It seems as though the hobbyist that are really into keeping SPS often times have a calcium reactor. To be honest It's very intimidating as a novice reef keeper to look underneath someone's tank and to see a calcium reactor sitting outside of their sump. The idea of plumbing to and from the reactor and possible floods have been enough to keep me from going this direction. Is there an insump calcium Reactor that doesn't need separate plumbing or a simpler version of the calcium Reactor?
