Well I saw some guy that had just a little dome thing that caught co2
and then it disolved but had nothing else with it so I tried it with a bottle and all it do was filled up the bottle with co2
and then made it float to the top.
I'm confused what to do you guys know what i'm doing? By the way I don't have a power head thing to do the other DIY diffuser so try to keep it simple for me please.
