.
