Running a valve on the drain is a very dangerous way to regulate flow or noise, snail goes down his drain = flood, valves starts to gather crap, clumps of algae = flood, fish goes down the drain = flood, and it will happen eventually. It's always best to regulate flow on the return side.

ahah that's exactly why I said he was crazy in the first post... UNLESS you have a back up drain. I don't think he's try to "regulate flow" to the tank he just trying to reduce noise and bubbles like he mentioned in his first post which is why he is trying to control the out flow to reduce the air in the line which is why he needs a herbie style drain

He could try a few other methods... but the ball valve would seem to indicate that he's leaning toward a herbie?? Which is the quietest
