I have a 2500 gallon swim spa pool with a 3/4 hp pump situated about 45 feet from the pool. Would this filter be adequate?

A  Answered on 7/31/2019 by InyoPools Product Specialist Matt S.

The safer bet would be the Hayward Star Clear Cartridge Filter 50 Sq Ft. 1 1/2 Inch Ports - C500. Besides the flow rate, the larger the filter, the longer you can go between cleanings. If you go with the C250, that is potentially twice the cleanings per season.

What HP is the C250 Filter? Will it vacuum a pool? Does the filter have a leaf trap?

A  Answered on 11/21/2017 by InyoPools Product Specialist Lennox H.

Hi. This Hayward Star Clear Filter - C250 flow rating is 25 GPM max. It has the capacity to vacuum a small pool but, debris capacity is 25 sqft. It does not have a separate leaf trap but will filter leaves.

will this or one of your other filters reduce calcium deposits

A  Answered on 6/24/2017 by InyoPools Product Specialist Lennox H.

Hi, Mike. There is not a filter that will reduce calcium deposits, you'll have to keep your water chemistry balanced.

how too remove cartridge

A  Answered on 7/15/2016 by InyoPools Product Specialist Alan M.

Removing the cartridge is quite ease. There is a star shaped knob on the top of the filter that you would need to unscrew and remove the lid. This will grant you access to the cartridge inside the filter.

I have an above ground 12'dia pool. Would I need a 25sq ft or 50sq ft coverage? Thanks, Dave

A  Answered on 6/5/2016 by InyoPools Product Specialist Lennox H.

Hi Dave, The flow rate of your pump would determine the size filter. FYI, the bigger the filter the better.

?     Asked on 10/1/2014 by Guest

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.
