We purchased an Intex Ultra Frame pool this past fall. It's the 14'x42" model. Of course it came with the cheap little cartridge filter. I am planning on purchasing a sand filter for it. My question is size. I know the 1200 and 1500 GPH pumps will handle it, but would there be a detriment to going with the 2650 GPH filter/pump? This is our first metal frame pool, and if it all goes well we plan to go larger down the road. With that I would prefer to buy the larger pump now as long as it is not going to cause issues with the smaller pool. From what I can tell if should be fine, and just would not need to run as long. What are your thoughts?
