Aquarium plants need around 20 different nutrients to grow healthily. Potassium is particularly important. Potassium is a macronutrient and is required by plants in large quantities. Along with the macronutrients nitrate and phosphate, as well as light and CO 2, it is the most important prerequisite for balanced, healthy plant growth.


What is potassium needed for in the aquarium?

Potassium has a variety of functions in plants. It is present in high concentrations both in the cells themselves and in the vascular system. Potassium is an osmotically active ion that is crucial for building up root pressure and cell pressure (turgor). It is also involved in various metabolic processes, e.g. the synthesis of sugars, starch, cellulose and lignin. Potassium can be stored in plant cells and transported within the plant when needed, e.g. from older to younger leaves. A certain amount of potassium is supplied by tap water. The harder the water, the more; the softer the water, the less. You can ask your local water supplier about the content. Potassium is only introduced into the aquarium in very small quantities via food and fish excrement. Good aquarium fertilizers (micronutrient fertilizers/complete iron fertilizers) such as Dennerle Plant Care Pro therefore always contain an appropriate amount of potassium. This is usually sufficient for normal, planted community aquariums. However, the situation is different for demanding plant aquariums (e.g. aquascaping aquariums, Holland aquariums). They have an above-average need for nutrients, especially macronutrients. Such plant aquariums are characterized by

  • dense planting (more than 70 – 80 % of the soil surface)
  • many fast-growing species
  • lots of light (30 – 60 lumens/liter or more)
  • CO 2 fertilization
  • 30 – 50 % partial water change per week
  • no or little fish stock (but with shrimp)

Detecting potassium deficiency in the aquarium

These types of aquariums can suffer from a potassium deficiency, particularly in soft water. It is primarily evident on the older leaves. When required, the element is transported from the older leaves to the younger leaves via the vascular system. Typical symptoms are yellowing (chlorosis), which can appear in dots or areas between the leaf veins or on the leaf edge. Later, the tissue dies in dots or areas (necrosis). Some plants are particularly sensitive to low potassium levels. Well-known examples are the parrot leaf ( Alternanthera ) and the cognac plant ( Ammania ). Growth can suddenly stop and the newly formed leaves are stunted. In the Indian water fern ( Hygrophila polysperma ), potassium deficiency is evident on the older leaves in the form of small black dots (necrosis).

Correcting Potassium Deficiency in the Aquarium

For this reason, with demanding plant aquariums it is a good idea to keep an eye on the potassium content and top it up if necessary. Each aquarium has a specific nutrient requirement depending on the number of plants, type of plant, animal population, feeding, water changes and growing conditions (amount of light/lighting time, CO2 addition, filter technology, etc.). The amount of fertilizer required should therefore be determined individually for each aquarium. If the aquarium needs all three macronutrients N, P and K, the use of Dennerle Plant Care NPK is recommended. The nutrient ratios have been chosen so that all macronutrients are absorbed by the plants in equal proportions. Even with long-term, regular use, deficiencies or disadvantageous accumulations of individual nutrients cannot occur. Biological balance is particularly important with macronutrients, i.e. the nutrients should always be present in a certain ratio to one another. Nutrient imbalances should be avoided as they usually lead to algae problems. If the potassium content in the tap water is too low - which is often the case with soft water - or the aquarium has an increased need for potassium, Dennerle Plant Care K should be used to specifically supply the plants with potassium. If you have measured and fertilized regularly for several weeks, you can see at what level the measured values ​​​​settle and what amount of potassium the aquarium needs. You can then add the determined weekly dose of Plant Care K as standard and increase the measurement intervals to 2 to 4 weeks with a clear conscience. A macronutrient fertilizer must always be used in combination with a micronutrient fertilizer (complete iron fertilizer). For a complete supply of nutrients and the best possible plant growth, we recommend combining it with Dennerle Plant Care Pro . For magnificent plant growth and healthy fish and shrimp, we recommend a partial water change of 25% to 50% per week. This removes waste and inhibitors and avoids nutrient imbalances.


dosage

The fertilizer can be dosed precisely and accurately: 2 ml per 100 L adds 1 mg/L of potassium. The optimal potassium concentration is in the range of 10 - 20 mg/L. We recommend measuring the potassium content regularly and dosing Plant Care K accordingly. Plant Care K can be used as a weekly fertilizer or daily fertilizer.

Inspiring and well-written
This is a very interesting book written by some Harvard profs. They did a large national survey of innovative businesses and their leaders. The book posits that innovative people follow five skills: associating, questioning, observing, networking, and experimenting. These skills can be found at the individual or organizational level. The idea is that most people have these skills in their DNA and can bring them out with some practice. There are a lot of interesting and inspiring examples like Steve Jobs and Jeff Bezos. Although this book seems like a self-help type book with a lot of hype, it has an academic underpinning. Any organization that is interested in promoting innovation could benefit from encouraging these 5 skills. If you are interested in innovation or creativity in business or any organization that produces something, you will like this book. The books is a little distracting to read because it has sidebars all through it giving interesting examples that break up reading concentration. Aside from that, it is a well-written book that is easy and enjoyable to read. I enjoyed the book greatly and found it to be inspiring.

Great read and research. But what about daily application for regular people?
The research piece behind this book might be the next thing I read, as I'm intrigued by the academic rigor applied. The reveal and living examples of the five skills - questioning, networking, experimenting, observing and associating - are tangible and approachable given their articulation through well-known and highly visible entrepreneurs running innovative companies. There's much to be gleaned by looking at the way these people behave and, even through simple emulation, enhancing one's own skills. My only real disappointment with the book is its limited approach to practical, daily application for those not yet at the top of the tree. It's rather a different kettle of fish for the innovation-minded, but stuck in bureaucracy, worker who wants to make things better, is still motivated, and hasn't been crushed by the machine. How does that person actively innovate? And, in some cases, get away with it? This book (or an accompanying volume) focussing on daily, in-work, innovation would be useful.

An exceptional five stars out of five
Few qualities separate inordinately successful entrepreneurs from the rest of the pack than the ability to innovate. Many have debated whether individuals are born with this quality or whether it can be nurtured. In The Innovator's DNA, Jeff Dyer, Hal Gregersen and Clayton Christensen explain that while genetics play a role, innovation is most certainly a skill that can be learned. In particular, the authors introduce and expound upon five "discovery skills" found in the leaders of some of the most innovative companies in the world: (1) associating, (2) questioning, (3) observing, (4) networking and (5) experimenting. Each discovery skill is accompanied by real-world examples and pragmatic exercises that make the book unusually valuable in an age where copious books on change, leadership and innovation overwhelm the already-overwhelmed executive. I give The Innovator's DNA an exceptional five stars out of five. The authors present a very readable book and provide concrete exercises for developing innovative skills. Using the principles provided in the book, I created a folder on my computer that I call my "Innovation Room." I use this to track progress as I work through various exercises and as I take time to ponder about how to apply innovative solutions to extant problems in Utah. This book was and will continue to be useful to me, and is recommended as a must-read for those interested in adding rare innovative attributes to their arsenal of problem-solving and decision-making skills. *NOTE: The preceding text is taken verbatim from my short book review printed in the June 2012 edition of Utah Business.

It's Ok
It's an ok book and it definitely has some interesting things going on it, but it also has those "ask yourself" these questions if you can be an innovator which is where every human being ponders and talks themselves into having the type of characterisitic the question asks if they have and that makes that human being feel the best about themselves. Bottom line the book has some good info, is it better than say reading the biography of each innovator that they cover (if one is available)....I can't say that it is.
