Hi, I have an Intex 12 x 24 x 52 pool. 8400 gals.w/ saltwater. It is less than 90 days old and the pump equipment has been replaced twice. We have decided to replace the pump equip, but not sure which brand is good or bad. We have had enough BAD with Intex. Also I would like to hard plum the new system but don't where to start. Any help would be appreciated. Thanks...
