I just installed a DIY CO2 canister using an aqua one 500L\H internal as a powerhead and i was just wondering how long i should wait for CO2 to be created\injected. Also am I better to put it on top or under my tank? Is CO2 Heavier or lighter then air, or doesn't it matter because it's under
pressure?
pressure?
