We have a pool that's like an Intex but is sturdier and can be left up all year. We run a regular sandfilter to filter it. As I was reading through things to find out how to clear my cloudy water and high Ph levels. Since it's a vinyl type pool is it considered an Intex type or is it just an above ground type since it has a sand filter. I figure I need to know this in order to maintain it correctly. Also, we filled it with Michigan well water. We do have iron issue in the house. where the water drips in the bathtub, it is rusty colored. Please advise. Thanks.
