Trade - Doser for Ca Reactor - Calgary
I have a very lightly used GHL 4 pump dosing unit (not stand alone) that I'd like to consider trading for a calcium reactor package. I would add cash depending on the value of the package.
The dosing unit works flawlessly but I'd like to go back to the Ca reactor. Only two four pumps have ever been used and only been running for a few months. I do not require a pH controller but ideally looking for the reactor with CO2 tank and solenoid.
