I purchased a Summer Waves pool this year and it has the sidewall skimmer/filter. I want to use my existing Intex sand filter. This pools skimmer/filter is different from the Summer Escapes that I have seen posted. Has anyone converted a Summer Waves to a sand filter? I'm sure my husband and I can muddle through, but would rather check to see if anyone has any advice. The model number on my pool is P4001648B138.
