We purchased one of those Sand N Sun easy set vinyl pools from Walmart.
I've tested the water with the kit recommended on this site and the #'s were pretty good.
But we have some sort of sediment issue keeping the water cloudy and greenish brown (used well water) and my husband thinks our pump and filter isn't strong enough. I already super duper shocked it in case it was algae.
I don't know the pump size. But the manual says it pumps 2000 GPH and it's a 6100 gallon pool (18' X 48"). The filter cartridge is a 7 sq. ft -8"X 4 3/4" O.D. in size. Just looking at the intake area there is no doubt water is easily and heavily going into the filter.
Today I'll try to determine if we have a metal issue.
But my other job today is determine if the pump and filter are adequate before he spends more money that may not help our situation.
