Guys, per Isg's response:

4 bottles are used because of the tank's dimension. Also, the choices of plants used, some of which are high light plants which have greater needs of CO2.

The basic CO2 recipe used is sugar+yeast+baking powder

The air tubing used is that of "PU type pneumatic parts form factory use",which you can find at any hardware store that carries electric hardwares.

So far so good; no leakage.


And this is his reason for using DIY CO2, even though everything else is pretty high-tech:
"I like to try using DIY CO2 because I have heard from others before that it cannot grow plants well. I wanted to do this as an experiment to see what happens."
