Product information

Healthy pond environment
The right water values in the garden pond are dependent on the fish stock and plants present there. Even if the water looks clear it can be contaminated. With poor values diseases or algae can appear in the pond. To maintain a healthy pond environment it is important to check and adapt the water values regularly. With the JBL Testlab Koi you can determine the most important water values in your koi or garden pond.

Precisely measures the following values
PO4 sensitive: phosphate content of the water from 0.5 up to 1.8 mg/l
PO4 for koi: phosphate content of the water from 0.25 to 10 mg/l
O2 test: oxygen content
pH test: acidity of the water from 3.0 to10
pH test: acidity of the water from 7.4 to 9.0
KH test: pH stability of the water (carbonate hardness)
GH test: general hardness
NO2 test: toxic nitrogen compound (nitrite)
NO3 test: reason for algae growth (nitrate)
NH4 + NH3: indication of non-toxic ammonium.
Determination of the toxic ammonia using table, ammonium (NH4) is non-toxic for fish, but is partially converted into toxic ammonia (NH3) at pH values over 7.

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.

Why are there no colour charts for the JBL GH test, the JBL KH test, the JBL calcium test Ca and the JBL magnesium test Mg?

The following tests from the test range are so-called titration tests: JBL GH test, JBL KH test, JBL calcium test Ca and JBL magnesium test Mg, where the number of drops are counted until the colour changes and the counted value is multiplied by a value:

GH = number of drops = general hardness in °dH

KH = number of drops = carbonate hardness in °dH

Magnesium + calcium = number of drops * 120 = amount Ca + Mg in mg/l

Calcium = number of drops * 20 = amount Ca in mg/l

Magnesium = amount Ca+Mg from magnesium test - amount Ca in mg/l = magnesium in mg/l

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

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

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.

Algae Control 1-2-3 algae free

A few algae in the pond do not pose a problem and even form a component of a healthy pond. But once the water turns green or „blanket weed“ algae become rampant, you then have a problem which needs fixing. Effective and longterm algae control consists of three steps.
