Hello everyone. I just bought our first pool this week (Intex Ultra Frame 22'x52") and am wondering what the usual upgrades are. The pool is still in the box and came with a 2500 GPH pump and canister filter, but I am planning on swapping this out for the Intex 3000 GPH Pump and Sand Filter. Is this a good setup? I was also thinking about going the saltwater route. Without getting into a Chevy/Ford type discussion, is this the more popular thing these days? Thanks everyone!
