Calcium Reactors and Accessories

I had grand plans to bring a Calcium Reactor online on my system, taking advantage of a deal too good to pass up on a GEO unit, only to set it aside to have invested in an Apex controller and later learn that the GEO unit is not wide enough to accommodate a Ph probe (great option if you don't want to use it with an inserted probe). So, I later invested in all of the parts for a solution that would work with an Apex controller and have now since decided I'm going to stick with my kalk osmolater and if needed, supplement with 2-part dosing.

So, I have available:
