I currently have a DE filter and a 3/4hp Hayward super pump and would like to replace the filter with the C900 Hayward cartridge filter will the pump be able to handle the filter?

A     Answered on 6/21/2018 by InyoPools Product Specialist Hector F.

It may be enough but I would recommend going with a c1200 filter to be safe providing a little more filter and pressure capacity.

What is the measurement from inlet port to output port? I am replacing an older smaller Hayward filter and want to kow if it will fit in the same space.

A     Answered on 2/9/2018 by InyoPools Product Specialist Lennox H.

Hi, Bill. That measurement is 13-1/8".

Hi, Paul. You can use this filter if the flow rate does not exceed 90 GPM.

sent an mail previously about this.replacing a hayward CX1250RE filter C1200 was recommended. physical space is an issue as it is too tall. would a C900 for for a small viking baja pool if filter is only about 15 ft from the pool 12' X 25' X 3'8"-5'6"- pool is under 9000 gallons.

A     Answered on 3/15/2017 by InyoPools Product Specialist Andy O.

Joe- You would have to make sure that your filter can handle the total output from your pump. As long as your pump doesn't exceed the maximum flow rate of the filter you should be good to go.

Up to what size pool is this filter good for; in other words how many gallons of water in the pool.

A     Answered on 2/13/2015 by InyoPools Product Specialist Robert M.

Hello Tony - In a perfect world this filter can handle 43,000 gallons. In reality, we would not recommend this filter for anything more than 20,000 gallons.

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.

Does this come with the filter cartridge and gauges?

A     Answered on 9/21/2006 by InyoPools Product Specialist Patrick P.

This filter comes direct from the manufacturer and includes the cartridge and gauges.
