JBL ProScape NPK Macroelements

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 nitrates and phosphates 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. JBL ProScape NPK Macroelements supplies the tank water with nitrogen and phosphorus in the form of nitrate salts and water-soluble phosphate salts. As a result, the aquatic plants obtain the supply of nitrogen they require. Potassium and magnesium are also added to the water at the same time.

1 ml JBL ProScape NPK Macroelements contains
50 mg nitrate nitrogen
2 mg phosphate
30 mg potassium
1 mg magnesium

Dosage JBL ProScape NPK Macroelements
The normal dosage is 5 ml per 100 litres of aquarium water for very well-lit tanks. For not so well-lit tanks the dosage is 2.5 ml per 100 litres of aquarium water.

Healthy plant growth is based on the following three main pillars: A supply of light, a supply of CO2 and an adequate and 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 following levels should be maintained for well-lit planted aquariums:
CO2: 20-35 mg/l
Nitrate nitrogen (NO3): 10-30 mg/l
Potassium (K): 10-30 mg/l
Phosphate (PO4): 0.1-1.5 mg/l
Iron (Fe): 0.1-0.5 mg/l
Magnesium (Mg): 5-10 mg/l
