Salifert Strontium Test
The Salifert Strontium Test Kit provides you with an easy way to test strontium in the aquarium. In a marine aquarium strontium plays an important role in accelerating the growth of coral and calcareous algae. Natural sea water contains approx. 7 – 9 mg/L strontium. Strontium is very difficult to test for, but if there is found to be a depletion of calcium in the aquarium then strontium levels are likely to be very low as well. It is advisable to maintain a strontium concentration of between 5 and 20 mg/L.
