Healeys,
I had a problem like you are talking about last year, my numbers looked good but the water was cloudy, was suggested to me(on this forum)to use a dose of clarifier (it will clump the small particals together to make it easier to filter out) Well i tried this and in a day or two my water was crystal clear. So I would try this if I was you, unless one of the posters on here that are smarter then me,(which is most of them ) tells you i am nuts. Hope this helps
