We are currently leveling our backyard for an Intex 26 x 52. I am getting ahead of myself I know but would like some opinions/experience stories of the pump & filter that came with the pool when we bought it. It's a Krystal Clear model 633T. So we're going to have to buy a bunch of those filter cartridges since it says change that every two weeks. What I'd like to know is if this pump is ok or are there upgrades that we could consider. Maybe something in the sand filter line? I'm just curious about it.
