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
