The pics were actually before my start up.
If you can find a piece of PVC
pipe (or the plastic plumbing from Lowes/Home Depot plumbing dept) that fits in the white collar, then drill some holes or cut some slots in it. You can then purchase a foam sleeve from an LFS
and slide it onto the pipe. I could not find a foam sleeve when I ran a wet dry so I took a square piece of foam and sandwiched it between two squares black plastic gutter guard (basically semi rigid plastic mesh), secured it with a rubber band and used that as a prefilter. I would rinse it out in tap water every few days to help prevent buildup and decay of waste material.
The second prefilter is not a bad thing to have. It was messy to clean because of its size.
