may have already been done. i was tired of the output of my seaswirl blowing water over the front of my tank, so i cut the bottom threaded half of the elbow off as close as possible and in the bottom of the opening i cut a vee. now the water comes out in a spray from just below the surface to almost 90degrees downward. it almost seems to pulsate and it really improved my overall circulation. hope i explained that ok. i can post pictures in the near future.
