- Strontion-P - Dry Strontium Supplement - Brightwell Aquatics
- High-purity powdered strontium.
- Incorporated by corals, clams, and other reef-building invertebrates into aragonite, themineral 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.
Instructions and Guidelines
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).
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+].
Keep out of reach of children. Not for human consumption.
Strontium (min) 54% (540,000 ppm)
Strontium chloride (anhydrous)
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
Trying something new By Gerardo on 9/4/2018Gerardo would recommend this product to a friendI was buying this already mixed in liquid form, but I bought this to mix my self and save a few bucks and it's great!!! I'm going to keep buying this for sure!
Good Bang for the Buck By DG on 11/2/2016DG would recommend this product to a friendI do near zero water changes and have my water tested from Triton. Using the Triton Strontium for my 180g lasts 8 month at a cost of $42 a bottle. Using this dry supplment mixing 1/3 cup per gallon of ro/di and dosing 150ml per month this will last me 2 years for just $20. I looked into HW Strontium since I aslo use the HW trace elements and pleased with them but for my 180g tank $18 and would only last 2.5 months.
If your doing water changes though you likely don't need to supplement Sr at all. Instant ocean tests out above natural levels is enough to maintian with just water changes.

Does the strontium-p product contain anything other than just strontium? For example any other trace minerals, manufacturing chemicals, or any other additives?
