Dennerle Plant Care NPK is a macro-nutrient fertiliser for aquariums without or with low fish stocking.
The three macro-nutrients N = nitrogen (nitrate), P = phosphorus (phosphate) and K = potassium are of particular importance. The addition of N and P is usually not necessary in normal, planted community aquariums, as these substances enter the aquarium in sufficient or sometimes even too large quantities via food and fish excretions.
For demanding plant aquariums or aquascaping aquariums, on the other hand, the situation is different. They have an above-average nutrient requirement, especially for macro-nutrients. In these types of aquariums, an N or P deficiency can quickly occur, especially without or with low fish stocking. A K deficiency is also possible, but rarer, as potassium is always present in the tap water in some quantity and is regularly introduced via complete iron fertilisers such as Plant Care Pro. For demanding plant aquariums, it is therefore very sensible to keep an eye on the macro-nutrients and supplement them if necessary.
The biological balance of the nutrients is particularly important in an NPK fertiliser. The nutrient ratios in Plant Care NPK have been chosen so that all three macro-nutrients are taken up by the plants in equal proportions. This means that even with long-term, regular use, there can be no deficiencies or detrimental accumulation of individual nutrients. This is because nutrient imbalances must always be avoided, as they usually lead to algae problems.


  • Macronutrient fertiliser for heavily planted aquariums with a low fish stocking rate
  • With nitrate (NO3), phosphate (PO4) and potassium (K) plus magnesium (Mg)
  • For magnificent plants and intensely bright colours
  • Immediate and long-term effect


Add Dennerle Plant Care NPK to the aquarium after a water change in a place with good water movement. Screw the cap back on after use (do not rinse with aquarium water). We recommend checking the nitrate and/or phosphate content of the aquarium water regularly.
