Product information

Healthy aquarium/healthy pond with conditions close to nature
The right water values are dependent on the fish stock and the plants in the aquarium/pond. Even if the water looks clear it can be contaminated. With bad values diseases or algae can appear in the aquarium/pond. To maintain a healthy aquarium/pond with conditions close to nature it is important to check and adapt the water values regularly.

For each water analysis JBL provides water tests in the form of quick tests or colour change tests. These determine a certain value or several values in one go. With these water tests you can recognise algae problems and negative nitrate, nitrite, potassium, magnesium values etc.

Why test?
Nitrate is the end product of mineralisation in the aquarium/pond. Even in relatively high concentrations it is non-toxic for fish, but has an adverse effect on plant growth and the well-being of several fish species. Furthermore too high nitrate contents promote unwanted algae growth if phosphate is present in the water as well as nitrate.

Recommended nitrate values:
Freshwater aquarium (community aquarium): 0-50 mg/l
Lake Malawi/Lake Tanganyika aquarium: 0-50 mg/l
Plant aquarium with few fish (aquascaping): 10-30 mg/l
Marine aquarium: 0-20 mg/l
Pond: 0-10 mg/l.

You can analyse the water values you have measured in the JBL Online Laboratory free of charge and receive recommendations.

FAQ
Unequal consumption of individual water test reagents

The liquids of one reagent are empty, the powder is still half-filled. Can't you just buy individual bottles? No, because the JBL refill packs always contain all the reagents as a set and need to be replaced together. There is a reason for this. The reagents age when they are first opened and should therefore be disposed of completely as soon as one of the reagent bottles is empty. The unequal consumption is due to the fact that some test procedures require an individual number of drops, depending on the existing value in the aquarium water. So one needs more, the other less. The liquids can be emptied completely. In the case of powder, you cannot use the quantity you need if there is only a residual amount left. Thus the quantity is on the generous side, so that the range is ensured even with low liquid consumption.

Where can I find the record sheets for the documentation of my water analysis?

Have you lost your record sheets, used them all up, or need them in another language?
In the appendix of this FAQ you will find PDF files for printing them out in German, English and French.

Why are there different recommendations and values on the colour chart of the water test?

With the JBL PROAQUATEST drop tests you have a laboratory comparator system which compensates the inherent colouration of the water and at the same time enables non-chemists to carry out an accurate and safe water analysis. To ensure that water testing monitors the life of your fish and provides the greatest possible safety, you will find an evaluation adaptable to three different applications.

Above the different coloured measuring points are numbers, three symbols and a colour band for each.

The symbols stand for the following applications:
Fish = freshwater
Koi = garden pond
Starfish = marine water

The colour band tells you the meaning of the value determined in green (everything OK), yellow (attention) and red (need for action). In addition you will find numbers that reflect the value in mg/l for the respective colour field.

The first two (freshwater and pond) colour bands belong to the upper number row. Marine water belongs to the lower number row.

Why do the values differ?
Due to the high salt concentration in marine water, the colouring of the reaction is not as intense as in freshwater (which also includes pond). Consequently, the value for the same colouration is greater than in freshwater

Why do the recommendations differ?
Every habitat reacts differently to certain nutrient concentrations. In the garden pond, for example, constantly changing temperatures and light intensity can jeopardise the value more than in freshwater, where, unlike in the pond, these factors are constant and necessary additives are supplied. That’s why the recommendations are green for one area of application, yet yellow for the other.

I have lost my colour chart. Can I download the colour chart for the test?

The colour cards are not available for download on the JBL website. The absolutely accurate colour reproduction that is required can only be achieved using a printer which can be re-calibrated before each printout. Most privately used printers are not accurate enough for this.

You will find the colour chart bundle as a spare part on the respective product page and in the spare parts shop under: https://www.jbl.de/en/products/detail/8732/jbl-proaquatest-assortiment-color-chart

My nitrate test indicates measurement results which I can’t read or which are far too low.

The reason is often an incorrect use of the test. It is important to shake the test vigorously for precisely one minute. All the other important steps can be read in the instructions.
