What is the role of potassium in aquascaping?

Potassium is classified as part of essential macronutrients for plants. Potassium allows the movement of water, nutrients and carbohydrates in the plant’s tissue. At the same time it also regulates the rate of photosynthesis. Yellowing of older leaves may indicate a potassium deficiency but over-dosing potassium will also have the same symptom when potassium causes the depletion of nitrogen. Over dosing potassium will also cause the deficiency of minerals that are part of General Hardness (GH), magnesium and manganese. Generally speaking, a concentration of 15-35mg/l will give the best result.
