ELEMENTALS Sr - Strontium 1000 ml

Fauna Marin ELEMENTALS Sr is a highly concentrated strontium solution for correcting strontium deficiencies in reef aquariums, independent of calcium.

• Target range: 7-10mg/L, with 8mg/L as the standard reference (matching natural seawater); keep below 12mg/L
• Dosing scales with calcium consumption — Fauna Marin recommends adjusting in roughly 10% increments against your existing calcium/Balling Trace 1 dosing rather than a fixed ml-per-100L figure
• Format: 1000ml bottle

Strontium co-precipitates into the coral skeleton alongside calcium, where it helps regulate localized growth patterns, enhances blue coloration, and — combined with organic compounds — contributes to a harder, more stable skeleton; it also supports parasite defense in coral tissue. Reach for this standalone bottle when an ICP test shows strontium running low on its own even though calcium is fine — a case ELEMENTALS Ca/Sr's combined dosing can't correct without also pushing calcium higher than needed.

Includes: 1x 1000ml bottle.

Compatible with: dose via the Fauna Marin DIY Doser adapter; use ELEMENTALS Ca/Sr instead if both calcium and strontium are low together; confirm levels with a Fauna Marin ICP water test.
