I've had my calcium reactor setup for almost a year and have yet to fill the Co2 or the aragonite. My reactor is running kinda low, so anytime now I'm gunna refill it. But I still have half a bottle of aragonite and half a bottle of neo mag. My tank doesn't consume that much since all my stuff is frags. I love my reactor. Once u understand a calcium reactor, it's just too easy!
