Its time to scrap the Jandy CL580 cartridge filter. My pool is right at 20,000 gallons with a Jandy stealth 2.0 HP pump. My pool is subject to lots of dust and debris as I have a field behind my house. Also my dogs swim everyday of the year so dog hair is a concern as well. I am looking for some recommendations on a sand and DE filter that will keep my water sparkly clean without for the years to come.
