GHL Doser 2.1 Standalone version in great shape. Used since October 2017 to dose 10ml a day of Triton on the first 3 dosers and the 4th has dosed aminos or vinegar between 10 and 20ml a day. I purchased this from AquaCave in October 2017 and it comes with a 2-year warranty. Provide me an email address and I will send the original invoice in case you need to contact GHL for support.
Moving to a calcium reactor and this is not needed anymore. I don't have the original box. Price includes shipping anywhere in the lower 48 states.
