Once you put a proper vented durso in the back, this problem may just correct itself though.
I agree. The cross-sectional area of all those holes in the pipe is clearly much, much greater than that of the 3/4" bulkhead - yet the pipe is still under water. Vent or no vent, you either have to increase the size of the bulkhead, add a second bulkhead, or cut down on the flow rate of your return pump (probably by 1/2).
