1. Register on the website lab.tropic-marin.com and create your aquariums.

2. Register your water sample with the individual sample number (in the packaging) on the website. To do this, go to the website and enter the number code under “new sample”. Alternatively, simply scan the QR code on the label with the sample number. This step is very important: without registering the sample, the water sample sent in cannot be assigned and you will not receive a result.

3.  Rinse the cuvettes several times with aquarium or osmosis water.

4. Take two water samples one after the other using the syringe provided. Squeeze the first 10 ml of water back into the aquarium through the syringe filter and then squeeze the remaining 15 ml into the cuvettes and seal them.

5. Stick a label with the sample number on each cuvette.

6. Stick the address label on the packaging box and send the water samples to the specified address.

7. You will be informed by e-mail when the analysis is complete. You can call up the results as a PDF or display them online. In the latter case, a history of the water values for each aquarium is also displayed.

You can find an illustrated quick guide here.
