For sale CARBON DOSER ( CarbonDoser ) with REGULATOR and Tubing

I’m selling my Carbon Doser (CarbonDoser) with Regulator, 8+ Feet of Silicone Tubing, and 2 sets of quick hose clamps (2 sizes included). If connecting this to a Calcium Reactor, as I used it, you will need a check valve between the CO2 line from the Carbon Doser into the Calcium Reactor to prevent back flow into the Carbon Doser.

$20 shipping to the contiguous 48 states. If located in Alaska or Hawaii, please contact me to work something out.

Thank you for looking
