Don’t let your plants starve!
A lot of aquarium owners have house plants, which they (to some extent) fertilise on a regular basis. Yet they don’t consider a fertilisation for their aquarium plants necessary. In their opinion the aquatic plants receive all the growth requiring substances they need through fish excrement and the water.
But this is only very slightly the case. Yes, the plants are supplied with water and, due to fish excrement, also with nitrogens and phosphates. But no, unfortunately this is not enough!
The main nutrient for plants is carbon dioxide (CO2), which they transform during photosynthesis with the help of light energy and water into food (sugar), releasing oxygen as a by-product.
As a consequence the use of a CO2 fertiliser system is the most important way to supply your plants with food. Certainly there is CO2 dissolved in your aquarium water, but for most plants this is not enough for a vigorous growth.
Which water tests are important? How can you achieve perfect water values?

How important is CO2 plant fertilisation? Why do your plants need additional CO2? How does a CO2 system work?
Comparing this main food CO2 with the food humans need would mean it corresponds to our proteins, fats and carbohydrates. But for us humans these main nutrients alone are not sufficient. Without additional vitamins, minerals and trace elements we could become seriously ill and have a shorter life. In the same way plants require minerals and trace elements as well as CO2, and we can supply these with substrate and liquid fertilisers.
