CAL Labs makes something like this out of glass, works very well for smaller systems like 160gph or less with no head flow loss.

Note, this method is based on the CO2 mist theory and these products and several DIY designs all came from the original hypothesis I proposed.
But many still do not believe the affect is real.
Rather than belief, I used an O2 meter, it's real alright, the details still need work and test, but the basics: does it work and does it make things easier to grow?
Definitely.
You may also use the CO2 mist method to determine if a particular species of plant is CO2 limited or not in the tank.
Simply blast the CO2 mist directly on the plant from a distance where the mist gently bathes/covers the plant with CO2 mist.
That, plus non limiting nutrients, you can generally grow anything and then vary the light as the independent variable.
Greg Fisk also did a similar thing as Anti P about a year ago after wondering about adding a venturi.
This disc approach is great for smaller systems IME and removes all the glass disc out of the tank where it gets covered by algae and also is just more stuff in the tank.
I bet we will see ADA make something like this later.
