Oh cool! thanks a lot. That will make it nearly impossible to build up air inside. So far I have tested it and there is still a good syphon after being not in use for 24 hours so I guess the air is not getting inside but I want to be safe!
I already have such pipe at the intake of my return pump so all I need to do is drill a small hole and glue a air tube like in your pic.

You could even just stick the airline tube into the intake (being careful that it doesn't get sucked into the impeller, and it will work. Many ways to do it...
But don't use an aqualifter or any air pump, becasue if it fails, you are hooped....
