Hows this for a trickle filter?

the pipe extending from the intake would be the overflow.

and...how am i beggin for trouble?
 
I think that would work out just fine. The chances of a bulkhead leaking are slim, and even if it does it will start as a small leak rather than a huge burst of water.

I think the Idea of running a PVC tube to the top will work just fine.
