Kalk King is an exciting new automated Kalkwasser dosing system by E-Fins, who you might recall from the Algae Mower Vac. We thoroughly covered the workings of the Kalk King, but E-Fins just released a video with an overview of their automated kalkwasser doser in the case you are more of a visual person. The video does a great job of highlighting the systems many features, including many fail guards to prevent the unthinkable from happening.
Some of the fail guards of the Kalk King include a large outflow to prevent clogging, the use of a constant pH monitor to prevent spikes and dose fresh water instead of kalkwasser if necessary, and low flow rates in case all else fails. Additionally the fresh water input into the kalkwasser reservoir is mounted above the water level to prevent kalkwasser from siphoning into your fresh water supply. It should be mentioned that the Kalk King also features an alarm in the case the float switch gets stuck, although the feature is not seen in the video.
The Kalk King appears to be incredibly easy to use, and should be “set and forget” once the basic conditions such as desired pH and drip rate are calibrated. With a set retail price of $299 the system furthermore is quite affordable considering all the accessories included.
