This is often due to incorrect use of the test. It is important to shake vigorously for exactly 1 minute. All other necessary steps are described in the instructions for use.

The tests from the test series: JBL GH Test, JBL KH Test, JBL Calcium Test Ca and JBL Magnesium Test Mg are so-called titration tests, in which the number of drops until the color change is counted and the counted value is multiplied by a value: GH = number of drops = total hardness in °dH KH = number of drops = carbonate hardness in °dH CO2 = number of drops * 2 = CO2 in mg/l Magnesium + calcium = number of drops * 120 = total Ca + Mg in mg/l Calcium = number of drops * 20 = total Ca in mg/l Magnesium = total Ca+Mg from magnesium test - total Ca in mg/l = magnesium in mg/l
With JBL PROAQUATEST drop tests, you have a laboratory comparator system that compensates for the natural coloration of the water and enables non-chemists to perform accurate and reliable water analysis. To ensure that water testing monitors the health of your fish and provides the greatest possible safety, you will find a customized evaluation for three different applications. Above the different colored measuring points are numbers, three symbols, and a colored band. The symbols represent the following areas of application: Fish = Freshwater Koi = Garden pond Starfish = Saltwater The color band indicates the meaning of the measured value in green (everything OK), yellow (caution) and red (action required). In addition, you will find numbers that indicate the value in mg/l for the respective color field. The first two color strips (freshwater and pond) belong to the upper row of numbers, while seawater belongs to the lower row. Why do the values differ? Due to the high salt concentration in seawater, the color of the reaction is not as intense as in freshwater (including ponds). Consequently, the value is higher than in freshwater for the same color. Why do the recommendations differ? Each habitat reacts differently to certain nutrient concentrations. In garden ponds, for example, constantly changing temperatures and light intensity can make the value more critical than in freshwater, where these factors are constant and necessary additives ensure balance, which are not added to ponds. Therefore, the recommendations are green for one area of application and yellow for another.
No, no tools are required and should not be used under any circumstances. Using a tool may cause damage. You can attach the pressure reducer to the CO2 cylinder with your hands. Turn it until you feel resistance and then turn it about half a turn further. The pressure regulator will then be securely in place. When attaching the regulator to disposable cylinders, you will hear a short hissing sound.
