Me too about 12 years ago, so that is why I did come up with the CO2 reactor for the DIY yeast method. It makes the most out of the CO2 you have. The venturi was an after thought, added since I had no plug for the powerhead.
The burp hole can also regulate the bubble chamber size to what ever user selected height desired.
In this manner, you stabilize the CO2 and you also plug the powerhead into the light timer to prevent excess at night.
The internal design I have on the site is very effective for DIY users(I was one for 10 years).
