Premium-grade marine salt formulated for natural seawater (NSW) chemistry and ultra-clean mixing. PURE uses pharmaceutical-grade base salts and balanced trace elements for stable parameters, rapid dissolution, and crystal-clear water—ideal for SPS/mixed reefs and modern low-nutrient systems.
NSW-balanced: targets realistic reef parameters for stability and coloration
Ultra-low impurities: no added nitrates, phosphates, or anti-caking agents
Fast-dissolving & clear: mixes clean with minimal residue and quick pH stabilization
Consistent batch control: tight tolerances on major/trace elements
Suitable for SPS, LPS, and mixed reefs; great for routine water changes & new setups
Alkalinity: ~7.5–8.0 dKH
Calcium: ~420 mg/L
Magnesium: ~1280–1320 mg/L
Potassium: ~380–420 mg/L
Strontium & essential traces: balanced to NSW ranges
(No measurable nitrate/phosphate when mixed with RODI water.)
Use RO/DI water, 0 TDS preferred.
Heat & circulate to 75–78 °F (24–26 °C).
Add salt slowly to the water (never water to salt).
Start at ~35 g/L (4.7 oz/US gal) and adjust to 1.025–1.026 SG (35 ppt) with a calibrated refractometer.
Mix for 1–2 hours until fully dissolved and clear; use within 24 hours for best results.
For acclimation or soft-coral systems: mix to 1.023–1.025 SG (32–34 ppt).
Match temp, salinity, and alkalinity to your display before water changes.
Store sealed, dry, and at room temperature to prevent clumping and drift.
