I have a reef octopus CR100 calcium reactor setup I’m gonna be taking offline next week, I can include everything needed to run it including the reactor, a kamoer peristaltic pump, carbon doser regulator, and a nearly full 5lb c02 bottle. Also have a Neptune ph probe and pm1 I can include for extra $50 if you have an apex and some reborn and remag to fill the reactor with.
Basically everything you need and top of the line to get going. All equipment is no more than 3 months old. Looking for $600.
