good point on the turtles and birds...3000ft from a pretty major creek/swap isn't very far for them to bring in some junk.

I plan to do annual shock analysis so I guess I can combine my best filter efforts with shocking to remove unwanted species as best I can.

I'm still trying to find some commercially available filters...I can't believe nothing exists for this problem.
