Every few years we usually get a new Intex brand pool (the pumps go out) but I'm having issues finding one over 40" this year. We were looking at a 48" Coleman metal frame pools, is this a reputable brand? I know the differences between a side skimmer and the ground pump but which works better? The one that comes with this is a 1500gph ground pump and it seems a bit dinky for the water capacity (4500-5000gals), would it be possible to spend around $150 on a decent pump upgrade or would it cost much more than that? We live in an extremely dry and dusty area and always seem to have cloudy water issues even though all the levels are good.
