I've got my overflow system outside testing and it's been running for 3 days straight. The only problem is the crap that builds up on the ABS pipe, the slits I cut. It captures everything. What can I do to solve that?

The slits on my PVC pipe are only 1/4 inch, but because they are long and many with the pipe in the horizontal position, never did have any clogging problems. But if you look closely at my pic, you will see an elbow on the end with an open end pointed upward. That is the emergency overflow, in case the slits do get clogged.
