Use the EHEIM aquarium app to analyse the measured water values of your aquarium and get a result specifically customised for you and the matching optimisation notes.
For this, create your profile already at the beginning by storing the water type, shape and size of the aquarium and the resulting volume. If any test results are critical, you will automatically be reminded after one day to repeat the measurement.
You can also create individual reminders which remind you to perform a new measurement of your water values on a certain day or at regular intervals. Each measurement of your water values will be saved to give you access at any time.
