The color charts are not available for download on the JBL website, as a color-calibrated printer is required to ensure accurate color reproduction, which is rarely the case in private households. You can find the color chart booklet as a spare part on the respective product page and in the spare parts shop at: https://www.jbl.de/de/produkte/detail/8732/jbl-proaquatest-sortiment-farbkarten
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.
The new PROAQUATEST O2 oxygen Each one contains 3 reagents instead of the previous 2 reagents. This means that the new color chart with red tones instead of beige tones must be used for color comparison.
