What Calcium Reactor

[spectra]

Putting together a 48x30x16 roughly 100 gallons and have a 40 breeder for the sump. So roughly 125 gallons lets say. What is the one calcium reactor people recommend and why? I though about running a doser but why......

Thanks!

I've only got experience with one, the Geo CR618. After months and months of product reviews and research that's what I settled on based on craftsmanship, ease of use, and value. Lacks a few bells and whistles, but hand crafted under amazing scrutiny and quality materials. Super easy to use.

MTC makes a comparable product but the wait time is atrocious, if you can even still get them new.
