In the field "How do you fertilize?" select "Prepare mortar" or "Powders straight into the aquarium."
Choose the amount of each substance and in what form you add,
enter all the components of your fertilizer.
The calculator in the lower field will show how much mg / l (ppm) will be added to the aquarium per week. Compare with recommended values.
