New intex owner here and have been reading this site for the past 2 weeks. I have gained tons of info!!! I purchased a 15x48 Easy Set "blue blob" pool. Using the BBB method to try to keep chemical costs down and having clear water. Anyway after 9hrs of digging by hand with a shovel i have the ground pretty level, got the pool up and it's doing great. However i have a few questions. 1 the 1000 gph cartridge filter/pump is pretty much useless. I run it 24/7 and the water is cloudy. Having a pool party today and this pump will take a month with no pool use to clear the water up. So i plan on getting the intex sand filter. I just dont know which size to get the 1600 or 2650? My pool is roughly 3750 gallons. Any recommendations? I also plan to purchase the skooba vac and use the pump/filter for vacuuming rather than the vacuum that came with the pool. Last question. Can i install a through wall skimmer on this type of pool? if so what kind?
