We currently have a Haywood S244S Sand Filter for our 28k gal pool and have come to the time where sand needs replaced and valve needs a rebuild and are thinking about changing to a cartridge filter. We have a new 3 HP variable speed programmable pump. I was thinking at least 425 sq ft filter or maybe larger. I was considering the Doheny 425 or 525 but haven't seen many reviews. I would consider any brand and welcome your advice and suggestions.
Thanks in advance
Steve
