Simplify potassium supplementation in reef aquariums. Concentrated solution replenishes depleted levels of potassium, an important component of aragonite. Potassium is incorporated into the skeletal material of corals and other reef-building marine organisms for growth. Regular dosing of potassium has also been implicated in improving the blue coloration of numerous varieties of small-polyp stony corals. Use Potassion in marine aquariums housing small polyp stony (sps) corals. 500 ml treats up to 5,000 gallons.

Instructions and Guidelines|
Note that the natural seawater concentration of potassium is approximately 399 ppm. Maintaining the potassium concentration in marine aquaria as closely to this value as possible is recommended.
Basic: Shake product well before using. Add 5 ml (1 capful) of product per 50 gallons of aquarium water every other day or as needed to maintain the potassium concentration within a range of 390 to 410 ppm. When used in this fashion, 250 ml treats up to 2,500 gallons.
Advanced: Determine the potassium concentration in the aquarium using an accurate test kit before supplementing. Shake this product well before each use. Each ml of Potassion will increase the concentration of potassium ("[K+]") in 1 gallon of water by approximately 21 ppm. If the initial [K+] in the aquarium is below 390 ppm, add this product at the maximum rate of 10 ml per 20 gallons daily until potassium concentration measures between 390 and 410 ppm. Then dose daily or weekly as needed. Always try to maintain the [K+] within a range of ± 10 ppm. To determine the dosing rate of this product once the desired [K+] has been acquired, measure the daily rate of potassium uptake (i.e. the decrease in potassium) in your aquarium by measuring the [K+] at the same time each day over a one to two week period. To determine the daily dosing rate (preferable to weekly dosing) for potassium maintenance: Estimate the volume of water in the entire aquarium system; divide the daily decrease in [K+] by 21; multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable [K+] (and more natural environment) than dosing weekly, in which the [K+] spikes just after dosing and then gradually decreases throughout the course of the week.
Maintaining potassium within a range of 390 to 410 ppm is sufficient for long-term health, growth, and coloration of corals when all other physical and chemical requirements are met. The rate at which potassium is extracted from the water is determined by the stocking density of potassium-depleting livestock, characteristics of lighting and method(s) of filtration employed, and other biological, physical, and chemical conditions. Therefore, each aquarium will have different requirements for the rate of potassium supplementation. Once the rate of potassium uptake is determined, the proper dosing rate of this product can be easily calculated. It is recommended that a quality salt mix with the proper (not augmented) alkalinity and concentrations of major, minor, and trace elements be used to establish natural seawater parameters in marine aquaria. Therefore, providing a stable ionic foundation on which to build.
