Brightwell Aquatics Overview
  • High-purity powdered strontium.
  • Incorporated by corals, clams, and other reef-building invertebrates into aragonite, the mineral that is secreted as skeletal material.
  • Stronger and more economical than liquid strontium solutions; created for hobbyists maintaining multiple reef aquaria.
  • Formulated by a marine scientist.
It is recommended that the strontium concentration in the aquarium be determined by using an accurate test kit prior to supplementing. Do not add this product directly to an aquarium containing live animals without first diluting in water as directed.

Technical Background
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. Once the rate of strontium uptake in the aquarium has been determined, the proper dosing rate of this product can be easily calculated.

Instructions and Guidelines
Basic : Dissolve 1 gram (~¼ teaspoon) of product per 40 US-gallons of aquarium water in 8-fl. oz. of fresh water; add every other day or as needed to maintain the strontium concentration within a range of 8 - 12 ppm. When used in this fashion, 1,200 g treats up to 48,000 US-gallons (181,700 L).
Advanced: Create a stock solution by dissolving 2 grams (~1 teaspoon) of Strontion-P in 8-fl. oz. of fresh water (preferably purified); each ml of the solution will increase the strontium concentration (”[Sr2+]”) in 1 US-gallon (3.785 L) of water by 0.75 ppm. [Reference: Each g of Strontion-P will increase the [Sr2+] in 1 US-gallon (3.785 L) of water by 143 ppm.] If initial [Sr2+] in aquarium is below 412 ppm, add stock sol’n at maximum rate of 10 ml per 20 US-gallons daily until desired [Sr2+] is attained, then dose daily or weekly as needed (see below). Maintain [Sr2+] within a range of +/-2 ppm. Once desired [Sr2+] has been acquired, measure aquarium`s [Sr2+] at the same time each day over a one- to two-week period to determine the daily rate of strontium uptake (i.e. the decrease in strontium). To determine daily dosing rate (preferable to weekly dosing): estimate volume of water in entire aquarium system (US-gal.); divide the daily decrease in [Sr2+] by 0.75; multiply this number by volume of water in system to obtain daily ml of stock sol’n required to maintain stable [Sr2+].

Caution: Keep out of reach of children. Not for human consumption.
