i saw a guy who had 2,1 in each corner and it works really well does he just split the tubing to go to each diffuser?

and how long will a 5lb CO2 cyliner last in a 60 gallon?i am thinking about just getting a 20lb if i have to refill the 5 a lot



Sine my current ligh is only 40 watts and i need at least 2wpg to grow plants well and am probly going to get CO2 injections do you think i should buy this light fixture?
