ELEMENTALS Ca/Sr - Calcium/Strontium 1000 ml

Fauna Marin ELEMENTALS Ca+Sr is a concentrated calcium/strontium solution for reef aquariums running low on either or both elements.

• Dose: 50ml per 100L (26 US gal) adds approximately 95mg calcium and 1.8mg strontium
• Maximum daily increase: 25ml per 100L
• Target range: calcium 380-420mg/L at 35 ppt salinity; strontium 7-10mg/L (8mg/L standard)
• Ingredients: water, calcium salts, strontium salts, stabilizers, biopolymers
• Format: 1000ml bottle

Calcium is the primary building block of coral and invertebrate skeletons, and strontium co-precipitates into that same skeleton structure — it helps regulate localized growth, sharpens blue coloration, and contributes to a harder, more stable skeleton. Because the two elements are bundled here, this bottle works best as a calcium top-off that happens to carry strontium along with it; for strontium correction independent of calcium demand, use ELEMENTALS Sr instead.

Includes: 1x 1000ml bottle.

Compatible with: dose via the Fauna Marin DIY Doser adapter; use ELEMENTALS Sr alone if strontium needs correcting without adding calcium; confirm levels with a Fauna Marin ICP water test.
