GLA Pro-2 CO2 Regulator with 2 block manifold and two atomizers

Description

This is for a GLA Pro-2 CO2 Regulator with 2 block manifold. I'm also including the two (2) atomizers and one (1) atomizer suction cup holder, both pictured. I'll also throw in some CO2 tubing that's been sitting in my cabinet (not shown). Setup instructions are included.
You can read more about the regulator from the manufacturer's website:

This has been used for about 4 years without any malfunction or issue. The manifold is modular so you can add or subtract lines as needed. It's currently set up for 2 lines but you can only use one of them if you like. Each line is independently controlled and has built-in check valves and bubble counters.
Here are the highlights from the company's website.
