The kH KH Keeper measures water from the aquarium. If kH drops too quickly between measurements the device will repeat the test and if the result is confirmed will send a notification to the user. An aquarist can set a value in the measurement difference. The tested water can be returned to the aquarium or go to the waste container, depending on user preferences. Everything is controlled by the Smart Reef application and can be connected with our other devices.

To prepare solution You will need RO water. For every 1 unit of reagent You will need 9 units of RO water. Remember to use precise amounts of each liquid for the mixture as it is very important for kH KH Keeper to function properly. Table below contains volumes of liquids used to prepare set amount of solution.

You can place the kH KH Keeper wherever you want , so that it has access by the hoses to the aquarium, water waste and reagent solution. The device is designed in such a way that you can place it in a visible place or hang it on the wall.

The small pill inside the measuring cup is a magnetic stirrer which that is mixing the reagent solution with water from the aquarium. Please pay attention and don't lose it.

Please see below our video tutorial on how to correct assembly mount and disassembly dismount the glass beaker.

kH KH Keeper can make corrections using the connected dosing pump. This function allows the precise control of the KH parameter to the level determined. It will soon work also with calcium reactors and 3rd party pumps via Power Switcher.

It’s very important to keep close measure over the reagent doses and because we want to you to achive achieve precise results when you are using your kH KH Keeper we’ve choose chosen a special motor for our reagent pump. It’s a step motor which is much more precise than a regular one. However, they tend to make more noise than regular pumps.
It’s perfectly normal for them to work louder than other pumps. Pump The pump should work more and more quietly as the time goes.
