I have a inground pool 32 x 17 about 22,000 gallons, and currently use a hayward super pump 1 hp. Will this filter work?

A  Answered on 7/16/2012 by InyoPools Product Specialist Patrick P.

Yes the Hayward C17502 Star Clear Plus filter would be a perfect companion to the 1 HP Hayward Super Pump.

Are there specs on how many microns this filter is rated at? Is there available another filter that won't allow finer particles to pass through?

A  Answered on 10/1/2014 by InyoPools Product Specialist Patrick P.

As a rule, sand filters sift particles ranging from 20 to 40 microns in size.  Cartridge filters can sift particles as small as 10 to 20 microns in size.  DE filters can sift contaminants as small as 1 to 3 microns in size. This makes DE filtration at least five to six times more efficient than sand filtration systems.

I have the Hayward 175 with double cartridge, My pool is 17,000 gallon, I have 2hp pump that is running through the cartridge. Do I need a double cartridge or will a single one be just fine

A  Answered on 3/23/2015 by InyoPools Product Specialist Robert M.

Hello Fitz - A single C1750 cartridge would be sufficient for your pool.
