Thanks.  I've been trying to come up with a design for doing an ultra low flow system for power conservation.  I like your idea.  I have a few tricks up my sleeve I've been working on.

I have it dump right in the bell siphon gravel guard. Water flow is split so a small amount goes to the tipper to kick the siphon. The main water flow is at the other end filling the bed. Works like clockwork on the small unit.  I thought the same thing you did at first.  The media would baffle the input from the tipper anywhere else in the system. But dropping it right in the gravel guard gives it a good rush. Splitting the input to the bed and tipper makes sure the nutrients get distributed well.

Hi Rick, I was curious to know if you have this working in a full sized growbed?  I would be concerned that when it tips, that the would not be enough level change to kick-start the siphon (at least with the low flow).  I've found with my low-flow siphons, that it was best to have a trap under the unit (most people just run the pipe right out or just have a 90 degree elbow),  the air gets caught in the standpipe/trap and creates little burps when the water is rising in the bell, which is enough to get a rush of water to flow out of it during one of the burps.

Hi Rick,

Can you please add/send me some still pictures? I can't get you tube stuff.

No problem.  It works really well.
