Maintaining potassium within a range of 400ppm helps in improving the blue/purple coloration and growth of small-polyp stony corals.
DOSAGE – PER 10GAL
Add 1mL per gallon each day until potassium levels reach 400ppm.
MAX DOSAGE: Do not increase potassium levels more than 25ppm per day. 1mL per gal will raise K by 35ppm. Testing potassium levels is HIGHLY RECOMMENDED.
