Product information

Healthy pond with conditions close to nature
The right water values are dependent on the fish stock and the plants in the pond. Even if the water looks clear it can be contaminated. With bad values diseases or algae can appear in the pond. To maintain a healthy 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, phosphate values etc.

Why is testing needed?
The well-being of pond dwellers and the growth of aquatic plants depend to a large extent on the pH level being kept as constant as possible. Many substances dissolved in water are also liable to changes caused by the pH level. Fluctuations in the pH level, in particular, ought to be avoided.

Carbonate hardness (KH) indicates the sum of carbonates (HCO3) and hydrogen carbonates (HCO3)2. These minerals can bind acids and bases and thus stabilise the pH value in the desired range. With KH values below 4 °dKH, the pH value is not stable and fluctuates greatly between 6 and 12. These strong fluctuations affect all organisms in the pond!

JBL Themeworld Pond
Regular monitoring for a healthy pond with conditions close to nature. Here you can find out what the individual water values mean and how you can optimise them if necessary.

Recommended values:
pH value in ponds: 7.5-8.5
Carbonate hardness (KH): at least 4 °dKH

Refill reagents:
For these tests following refill reagents are available: PROAQUATEST pH 3.0-10.0 Refill (2410200) and PROAQUATEST KH Carbonate hardness Refill (2411100)

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.

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

Water stability - A very quick check that your pond water is okay

Every week pond owners need to check how high the pH-value is and whether there is still enough carbonate hardness (KH) to keep the pH-value stable. Both values are basic requirements of a functioning pond.
