The KHManager is a stand-alone, app-controlled device, which automatically samples and tests your tank water for pH and KH, then calculates and auto-doses a precise volume of KH solution using the built in stepper pump to maintain a constant alkalinity level within your aquarium.
Purchase of the optional E1 expansion box allows the KHManager to be linked with up to two D-D P4/P4 PRO 4 channel pumps and use the inbuilt software to provide automatic adjustments of the existing dosing schedules of one or more of the heads on those connected pumps, adjusting the dosing volume up or down relative to the measured KH demand.
In this way the KHManager simplifies the handling of multi element dosing, avoiding the gradual drift if one solution is adjusted in isolation and making it ideal for more complex solutions such as the Reef Zlements Complete or pHPlus 2 part dosing systems.
You can also connect a single Kamoer FX-STP to automatically adjust the speed of supply water to a calcium reactor.
Developed in partnership between D-D and Kamoer for the European market, the KHManager combines Kamoer’s experience in the manufacture of high precision medical grade dosing equipment, with D-D's knowledge and understanding of the specific requirements for control of the alkalinity within a modern reef aquarium.
The stepper motor-driven pump heads, precision pH probe, twin optical sensors, automatic stirring and flushing protocols are all important features that ensure each test sample is collected, tested and dosed with the greatest possible accuracy. Unexpected high or low readings, (out of trend), are automatically retested to safeguard against sample errors and user-defined limits alert against over or under dosing outside of set parameters.
