SALIFERT Potassium (K) Test (Freshwater)
Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content.
Potassium is introduced to your system in the form of fish feed or supplements like potassium hydroxide. However, the potassium levels in most fish feeds aren’t adequate for both plants and fish.
Potassium is the most commonly deficient nutrient by far and it also has a complicated relationship with other nutrients in the system, which makes it tricky to manage.
Potassium deficiencies will show up initially as interveinal chlorosis (when the space between the plant veins yellow starting in the older leaves. This is because potassium is mobile in the plant, allowing the plant to reallocate what potassium it has from the old growth to the new, delicate growth.
If the potassium deficiency isn’t initially treated, it will get worse, culminating in browning, drying, and death of the edges of the leaves. In addition, you will find dead spots on the leaves.
