Okay, there's a new brew your own beer shop in the city where I live and I was wondering if there were parts made for making your own beer that I could use to build a co2 system for planted tank injection. I've already boughten champagne yeast at this shop for my DIY yeast system and it's working incredible but it's time to step into pure co2 injection. My city doesn't have any shop dedicated to aquariums and this DIY beer shop is as close as I can find. Any pointers to building a system would be great. Any experience also. Thanks everyone!
