I have a DIY calcium reactor built for my previous tank that I've now outgrown and was looking to sell. Been working beautifully for 2 years.
It's a dual up/down flow design (much like the BAR reactor), and uses a Mag 3 for the recirculating pump. Holds almost two jars of ARM media, has gas recirculation or can hold a pH probe for controlling CO2 injection.
Asking $100 for the pump and reactor. Does not include reactor media, CO2 tank or any other CO2 accessories (all those are in use on my current reactor)
Here's a thread I started when I first built the pump
