Since we decided to convert the 180g to an 'SPS tank', we also decided that a Calcium Reactor was what the doctor ordered.  Don had been researching them and taking notes, and bookmarking the best DIY sites for almost a year.  Our reactor is a combination of what we felt were all the best designs - basically combining the best features of a number of different calcium reactors.

The basics of the design came from  John J. Geisler's DIY Caclium Reactor plans .  Many thanks to him for answering so many of our questions!

The reactor is a dual-chambered, reverse-flow reactor.  The reverse flow allows for more contact time with the reactor media, and also prevents 'channeling'.  The reactor tubes are both 6" OD. and 18" tall.
