Product information

Healthy aquariums with conditions modelled on nature
The right water values are dependent on the fish stock and plants in the aquarium. Even if the water looks clear it can be contaminated. With bad values diseases or algae can appear in the aquarium. To maintain a healthy aquarium with conditions close to nature it is important to check and adapt the water values regularly.

Water analysis using your smartphone – the new generation

Fast diagnosis, precise results and recommended solutions
Saves measurement values
Displays measurement evaluation
New developments - new functions and uses

Fast diagnosis - precise results
Download the JBL app free of charge, follow the app’s instructions, immerse the test strip into the aquarium water, position the test strip on the JBL colour chart for the analysis, scan colour chart, values will be determined, individual solution recommendations and tips will be transmitted.

Note: The test strips are only suitable for one measurement each. A repeated scan of the strip leads to different values, since the strip goes on reacting indefinitely.

During the analysis "aquarium freshwater"”and "water" the current CO2 content in the water will be calculated as an additional bonus. Depending on the analysis results in the sections “Aquarium Freshwater” and “Garden Pond” individualized recommendations and hints will be transmitted as to which JBL products will help to set the ideal/optimal water values.

Can I print out my ColorCard myself?

Unfortunately it is not possible to print the ColorCard of ProScan yourself. It is produced by means of a special printing process and afterwards tested on a special device for colour fastness.
Only this way can we guarantee the high accuracy of measurements made with the ProScan test kits.

After using the ProScan app my JBL account is locked

Please log out from the ProScan app. Either ask the help desk to unlock your account or change your password. Now you can register again to return to the app.
Why did it happen? Old unsynchronised measurements are being transferred with the old access data. The app offers a data reconciliation in the background. After repeated data reconciliation attempts your access gets blocked for security reasons. Please do not change your data until all the measurements have been transferred from the app.
The easiest way to prevent such problems when changing the access data is to log out from the app.

Does the test also work correctly in osmosis and distilled water?

In weakly buffered solutions such test methods can’t deliver reliable test results for pH values.
Further parameters, such as NO3, NO2, GH, KH und Cl are not affected by this. But the calculations of the CO2 content can here also lead to incorrect values.

Why do I get an error message that the test strip is not correctly aligned?

In the operating system of your smartphone there is a resource management. This also manages your camera. Because other apps are accessing the camera too, it can occasionally happen after use that a new access is not granted and therefore a blockage can occur. As result you receive an error message from your ProScan app despite a correctly aligned analysis strip. Especially after an update you can find the resource “camera” blocked for further apps, including JBL ProScan.

In many cases the solution is quite simple: Close all the apps in the background on your task manager. Now restart your smartphone and open JBL ProScan as your first app. Carry out the scan again. By closing and restarting all the resources will be released. If the error still occurs, the test strip is not correctly aligned on the ColorCard. You can also test the app is working by carrying out a test scan without an analysis strip and using the empty ColorCard.

Elevated levels of chlorine due to damp

A loose seal may result in an indication of positive false chlorine values occurring with the following batches of the ProScan Recharge test strip sets: 421141; 44114; 42114; 43114 and 11035.

If you have purchased your ProScan within the last 6 months, we will send you a refill pack free of charge. Please remember the test strips can be damaged by humidity through a longer service life and frequent use. A package (24 test strips) should therefore be used within 9 months. Converted into use this means that you should carry out a water test every 1.5 weeks.

Why is the KH higher than the GH?

Aquarium problems

Are you faced with algae problems or don’t your aquarium plants grow well? Is the water cloudy or are your fish ill? Don’t your water parameters correspond to your expectations? Our team of experts has thoroughly analysed the problems that occur in the aquatic field and offers you solutions which really work.

Pond care

The different seasons (at least in Central Europe) require different care measures. Even in countries where there are no cold winters with minus degrees, factors like rainy seasons, dry seasons or perhaps a summer with particularly high temperatures all play a decisive role for the garden pond.

Fish diseases

In case your pond fish fall ill, we will show you which disease it is, and how to combat it reliably here.

Algae problems

Why are algae a problem? What algae species can be found in the pond and how can you combat them effectively and for the long-term?


JBL has revolutionized water testing and can turn your smartphone into your personal water test center by means of a free app. All test results will be directly displayed in numerical values and additionally evaluated (good, medium, poor).
