Finally we are upgrading to an Intex 3000gph pump and sand filter. Will be delivered tomorrow! Im as excited as a kid on christmas morning. I might just skip out of work early to go home and tinker with it. Amazon had it on sale for $158. Right now Ive spent just about that on the "B" style cartridge filters already and now coming to the end of summer even those are getting next to impossible to find. So by the end of this year and part way into next season it will already pay for itself.
