Re: CO2 setup
No, not really.
Reason: mainly links that many other folks have as well as many books already have laid out for you.
There are dozens of links to various different CO2 set ups.
I use a gas tank, regulator, needle valve, sometimes: bubble counter, Check valve.
For the lines, I use silicone tubing or the tygon tubing.
Forn the reactor/diffusion, I use an internal venturi like on the site here, and external reactor(I make these myself), or a mist method.
I use a solenoid tio turn the CO2 off at night in most cases, I never leave CO2 on at night.
