Healthy plant growth is based on the following three main pillars: A supply of light, a supply of CO2 and an adequate/optimal supply of mineral nutrients. The supply of nutrients is described by Liebig’s Law of the Minimum. According to this concept, the nutrient which is available in the minimum amount limits the growth of plants regardless of whether it is a microelement or a macroelement. Microelements are trace elements which plants need in small amounts, whereas macroelements are used for growth in larger amounts.
In a well-planted aquarium, both microelements and macroelements are consumed in large amounts. Particularly when the fish population is small, the microelements, as well as the macroelements of nitrogen, phosphorous and potassium, quickly drop down to the minimum.
The macroelements can easily be supplied by using JBL ProScape NPK Macroelements or by adding each of the individual components, nitrogen, phosphorous, potassium and magnesium, separately. If the latter procedure is selected, it is recommended to check the water values with the JBL Test Set each time.
Nitrogen in the form of oxygen compounds (NOx) or hydrogen compounds (amines – NH2) have essential functions in an organism, such as in protein metabolism.
Whereas it is more common to find an excess of nitrogen in aquariums with larger fish populations which, in turn, can lead to algae growth, nitrates are often in scarce supply in planted aquariums due to consumption by the aquatic plants. This limits growth in the tank.
As the concentrations of nitrate in the drinking waters usually used in aquariums vary considerably, depending on the water supplier, it is advisable to use JBL NO3 Test Set to determine the current nitrate concentration of the water before adding the JBL ProScape N Macroelements fertiliser.
JBL ProScape N Macroelements supplies the tank water with nitrogen in the form of ammonium salts and nitrate salts. As a result, the aquatic plants obtain the supply of nitrogen they require. Potassium and calcium are also added to the water at the same time.
- For the fertilizing of plants in aquariums with few or no fish population, such as nano aquariums and aquascaping aquariums. Standard dosage in aquariums with CO2 fertilization and a lot of light: 2 ml/100 l.
- Contains additional potassium, calcium and magnesium
- Recommended level: 10 – 30 mg/l.
- The dosage can be checked with the JBL nitrate test.
- Contains a 2 ml dispenser.
|Dosage per 100 Liter|
|Well lit tank (1 Watt per Liter) + CO2||2 ml daily|
|Without CO2||2 ml per week|
The normal dosage is 2 ml / 100 l of water for a very well-lit tank with >= 1 W / l of illumination and 1 ml/100 l of water for a tank that is not as well lit. The supply of carbon dioxide must also be considered.
The above table shows recommended fertiliser concentrations according to the general conditions of the aquarium.
As actual precise consumption cannot be predicted, we recommend checking the nitrate concentration with the JBL NO3 Test Set, especially prior to each follow-up dose.
