Just to clarify things a little. I have not installed the Hayward Ecostar Vari-speed pump yet. I have a brand new one, a salt water system, and a new hayward sand filter. I wanted to get the pool all clean, before installing the new stuff. I am currently running a 3/4 hp Hayward super pump with the OLD sand filter.

I added the flocculant again this afternoon right before dark. Now that it is dark, when I turn my underwater light on, the water looks like it has millions of tiny snowflakes floating around in it. The problem is, is that it is not sinking.

Every time I vacuum though, I am getting lots of slime in both my skimmer and pre-pump filter. As I said earlier, I am still using the old sand filter, which is probably about 10 yrs old. I think I might should change out the sand, and see if that will help it catch more of the slime.

What you think?
