I just started reading on this co2 thing a few months ago . Im confused every time i read more . You guys have suggestions for installing a setup like this on my 180? Also my ph is round 7 just where i need it . Whats going to happen exactly if i inject my tank . Can i adjust so that it doesnt make my gouramies upset . My tank is 2x2x6. Not trying to jack a thread . I like the sound of this setup yaw have going . Didnt want to confuse asking someplace else .
