ELEMENTALS Ca+Sr is a highly concentrated calcium/strontium solution used for compensating calcium and strontium deficiencies in reef aquariums.

Calcium, along with carbonate, is the essential building block for the growth and development of coral skeletons and invertebrates.

We recommend maintaining Ca between 380 – 420 mg/L (at 35 salinity) and testing regularly with a laboratory water analysis.

Dosage of Elementals Ca + Sr:
50ml per 100L (26 US gal) = 95 mg Calcium
50ml per 100L (26 US gal) = 1.8mg Strontium

Optimal calcium value: 380 – 420 mg/L
Optimal strontium value: 8 mg/L

Maximum daily dose: Do not increase Ca by more than 25ml/100L per day.
