My water is not in good shape right now. When I brushed it today all these mold particles came up and are floating around. Pretty disgusting. The walls feel all slimey (or at least did before I brushed). So a question that arises is - should I go to a sand filter? IF I stay with Biguanide, many people have told me that Biguanide and DE are not a great combination, and that sand works much better. Or...if I convert back to chlorine, I suppose the cloudy water issues will no longer be an issue? I started with chlorine many years ago and don't recall having any problems with slime, etc. nor cloudy water. I went to Baq after having so much trouble with chlorine demand, then never went back to chlorine. But I am getting pretty tired of the constant battle.
Thanks for any advice,
