This is my new vacuum attachment return with pebble regulators. It was just a 1.5" straight pipe that didn't make much of a splash. I wanted more aeration and water noise so tried this and it's working fine for me. The fish love it too. With a higher volume pump and some pitch control I think a body could make a pretty dynamic fall. What can I say, I'm cheap.
Chrysalis,
Now that is a swell idea! That's ingenuity!
