Potassium is one of the three most important macronutrients for aquarium plants. It not only stimulates growth or new leaf formation but also regulates the water balance and enzymatic reactions of the plant. With balanced potassium values, there is no leaf damage due to nutrient deficiency - vitality is retained. This MasterLine product is a pure potassium fertiliser without trace elements, it can be used immediately, without a lot of calculations.

MasterLine Potassium can be combined with all individual component fertilizers from MasterLine or used in addition to the complete fertilisers, for example, MasterLine All In One. Certain nutrient values can be set in a targeted manner. The dosage is based on the need, it can be reduced or increased: If the potassium concentration falls below 15 mg/litre, fertilization is recommended - this is only a guideline, however.

Recommended dosage: 1ml to 30L = 1mg/L K

Tip: This product is also suitable for shock fertilisation, for example after changing the water.

Note: Shake the bottle well before use; please always keep cool and protected from sunlight.
