Just registered, but have visited as a guest quite often, so I appreciate the collective knowledge on this board (side note, you guys were life savers in helping convince me to convert from Baquicil to the BBB model). I wanted to run this past those more knowledgeable than myself just to make sure my thinking is OK before I put in the order. I've got a ~13,500 gallon inground pool. Currently I have a Hayward Super II 3/4hp pump with an ancient sand filter. Both leak quite a bit and so I wanted to replace them both and switch over to a cartridge filter. I was looking to do another Hayward Super II, but the 1hp model (1.5" piping) paired with a Hayward 175 Sq.Ft. Star-Clear Plus Filter. Does that seem like a combo that will work? My skimmer/return lines are all 1.5", so I'm looking to keep all the plumbing at that diameter. Thanks!
