Quick test to determine the copper content in fresh and marine water aquariums and ponds

  • Simple and reliable monitoring of the water values in aquariums/ponds. Determines the ideal copper value and monitors heavy metals in fresh and marine water
  • Laboratory comparator system to compensate the inherent water colour: fill plastic cuvette with sample water, add reagents to one cuvette, place cuvettes in holder, read values off colour chart
  • Use: when setting up a new aquarium, in cases of invertebrate and fish deaths and when dosing copper-bearing medications
  • You will find detailed information and troubleshooting tips about water analysis on the JBL website in Essentials/Aquarium or Pond
  • Package contents: 1 copper (Cu) quick test for approx. 50 measurements, incl. 2 reagents, 2 glass vials with screw caps, syringe, comparator block and colour scale. Reagent refill separately available

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?
Copper is a heavy metal which, on the one hand, is essential as a trace element for plant and animal organisms. On the other hand, excessive concentrations can have a devastating effect as a cytotoxin. Copper usually enters the aquarium by means of heavy metals in tap water or by metal objects in the water. And it enters ponds via guttering made of copper alloys. Good water conditioners can bind the copper. But copper can also be useful to combat fish disease.

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 copper content:
In general copper should NOT be measurable in aquariums and ponds.
Any copper content measured in freshwater and marine water could be deadly!
Only copper containing medications should contain a therapeutic dose of 0.3 mg/l and this needs to be set and then checked with the Cu test.

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

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.

After the application of JBL Oodinol 1000 the copper test Cu doesn’t detect any copper in the aquarium. Why is this?

To answer this question some further information is required in order to detect any errors that may have occurred.

1) Are the reagents of the copper test still all right? (best-before date has not expired and it has not be opened longer than about 6 – 9 months.)

2) Has the medication expired? (The best-before date can be found on the bottom of the folding box or the bottle.)

If the answer to the first question is yes and the answer to the second question is no, then please do the following:

1) Fill a 10 l bucket with tap water.
2) Carry out a copper test. The value should be 0 mg/l.
3) Dose JBL Oodinol 1000, following the instructions.
4) Stir the water thoroughly.
5) Carry out a copper test again. The value should be 0.3 mg/l.
6) If the test changes its colour it means both products are all right and the copper will then precipitate in the aquarium.

Copper as a metal is exposed to various processes. These include, for instance:

The precipitation of barely soluble copper salts. The copper mostly accumulates in the filter media. A good remedy for this is to replace the filter media and then repeat the dosage.

Accumulation in the sediments. A good remedy for this is to carry out a substantial water change and suction off the sediment (use a gravel cleaner). Afterwards repeat the treatment according to the instructions.

Consumption by organisms, especially aquatic plants (copper is an essential trace element for aquatic plants), is not usually an issue with the usual medical dosage.
