RobertoFlow Drain Pipe

Our community members decided to give this a name 
http://forum.reefangel.com/viewtopic.php?p=42105#p42105
So, I decided to create a tutorial page, so we can find it easy for future reference
The problem:
I've tried all different versions of stand pipe and they all have something in common... You must inject air into the drain pipe to avoid full siphon. I doesn't matter which one you use. You will always end up with cascading noise, even if it is minimal and a lot of bubbles in your sump.
I only have one drain pipe, so I can't really use those full siphon version with 3 pipes.
The solution:
Use a Reef Angel coupled with a water level expansion and a Speedwave pump to control the flow of your drain based on the overflow water level, so you have a dead silent drain pipe
Don't mind the mess... Here is a video:

And here is the code I was using:
