Strontium is found in the bones of fish and, more importantly, in aragonite, the mineral secreted by reef-building marine invertebrates such as corals, clams, tube worms, and their respective allies. Overall, strontium accounts for between 0.75 - 1.00% of aragonite's total mass, and findings suggest that strontium itself induces inorganic precipitation of other ions, creating abiogenic aragonite. Rapid growth rates of corals and other reef-building invertebrates witnessed when strontium is maintained at the natural seawater concentration of approximately 8 ppm suggest this element's importance in the marine environment.
The rate at which strontium is extracted from the water is determined by the stocking density of reef-building livestock, type of lighting, and other biological, physical, and chemical conditions; therefore, each aquarium will have different requirements for the rate of strontium supplementation. Once the rate of strontium uptake in the aquarium has been determined (see below), 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 the reef aquarium, providing a stable ionic foundation on which to build.
The basis of healthy, rapidly-growing reef-building invertebrates is simply providing proper physical and chemical conditions. Maintaining calcium, magnesium, and strontium at natural seawater concentrations and alkalinity between 7 - 12 dKH is the first step towards achieving this goal.
Instructions and Guidelines:
Basic: Shake product well before using. Add 5 ml (1 capful) of product per 20 US-gallons of aquarium water every other day or as needed to maintain the strontium concentration within a range of 8 - 12 ppm. When used in this fashion, 250 ml treats up to 1,000 US-gallons (3,750 L).
Advanced: Determine the strontium concentration in the aquarium using an accurate test kit before supplementing. Shake this product well before using. Each ml of Brightwell Aquatics Strontion will increase the concentration of strontium (Sr2+) in 1 US-gallon (3.785 L) of water by 8 ppm. If the initial Sr2+ in the aquarium is below 8 ppm, add this product at the maximum rate of 10 ml per 20 US-gallons daily until the desired concentration is attained, then dose daily or weekly as needed (see below). If not using a test kit, add 5 ml (1 tsp) of Strontion per 20 US-gallons of aquarium water in two-day intervals to maintain the Sr2+ within the proper range. Always try to maintain the Sr2+ within a range of +/-2 ppm. To determine the dosing rate of this product once the desired Sr2+ has been acquired, measure the daily rate of strontium uptake (i.e. the decrease in strontium) in your aquarium by measuring the aquarium's Sr2+ at the same time each day over a one-to-two-week period. To determine the daily dosing rate (preferable to weekly dosing) for strontium maintenance: estimate the volume of water in the entire aquarium system; divide the daily decrease in Sr2+ by 8; multiply this number by the volume of water in the system to get the daily dosage required (ml) to maintain a stable Sr2+. Daily dosing maintains a more stable Sr2+ (and more natural environment) than dosing weekly, in which the Sr2+ spikes just after dosing and then gradually decreases throughout the course of the week.
