I'm not sure I'm using the correct measure of DE when I reload my filter after a backwash. I'm using the 1lb 13oz blue plastic Maxwell coffee containers. My filter is a Pentair FNS Plus 36. How many containers of DE should I use on startup (after I have cleaned the filters at the start of the season) and how many after I backwash during the season?
I am seeing very tiny pieces of debris on top of the pool, and am worried that the filter is not loaded properly. Of course, the pool sits under a live oak, and there is constant material falling in especially during a rain storm or even mild winds.
thank you,
