The color charts are designed for use with the comparator block. When using the comparator block with the blind water sample, any self-coloring of the water is compensated for. Without using the comparator block, deviations in the reading are therefore to be expected.
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 liquids in one reagent are empty, but the powder is still half full. Can I just buy individual bottles? No, because JBL refill packs always contain all reagents as a set and should be replaced together. There is a reason for this. The reagents age when first opened and should therefore be disposed of completely as soon as one of the reagent bottles is empty. The uneven consumption is due to the fact that some test procedures require an individual number of drops, depending on the value present in the aquarium water. So some need more, others less. The liquids can be emptied completely. With the powder, you cannot remove the required amount if there is only a small amount left at the bottom. The quantity is therefore slightly more generous to ensure that the range is equally guaranteed even with low liquid consumption.
A value of > 6 mg/l obtained in the silicate test means that more than 6 mg/l of silicates are present in the water. It is not possible to determine how much more silicate is present. It could be 10, 50 or even more mg/l of silicates. In many regions, tap water today contains silicate levels of more than 40 mg/l. More detailed information can be obtained from your water supplier or by diluting the water to be measured with silicate-free water, e.g. double-distilled water, before measuring. If osmosis water is used for dilution, the silicate content must also be determined. JBL Osmose 120 produces a permeate with 0.4 - 1.2 mg/l silicate from 40 mg/l silicate in the source water. With such high silicate values, the reducing effect of JBL SilikatEx can only be verified by diluting the water to be measured accordingly. 500 g of JBL SilikatEx binds approx. 5000 mg of silicate from the water. 400 g of JBL SilikatEx Rapid binds approx. 12000 mg of silicate from the water. Calculation example: 100 l aquarium with silicate in the initial water 50 mg/l: 100 l x 50 mg/l = 5,000 mg silicate.

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.
