Alkalinity (KH) refers to the concentration of various negatively charged ionic compounds (such as carbonates, bicarbonates, borate and hydroxides) in aquarium water. Maintaining correct alkalinity levels in your aquarium is essential to keeping a stable marine environment. When the KH levels drop too low, the pH of your aquarium water can fluctuate wildly, causing stress and even death for your livestock. In marine aquariums, an alkalinity level between 7 and 10 dKH is recommended for keeping a stable pH. The Alkatronic makes it possible to easily monitor and adjust KH levels with little to no maintenance on your end, thus providing you with more time to enjoy your healthy, happy aquarium inhabitants.


The Alkatronic is an all-in-one standalone product designed to monitor and stabilize alkalinity levels in reef aquarium systems. The Alkatronic will automatically correct any KH deviations by dosing carbonates from its own dosing pump or by activating a Bluetooth Smart Outlet (not included)

As a completely standalone system, no additional dosing pump is required for operation; However, when paired with the Dosetronic 5-Channel Dosing System, the Alkatronic provides the additional functions of "Overall Dosing Adjustment" and "Selective Dosing Adjustment" to auto-adjust dosing channel(s) based on the dKH consumption of your reef system. The Dosetronic and Alkatronic even share the same footprint dimensions, so you can stack them on top of eachother for space-saving effecicency.
