You are looking at the most technologically advanced pond filter on the market. The Pinnacle Filter's BY FLUIDATS concept was conceived due to the need for a filter that would allow the owner of a large pond to be able to filter it without the use of high energy consumption pumps.
The design of the Pinnacle Filter is such that you can use 2 energy saving pumps instead of 1 large high energy pump. For instance, some ¼ hp pumps only use 2.5 amps @ 115 volts. This means that you can filter a 20,000-25,000 gallon pond and use only 5 amps. No other filter made can make these claims
