KH keeper Q&A

The 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 run the device at your aquarium, you only need access to your home WiFi network, electricity, a mobile device (smartphone, tablet, computer or laptop) with the Smart reef application installed and our reagent solution.

You can place the 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.

To prepare the 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 keeper to function properly. The table below contains volumes of liquids used to prepare a set amount of solution.

The magnet included in the kit is used to reset the device. If you want to restore the device to factory settings, apply the magnet to the area marked “RESET” above the hoses plugs and hold for 5 seconds. After this time, the device turns off and restarts. This means that the device has been reset.
