Thanks, I will double check the pump size when I get home this afternoon.

This is my first year with the pool and we have just been getting it cleaned up. Silt does appear on the bottom after I vacuum, but I was assuming that it was just silt that I stirred up during my cleaning that just settled back down, rather than coming from the filter. I guess I could try the panty hose trick over a return to see if any silt is coming through the returns.

Is there any harm in operating at this pressure? I doubt I would replace it just to prevent some silt from channeling through unless there were some other reason.

I was also thinking of using some DE in my sand filter as suggested on this forum, but this would raise my pressure even more. Is that a bad idea?

Thanks.
