Anyone ever tried bbq equipment on a reef tank?

I just finished a wavemaker experiment with so/so results for a small (20G) tank. It might work better with a larger tank. I attached about 8 inches of larger thin walled surgical tubing I found in my friends workshop (still in sealed bag) to a powerhead outlet. It would whip around pretty good, but was unpredicable and blew in undesirable directions sometimes. Any shorter and it wouldn't move much. It was a fun experiment though.
