co2 for a 5 gallon aquarium

[bgk]

i have a 5 gallon aquarium and i want to dose it with co2 i have a yeast system that will not put out 1 bubble per minute but do i need 1 bubble per minute for a small tank like this

Ask the plant guys rather, im sure they will be able to help.

I have done the yeast co2 thing in the past and it is a pain in the Ass, the results are not worth the effort imo.
