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 well-being of aquarium and pond dwellers and the growth of aquatic plants depend to a large extent on the pH level being kept as constant as possible. The pH level can also affect many substances dissolved in the water. Fluctuations in the pH level are definitely to be avoided.

JBL Online Laboratory
Regular control for a healthy aquarium/pond with conditions close to nature. Enter your water values into the JBL Online Laboratory and get an in-depth analysis of your values within seconds.

Recommended pH values:
Freshwater aquarium (community aquarium): 6.5-7.5
Lake Malawi/Lake Tanganyika aquarium: 7.8-9.2
Plant aquarium with few fish (aquascaping): 6.0-7.0
Marine aquarium: 7.9-8.5
Pond: 7.5-8.5

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 website. 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.

You will find the colour chart bundle as spare part on the respective product page and in the spare parts shop.

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

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 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.

What is the shelf life of the JBL pH Test 7.4-9.0 ?

The JBL pH test 7.4-9.0 has a shelf life of 3 years in the original sealed bottle.

The following is printed on the bottom of the packaging:

CH/B: 2247 (e.g.) = batch number
BBD: 05/13 (e.g.) = best-before date (month/year)

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

How often do you need to test your pond or aquarium water?

The Water Change In Ponds Is Important!

Water changes have several additional benefits: potentially dangerous substances, such as nitrates and phosphates, are removed from my pond, minerals are added, and any colour cast in the water is reduced.

Testing Water in the Jungle

Our 15 expeditions have taught us something new: In natural waters nitrogens (ammonium/ammonia, nitrite and nitrate) and phosphates are ALWAYS scarce and below the limit of detection. Only when humans have an influence on the natural water, can nitrogens and phosphates be found.
