Hi, I have a 24' x52" rough Douboy pool with sand filter and would like to put a larger cartridge filter on it but every filter I am finding that is 200 sq ft or bigger has 2" ports when everything on the pool is 1.5" and the hoses are slip fit with clamps. Does anyone know of a filter 200 sq ft or bigger that will work with the 1.5" slip on hoses with clamps or of any connector that will reduce 2" port on filter to 1.5" clamp on hoses? Thank you
