DIY Protein Skimmer
by Joseph Sellinger

This is a counter-current protein skimmer. It requires an air pump to power it.

The hardware, excluding the air and water pump, was purchased at a local hardware store for approximately $50. All of the PVC is SCH 40 and was glued together by non-toxic PVC glue.

To use the skimmer, drill a hole in the 4" PVC cap and run some rid glue airline through it. Connect a wooden air stone to one end, and an air pump to the other. Two air pumps may be neccessary.

The water in and water out valves are approximately 40" from the ground, and the 3/4" PVC is used inside the 4" PVC.

The water return in the skimmer is cut approximately 2" above the bottom of the skimmer. The toilet flange should be attached to a piece of wood to keep the skimmer from falling.
