Calcium reactors which to choose?

[DrAsTiC]

I have never used a calcium reactor so I am leaning on people who have hands on advice with these reactors. Which one would you choose?

Vertex RX4 Calcium Reactor
GEO 418 Calcium Reactor
Reef Octopus CR-140 Reverse Flow Calcium Reactor

I helped out a friend to choose a reactor out of all me research it came down to a geo reactor or mtc pro cal reactor. He chose the geo reactor. I will be purchasing one my self

MTC Pro Cal. Great reactor and great customer service.

To me, they all work fine as long as the basic principle is there where there is a down flow through the media, injection of Co2 mixed inline with the recirculating pump. C02 bubble glass is redundant since you would have one on your regulator and having a PH probe port is convenient so that you don't need to measure the effluent in a cup setup.
I just use a K2R CaRx (discontinued), simple and been working fine for the past 8 yrs.
