Description
Product Details

In a thriving planted aquarium potassium can become the limiting factor to growth if it is depleted. Flourish Potassium™ is an integral Seachem product for plants and is recommended for use with other Flourish® products as well as our gravel, Flourite®. When making water changes, use Equilibrium™ to make the initial concentration of potassium. Flourish Potassium™ contains no phosphates or nitrates.

DIRECTIONS: Use 1 capful (5 mL) for every 125 L. Repeat 2–3 times per week or as needed. For lower doses the thread serves as a guide, each thread representing approximately 1 mL.
