Most tap water supplies are almost void of potassium and this can result in sick or stunted water plants and poor fertility in your fish. Potassium is essential for healthy plants. It assists with photosynthesis and propagation and helps plants resist disease. Potassium in higher levels promotes fertility in fish, increasing spawning frequency and clutch sizes and increasing the productivity and profitability of your fish hatchery. Phosphate free.

Directions: To improve plant growth, add 1 teaspoon or 5g to 130 litres of water. To improve fish fertility, add 1 teaspoon or 5g to 38 litres of water. This will raise potassium levels by approximately 40ppm.
