Guaranteed Analysis: Soluble Potassium (K2O) 05.8%
Derived from: Potassium Sulfate
Sizes: 100 ml
Flourish Potassium contains 40,000 mg/l of potassium suitable for the natural planted aquarium. Potassium is one of several elements that are vitally important to maintaining a vigorous level of growth in a planted aquarium. Potassium can become depleted in a rapidly growing system or when the source water has a low mineral content. In these cases potassium could become the limiting factor to growth. Use Flourish Potassium to prevent potassium depletion (signs of which include yellowing in older leaves) and maintain the highest level of growth.
Elemental potassium is present at a concentration of 50,000 ppm (e.g 5%). Archaic fertilizer laws require us to list potassium in terms of equivalence to a material that is not present (K2O) rather than the more scientificaly sound method of simple elemental equivalence.
Use 1 capful (5 ml) for every 125 l (30 gallons*). This dose raises potassium by 2 mg/l. Repeat operation 2 - 3 times per week or as needed (in response to signs of potassium deficiency in older leaves which includes: chlorosis (yellowing), necrosis (death/browning), and weak stems and roots.
