JBL PROAQUATEST Cu Copper
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: daily in newly set up aquariums, later 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.


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.

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.
