So I have been running my pump for a bit over 2 weeks now due to water being a bit hazy and not crystal clear. I decided to buy a solar cover and installed it yesterday. This morning l look under and the pool is crystal clear. I think the magic clearing fairy lives under there but she does not want to be seen when he is doing work. I don't get it. Everything was balanced before and it still is but the water would pick up a slight murkiness. So maybe for some people out there that did it all and still are not happy with the water, try a solar cover. I was always against them thinking that will increase my chemical demand due to water temp being higher. Not true at all.
