Healthy aquariums with conditions close to nature
The right water values are dependent on the fish stock and the plants in the aquarium. Even if the water looks clear it can be contaminated. With bad values diseases or algae can appear in the aquarium. To maintain a healthy aquarium 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?
Silicon is one of the most common elements in the world. As a result of the weathering of silicate rocks, silicon is washed into surface and ground water in the form of silicate. Depending on the composition of the rocks in a particular area, the mains water will contain varying amounts of dissolved silicate. The significance of silicon for aquariums and garden ponds is as a nutrient for diatoms, some aquatic plants, siliceous sponges and many other invertebrates.

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 silicate values:
Freshwater aquarium (community aquarium): 0-2.0 mg/l
Lake Malawi/Lake Tanganyika aquarium: the silicate content is not relevant here because grazing fish species like eating diatoms.
Plant aquarium with few fish (aquascaping): 0-2.0 mg/l
Marine water Aquarium: 0-1.0 mg/l
Pond: 0-2.0 mg/l

Frequently Asked Questions (FAQ)

_x000D_

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

_x000D_

_x000D_

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?

_x000D_

_x000D_

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


JBL CO2 direct test kit, JBL Ca Calcium test kit and JBL Mg+Ca Magnesium+Calcium test kit:

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.

_x000D_

_x000D_

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 ?

_x000D_

_x000D_

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.
