Arvin's 50g low boy frag tank

Got a diable skimmer (not sure what model) with a PSK600 pump. Trying it out on this tank for the time being. I put it on top of a spare frag rack to raise it up as it was just overflowing water if I had it on the bottom of the sump. Currently the water level is about 1in higher than the top of the pump. I have no experience with these old school skimmers so any advice would be great. Is it ok to extend the exit plumbing down to below the water line to quiet the exit water from just dropping out and falling back into my sump?
