Sand in pool?

[JenLM]

OK, thanks. I'll find some knee highs tomorrow.

I too have had deposits in the bottom of my pool, almost like dust, not dirt (it's real fine and vacuums up somewhat easy but sometimes takes a little scrubbing with the pool vac). Just this weekend I put a white knee high on my one return and found small spruce pine needles in it this morning (we have a spruce tree near the pool that the wind will blow this trash into it). Having the knee sock there seems to have lessened the amount of 'dirt' I am getting into the pool. I too replaced my sand this year but did it like the instructions said, filled the filter with water first (about half way) and then put in about 170 pounds of sand.
