Key Features

  • Strontium Supplement
  • For use in Marine Aquariums
  • Can also be used in reef aquaria
  • Safely raises strontium levels
  • Helps corals to grow and open more.


Strontium is required for formation of aragonite in marine aquariums. It accounts for 1% of its weight, but some of it can be lost through precipitation.

Reef Basis Strontium is a high quality maximum strength ionic supplement which is designed to safely raise these levels in a marine environment. It provides essential strontium for increased growth rates in coral, coraline algae, crustaceans and many other marine organisms.

With regular use of the liquid solution, corals will open more, resist bleaching and skeletal rejection better.

It contains no acetate, gluconates, polygluconates or other unnecessary organics to pollute your aquarium. It is phosphate and silicate free. May be used simultaneously with Kalkwasser.


Continuum recommends that you maintain a strontium level of between 8 and 13 mg/L (ppm), a calcium level of between 410 and 450 mg/L (ppm), an alkalinity level of 7 to 11 dKH (2.5 to 4 meq/L), and a magnesium level of 1250 to 1350 mg/L (ppm).

Note: Aquarists keeping SPS corals should consider keeping alkalinity at 7 to no more than 9 dKH (2.5 to 3.21 meq/L).

Do not add Reef Basis Strontium to buffering (alkalinity) products.


250ml treats 2080 gallons

Shake well prior to use. Add 1 capful (5 ml) per 41 gallons (200 L) of marine aquarium water 3 to 4 times per week.

For best results, measure the strontium concentration and add as required to maintain the concentration between 8 and 13 mg/L.
