JBL Ammonium Test NH₄
Quick test to determine ammonium/ammonia content in freshwater/marine water aquariums and in ponds

  • Simple and reliable monitoring of the aquarium/pond water values. Checks the biological balance (bacterial activity) in freshwater and marine water
  • Laboratory comparator system to compensate any inherent water colouring: fill glass vials with sample water, add reagents to another vial, place vials in holder, read values on colour chart
  • When to use: for setting up a new freshwater aquarium: once a day. Initial setup with marine water: once a week. For use in case of fish diseases or fish deaths
  • Online Laboratory: free analysis and recommendations for the water values you have measured
  • Package contents: 1 quick test, Ammonium Test NH4. Contents for approx. 50 measurements. Incl. 3 reagents, 2 glass vials with screw cap, syringe, comparator block and colour scale. Refill reagents available separately

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?
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.

FAQ
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 homepage. For this a guaranteed true colour print is required, and you need a printer which can be re-calibrated before each printout. Most privately used printers are not accurate enough for this.

We will happily send you a new colour chart bundle with all individual colour charts for the JBL tests free of charge. Please forward the JBL customer service your address.

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 the following 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.

Her’s how in greater detail:
JBL GH test kit: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH.
JBL KH test kit: 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.

JBL NH4/NH3 Ammonium/Ammonia test kit, JBL NO2 Nitrite test kit, JBL Fe Iron test kit and JBL Cu Copper test kit:
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 test kit, JBL SiO2 Silicate test kit, JBL PO4 Phosphate sensitive test kit and JBL Mg Magnesium test kit 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

JBL PO4 Phosphate test kit 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

JBL K Kalium test kit:
7.5 ml sample + 7.5 ml dist. water: result X 2
3.75 ml sample + 12.25 ml dist. water: result X 5
1.5 ml sample + 14.5 ml dist. water: result X 10

not required

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

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

Does the JBL ammonium test NH4 measure only ammonium NH4+ or does it also measure ammonia NH3 ?

The JBL ammonium test NH4 measures both ammonium NH4+ and ammonia NH3.

Aquarium problems

Are you faced with algae problems or don’t your aquarium plants grow well? Is the water cloudy or are your fish ill? Don’t your water parameters correspond to your expectations? Our team of experts has thoroughly analysed the problems that occur in the aquatic field and offers you solutions which really work.

Optimising water values

Having the correct water values guarantees you a functioning and beautiful marine aquarium. We’ll show you how to get them.

Pond care

The different seasons (at least in Central Europe) require different care measures. Even in countries where there are no cold winters with minus degrees, factors like rainy seasons, dry seasons or perhaps a summer with particularly high temperatures all play a decisive role for the garden pond.
