Product information

Healthy pond environment
The right water values in the garden pond depend on the fish stock, the filtering and the plants. 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 it is important to check and adapt the water values regularly. With the JBL ProAquaTest kit for koi you can determine the most important water values in your koi or garden pond.

Why is testing needed?
In ponds, phosphate primarily enters the water as a result of organic substances (leaves, dying algae), the digestive processes of the fish and food remains. If conditions are unfavourable, the phosphate levels may reach values that are sometimes 100 and more times higher than natural levels. Undesirable algae will then inevitably multiply explosively as a consequence.

BL offers a further phosphate test which can indicate even low phosphate levels in the water. The JBL Phosphate Test sensitive can indicate phosphate levels as low as 0.02 mg/l and as high as 1.8 mg/l in 9 gradations. The JBL Phosphate Test PO4 Koi starts at 0.1 and reaches 10 mg/l in 9 steps.
If the JBL Phosphate Test sensitive indicates the highest value with a dark blue colour (1.8 mg/l) it is not clear whether it is 1.8 mg/l or more and if more, how much more. Then it’s best to apply the JBL Phosphate Test Koi, which can show values as high as 10.0 mg/l.

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

Have you lost your record sheets, used them all up, or need them in another language?
In the appendix of this FAQ you will find PDF files for printing them out in German, English and French.

What happens if I use the wrong side of the spoon for the powder?

Your test result will remain clear or appear slightly yellow, although phosphate may be present. If your test kit has not expired or has been open for more than 9-12 months, this is a clear indication that you have used the wrong side of the spoon.
The small side of the spoon should only be levelly filled and is in the place normally used to hold it. For clarification, take a look at the picture below.

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

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 ml sample + 12 ml dist. water: result X 5
1.5 ml sample + 13.5 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

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.
