sera guide - Splendid plants in your aquarium

Aquatic plants require mineral nutrients in different amounts. They are therefore di- vided into macro nutrients (high require- 6 Macro nutrients include: Nitrogen (N) Phosphorus (P) Sulfur (S) Potassium (K) Calcium (Ca) Magnesium (Mg) Nitrogen is taken up by the plants as nitrate (NO3) or ammonium (NH4 + ). Among others, it is required for the building up amino acids, the basic units of proteins. Phosphorus is taken up as phosphate (PO4 3- ). It is important for obtaining energy in the cells. Nitrogen and phosphorus containing com- pounds are already sufficiently available in the water due to uneaten food and organic waste. However, they first must be converted by micro organisms (e.g. sera bio nitrivec) into a form that can be utilized by plants. Ad- ditional fertilization with phosphate and ni- trate is not necessary in aquariums stocked with animals. This would lead to the opposite and support the growth of unwanted algae. However, phosphate and nitrate must be added in mere plant aquariums (also called “Dutch style aquariums”). sera flore NPKdrops are ideally suited for this purpose. They are exactly blended for densely planted aquariums with low or no fish stock. The ratio between the single elements is perfectly bal- anced to the requirements of aquatic plants. Magnesium is the central component of chlorophyll (green leaf colorant), and it is es- sential for photo synthesis. The other macro nutrients are also required for the growth of aquatic plants.
