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.

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 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 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 Patrick P.

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

 (5 out of 5 stars)  Hayward Pool Filter Replacement

from Tamap, FL ()

Pros: good construction; easy to install

Cons: poor documentation

I had to replace an older unit that began to leak. The new unit is very similar to the old deisign. Fortunately, the plumbing matched so installation was simplified. There is a new gauage and top cover design. There were no installation instructions or an explanation about the new gauage.

 (5 out of 5 stars)  Great spa cleaner

from Baltimore, Maryland ()

Pros: Does a good job.

Cons: Outlet higher then the old C500 filter and is at a higher level the the heater. It had to be repiped anyways so I put the heater on a piece of wood. Problem solved.

Replace the C500 filter with the 90 Sq. Ft. filter. Was undersized & couldn't handle the amount of water being pumped. This filter is larger then what is needed but is doing so much better of a job. Will think about getting a spare filter element in a few months. Also had to replace the heater, the gate on the return valve broke & blocked the flow. That split the first filter housing (the C500).
