15' x 42" Intex metal frame here. The included 1000 gph cartridge pump is completely inadequate, so it's time to upgrade.
Is the 2650gph sand filter going to be overkill? Or should I just get the 1500gph sand unit? Is one of these easier to install than the other? Do these pumps include shutoff valves? Do they include adapters to use the existing hoses, strainer, and return?
