Using the Korallen-Zucht Potassium Test Kit, the current tank water potassium levels can be determined by looking through a test solution onto a color coded scale. Potassium levels around 380 mg do not change much if salt with sufficient potassium is used for water changes. A test every two weeks is enough in that case.
Potassium levels can be raised slowly with K-Balance or K-Balance strong until the test shows a 380 mg. Each of the dosing amounts of these products depends primarily on the amount of inhabitants in your tank. The recommended amounts and intervals are based on average well-stocked tanks. One hundred percent of all of these elements will be taken up and used by the corals. The more animals in the tank, the more amounts you should dose to make all elements available at all times. We strongly recommend adjusting the dosing regimen based on your corals.
