Are two filters better than one?

[mspool]

ummm I was wondering how this all turned out as I have the exact same problem with silt and fine dust coming back through the return jet when I vacuum. I am troubleshooting in another area of the forum but thought a reply here might yield a response from the person who started this thread.

I have same problem, but think it's from the street that runs parallel to my pool. It's about 15' from pool and separated by an 8' wooden fence. Problem is that it's a low spot where creek run goes behind my property and then under streets. Two streets actually, since it's a divided street and speed limit is 30. I think this because it collects on the coping--above ground pool.
Anyway, I'll try the DE thing, just to get better filtration. Also wondering how poolboy was doing w/ his problem.
