This same design has been around for decades BTW, PVC pipe was used for many a DIY breeder tank I've seen.

I depending how busy I am with work, I might be able to build a better version within the week. I'll keep this thread updated.
As for the picture in my car. I have some driveway moments when I want to finish listening to a radio broadcast. I'll usually fiddle with something at the same time.

Do you usually do aquarium work in your car? Lol
I'm having a hard time understanding how this will work so I'm looking forward to pictures of it up and running on your aquarium.

Good looking overflow siphon attempt
I have updated my overflow siphon. Here is what it looks like now:
It looks better in the water:
I decided to do away with a self priming venturi because it would spray bubbles into the tank every few seconds. It has run several days without any bubble accumulation, but i must admit I've only tested flow ranging from 100-150gph for extended periods.
I made the intake height and tank hook height adjustable with a nylon set screw. This lets me tweak the water level without excessive air being sucked down.
Here is my biggest change:
I took a lesson from dual stand pipes to completely eliminate the "glug glug" or toilet flush noise. I just close down the gate valve until the lower pipe no longer sucks any air.
You can hear how quiet it is here:
I am pretty happy with my results now and am going to look into putting it on a tank. I wish I could have made it a little more compact and keep the same flow capacity, but this is as tight as I could manage to push the bend radius of acrylic without creasing.
