Brightwell Aquatics Potassion Liquid Potassium Additive - 500ml

Brightwell Aquatics Potassion Liquid Potassium Additive - 500ml is a highly concentrated ionic potassium solution for marine and reef aquariums, especially systems housing SPS corals or running ultra-low-nutrient filtration methods.

Brightwell Potassion Potassium Additive for SPS Reef Aquariums

Potassium is a major element in natural seawater and is involved in coral growth, coloration, and normal biological function. Potassion helps maintain potassium near natural seawater concentration in reef aquariums where livestock uptake, salt mix variation, zeolite-based filtration, or aggressive nutrient control may contribute to depletion.

Potassion 500ml Reef Potassium Support Features

• Highly concentrated ionic potassium solution for marine reef aquariums.
• Provides potassium used in aragonite formation by corals and other reef-building organisms.
• May support blue coloration in some small-polyp stony corals when other reef conditions are appropriate.
• Useful for potassium depletion associated with zeolite-based ultra-low-nutrient aquarium methods.
• Free of phosphate, silicate, and organic material.
• 80,000 ppm potassium concentration according to current J&L product-page information.

Brightwell Potassion Testing and Potassium Range Notes

• Size: 500 ml bottle.
• Use: Marine and reef aquariums.
• Product type: Ionic potassium supplement.
• Natural seawater potassium concentration is approximately 399 ppm.
• Recommended maintenance range: 390 to 410 ppm potassium.
• Each 1 ml increases potassium in 1 US gallon by approximately 21 ppm.
• For best control, use an accurate potassium test kit before making adjustments.

Potassion Liquid Dosing Directions

Shake well before use. Add 5 ml per 50 US gallons every other day, or as needed to maintain potassium between 390 and 410 ppm. For advanced adjustments, test potassium first and calculate dosage based on total system volume. If potassium is below 390 ppm, do not exceed 10 ml per 20 US gallons daily until the concentration reaches the recommended range. Try to maintain potassium within approximately +/-10 ppm and avoid large uncontrolled changes.
