The three macronutrients N = nitrogen (nitrate), P = phosphorus (phosphate) and K = potassium are particularly important. The addition of N and P is generally not necessary in normal, planted community aquariums, as these substances enter the aquarium in sufficient or sometimes even excessive amounts via the food and fish excrement. The situation is different with demanding plant aquariums or aquascaping aquariums, however. They have an above-average nutrient requirement, especially for macronutrients. In these types of aquariums, an N or P deficiency can quickly occur, especially with no or few fish. A K deficiency is also possible, but less common, as potassium is always present in certain quantities in tap water and is regularly added via iron fertilizers such as Plant Care Pro . In demanding plant aquariums, it is therefore very useful to keep an eye on the macronutrients and supplement them if necessary. The biological balance of nutrients is particularly important for an NPK fertilizer. The nutrient ratios in Plant Care NPK were chosen so that all three macronutrients are absorbed by the plants in equal proportions. This means that even with long-term, regular use, there can be no deficiencies or disadvantageous accumulations of individual nutrients. Nutrient imbalances should always be avoided, as they usually lead to algae problems.

When do I use Plant Care NPK ?

Every aquarium has a specific nutrient consumption depending on the number of plants, plant species, animal population, feeding, water changes and growth conditions (amount of light/lighting time, CO2 addition, filter technology, etc.). The required NPK addition should therefore be determined individually for each aquarium. Plant Care NPK is only used when necessary, i.e. when there is a real lack of macronutrients. We recommend measuring the nitrate and/or phosphate content weekly and dosing Plant Care NPK accordingly. You can also measure the potassium content of the aquarium water (tests available from specialist retailers). However, this measurement is usually not necessary, as the tap water plus Plant Care Pro and Plant Care NPK provide enough potassium. An overdose of potassium is hardly possible in practice and is generally not detrimental. Significant overdoses of nitrate and phosphate, on the other hand, can promote algae growth. Plant Care NPK should therefore not be used at the beginning without first measuring the nitrate and, ideally, the phosphate content. If the tap water used for the water change does not contain exceptionally high amounts of nitrate or phosphate, measuring the nitrate content alone is sufficient later on in practice as a basis for deciding on NPK fertilization and dosage. Simple immersion tests can also be used for this, e.g. the Dennerle WaterTest 6in1 .

Dosage & Application

If you have measured and fertilized regularly for several weeks, you can see at which level the measured values ​​​​settle and which macronutrient additions the aquarium requires. You can then add the determined weekly dose of Plant Care NPK as standard and increase the measurement intervals to 2 to 4 weeks with a clear conscience. A good guideline is 10 ml / 100 L / week , which corresponds to an addition of 5 mg/L nitrate, 0.4 mg/L phosphate and 2.5 mg/L potassium. If the tap water used for the water change contains exceptionally high levels of nitrate (e.g. 50 mg/L) but hardly any phosphate, or high levels of phosphate (> 1 mg/L) but hardly any nitrate, then the use of Plant Care NPK is not recommended in order to avoid disadvantageously high levels of individual macronutrients and nutrient imbalances. In this case, Dennerle Plant Care N or Plant Care P single-nutrient fertilizers should be used to specifically compensate for nutrient deficiencies. Because in addition to the absolute nutrient concentration, the nutrient ratio is also important. The nitrate-phosphate ratio should ideally be in the range of 10:1 to 15:1. If the tap water only contains small amounts of potassium (e.g. < 3 mg/L), Dennerle Plant Care K should be used. This is often the case with very soft water. You can find out the analysis values ​​for your own tap water from your local water supplier. They are easy to access online. Furthermore, potassium is one of the few nutrients that only get into the aquarium in trace amounts through fish food. A macro nutrient fertilizer must always be used in combination with a micro nutrient fertilizer. For a complete supply of nutrients and the best possible plant growth, we recommend combining Plant Care NPK with Plant Care Pro .

Perfect case for my daughter’s iPad
Color: Purple Pink
bought this case for my daughter. The fit is perfect — all the buttons and camera line up exactly and it snaps on securely. The case feels sturdy, protective, and durable but not too heavy, so she can still carry it comfortably. The stand feature is convenient. The design is also super cute — Luna loves it Overall, great quality for the price. I would definitely buy it again

Very versatile!
Color: Colorful Pink
I got this iPad case for myself and my two year-old daughter as we both use this iPad. This case has definitely held up very well. I love the material because it’s nonslip so it’s easy for my two-year-old to hold I also love the movable and adjustable prop on the back that also doubles as a handle. There is two spots to put your Apple Pencil, so that’s very neat. It is a little bit bulky, but it is very protective and I think that is a good trade-off. There is also a cover for the charging port to prevent dust from getting in there or any spills. At first I was a little bit weary about it having a built-in screen protector, but it’s very clear and does not interfere with using the screen at all, so it’s actually a nice touch. I really love this thing and think it is worth it!
