Each pack consists of around 50 strips. Potassium is a macronutrient and at least as important as iron for a good and healthy plant growth. Therefore it is important to check the level of potassium to prevent levels becoming too low and keep them in a healthy range ( 10-15 mg/l). The Easy-Life Potassium test is a colour test with a colour chart. Optimum level for a planted aquariumAquarium plants benefit from 10 -15 mg/l (=ppm) of potassium. A level below 5 mg/l (=ppm) is not desirable and can lead to growth problems, yellowing of the leafs and deformations. Often lack of potassium is confused with lack of iron, also because potassium was very difficult to measure until now. If the level is too low, extra potassium will help the plants to recover faster and they colour to become more vibrant. Please note it may take up to a working week before we ship this item.
