So I'm not a newbie LOL that's what we all think right? Anyways I'm upgrading from a 55 to a 150. Trouble is I can't fill the tank very fast with rodi water. Has anyone just used tap water run through the sediment and carbon filter (not RO) to fill large tanks? I'm moving so it has to be done rather quick. And making the rodi water is not happening quick enough! Lol. Let me know how you filled your tanks!
