I have a 20 gallon long tank that is divided into 4 sections (for bettas) and is planted. I'd like to add CO2 but I don't know if it will work properly for a divided tank. The dividers are made out of plastic mesh canvas (the kind used for crafts) so they allow very good water circulation. Can I just put the diffuser in one of the divided sections or do I have to use 4 seperate systems?

Thanks in advace to anyone who can help! :)
IM pretty sure putting the co2 on one side you should be fine.if you have a filter running im not sure if you would want it near the filter so its pushed around the tank or on the other side so its pulled towards the filter. I f i had to guess i would say near the filter.
