Potassium is one of the most important nutrients for aquarium plants. It is the member of the NPK group (Nitrogen, Potassium, Phosphorus) which are the most important nutrients for aquatic plants. Plants need them in a huge amount regularly. So, often a shortage of potassium occurs in the aquarium. That’s when additional potassium has to be supplemented. Aquatic plants absorb potassium in the form of potassium cation K+ .
Potassium deficiency can be one of the most depressing problems in a planted tank. Water doesn’t usually contain it that much, so additional supplement is often required. Usually water doesn’t contain potassium more than 2 parts per million (ppm). Hobbyist often uses Potassium Sulfate aka K2SO4 to their aquarium to supplement potassium. The ideal potassium level in a planted tank should be between 10 to 50 ppm. Weekly 20 ppm of potassium for high light tank and 10 ppm of potassium for low light tank should be added.
Symptoms of Potassium deficiency:
=>small necroses are visible on the older leaves of the plant. They start as a small black spot on the leaves. But eventually they get bigger and often have a yellowish border around them.
=>New leaves become smaller in size and surface.
=>the older leaves may become yellow even before they die. The veins can turn to yellow too.
=>The edges of the leaves turn yellowish.
=> Brown dots can be visible on the leaves.
