Flourish Potassium™ contains 50,000 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.
The most easily obtained sources of potassium are potassium nitrate and potassium phosphate. Both of these sources add to either nitrogen or phosphorus as well as potassium, making it virtually impossible to target a specific NPK ratio. Flourish Potassium™ is derived from potassium sulfate, allowing the user to adjust potassium levels without affecting nitrogen or phosphorus.
Sizes: 50 mL, 100 mL, 250 mL, 500 mL, 2 L, 4 L
A: About 50 mL.
A: Yes, Flourish Potassium™ is safe for freshwater shrimp including Amano shrimp (Caridina japonica)
A: Potassium is a major nutrient and I've seen a wide range of recommended values all with good success between 30 - 120 ppm. Our Equilibrium™, if used at the recommended dose, will raise potassium to 50 ppm. The recommended dose of Flourish Potassium™ will increase potassium levels by 2 mg/L. As of now we do not manufacture a potassium test kit but there are some on the market that are available. The rate that you are dosing Flourish Potassium™ is definitely acceptable as this dosing regimen, along with using Equilibrium at water exchanges, should maintain potassium levels around 50 ppm depending on rate of consumption by your plants.

Elemental potassium is present at a concentration of 50,000 ppm (e.g 5%). Fertilizer laws require us to list potassium in terms of equivalence to a material that is not present (K2O) rather than the more scientifically sound method of simple elemental equivalence.
