Potassium plays an important role in coral development and colouration. Aquaria running at very low nutrient levels seem to be particularly susceptible to potassium deficiencies - symptoms include slower growth and washed out coral colours, particularly in Montipora species. Additions of potassium can particularly improve red coral pigments. TheReef® Potassium liquid supplement contains pure potassium salts that can be readily taken up by corals and other marine organisms. Guidance: First measure potassium levels in your aquarium with an accurate test kit to determine how much of the supplement you should add. Natural Sea Water values for potassium are around 390-410ppm while 15ml (1 capful) of TheReef® Potassium supplement per 100 litres of aquarium water will raise potassium levels by around 10ppm. Shake bottle before use then add required quantity of supplement to an area of aquarium or sump with high flow. Do not raise levels by more than 10ppm a day. Do not mix with or use within 1 hour of alkalinity, boron or other carbonate type additives and supplements. Store above 10°C.
