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?
The degradation or mineralisation process of all organic substances in the aquarium and pond follows these stages: proteins > ammonium > nitrite > nitrate. By measuring these stages conclusions can be drawn about the “functioning” of the systems aquarium and pond. If the ammonium or nitrite level is too high it can lead to disturbances of the bacterial balance. Ammonium is not usually measurable in a maintained aquarium with an effective biological filter and in a correctly set up garden pond. Ammonium is an important plant nutrient and normally non-toxic for fish. But depending on the pH value ammonia, which is toxic for fish, can be formed from the ammonium ion.

Recommended ammonium values:
Freshwater aquarium (community aquarium): < 0.25 mg/l
Lake Malawi/Lake Tanganyika aquarium: < 0.25 mg/l
Plant aquarium with few fish (aquascaping): < 0.25 mg/l
Marine aquarium: 0-0.25 mg/l
Pond: <0.1 mg/l.

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

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

Have you lost your record sheets, already filled them all in or do you need them in another language?
With the following links you can quickly and easily print out your new record sheets with recommendations for the individual parameters at home and document the water analyses.

Which of the three scales on the colour cards symbolize of the water tests saltwater, freshwater and garden pond ?

koi carp = garden pond
angel fish = saltwater
discus = freshwater

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

The instructions point out that the comparator block should be used to compare the colours. Can this be done without the comparator block as well ? Or is there a factor from this comparison that is required for the measurement ?

The colour charts are intended to be used with the comparator block. In addition, when the comparator block is used with the blank water sample, this compensates the inherent water colour.

Therefore, if the comparator block is not used, there will most likely be deviations in the readings.

Does the NH4 test determine ammonia as well?

The JBL PROAQUATEST NH4 Ammonium has a chemical reaction designed to indicate both NH4+ and NH3 (ammonia) in the dye.

How much of the measured NH4+ value is then actually present in the user's aquarium in the form of NH3 depends on the pH value in the aquarium. The correlation between the value measured and the pH value can be seen in the table printed in the instructions for use.

Which scale applies for my aquarium? My test has two or three control fields with fish and recommendations.

We repeatedly receive questions regarding the symbols on the water test. The hobby areas cannot be clearly assigned to the scales for analysis. There are three symbols to make the hobby areas on the colour charts clear:

Discus = fresh water
Emperor = salt water
Koi = garden pond

In the following, you will find a list which assigns the scale for analysing the results from measurements in the hobby area and explains the symbols: The scales are described from the top to the bottom here.

NO3: salt water, fresh water, garden pond
pH 6.0 – 7.6: fresh water, garden ponds
pH 7.4 – 9.0: salt water, fresh water, garden pond
Fe: fresh water, garden pond

The following JBL tests have a uniform scale for all 2 or 3 hobby areas for analysis of the results from the measurements, as differentiation is no longer necessary:

SiO2
Cu
NH4
NO2
PO4
pH 3-10
O2

The JBL Ammonium/Ammonia Test (NH₄/NH₃) does not turn green, and instead turns black.

This JBL Ammonium/Ammonia Test expired many years ago and will not function anymore.

What can I do when the measured value of a water test falls outside the scale?

If one of your measurements reaches the end of the colour chart scale you can multiply the scale by diluting later tests with distilled water (e.g. JBL Dest).

Here’s how to do it: dilute the sample with distilled water and carry out the test once more.

This works in detail as follows:
GH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH.
KH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH.

Note: when using 10 ml sample water the colour development is weaker with the first drops than with 5 ml sample water. Put the measuring container on a white underlay for a better readability.

NH4/NH3 ammonium/ammonia, NO2 nitrite, Fe iron and Cu copper:
2.5 ml sample + 2.5 ml dist. water: result times 2
1 ml sample + 4 ml dist. water: result times 5
0.5 ml sample + 4.5 ml dist. water: result times 10

NO3 nitrate, SiO2 silicate, PO4 phosphate sensitive and Mg magnesium freshwater:
5 ml sample + 5 ml dist. water: result x 2
2 ml sample + 8 ml dist. water: result x 5
1 ml sample + 9 ml dist. water: result x 10

PO4 phosphate koi high range:
2.5 ml sample + 2.5 ml dist. water: result x 2
1 ml sample + 4 ml dist. water: result x 5

K potassium:
7.5 ml sample + 7.5 ml dist. water: result x 2
3 ml sample + 12 ml dist. water: result x 5
1.5 ml sample + 13.5 ml dist. water: result x 10

K potassium in marine water:
1. Fill 10 ml of sample water with distilled water to 300 ml.
2. Follow the instructions for fresh water.
3. Multiply the test result by a factor of 30.

CO2 direct, Ca calcium and Mg+Ca magnesium+calcium: not required.

What is the shelf life of the JBL Ammonium/Ammonia Test ?

The JBL ammonium/ammonia test has a shelf life of 2 years in the original sealed bottle.

The following is printed on the bottom of the packaging:

CH/B: 2246 (e.g.) = batch number
BBD: 05/12 (e.g.) = best-before date.

Please note that the best-before date does not apply for opened reagents. Exposure to atmospheric oxygen decreases the shelf life.

Do my water tests still work although they have been open for nine months?

Basically a sealed test keeps longer than an open one. How much the shelf life is reduced depends crucially on the handling and the storage conditions of the reagents. It may happen that a reagent in a test that has been open for 9 months doesn’t indicate correctly any more. However, additional information is needed to answer this question properly.
