Red Sea Salt – Premium Natural Sea Salt for Marine & Reef Aquariums

Foundation is everything. Red Sea Salt is harvested directly from the pristine waters of the Red Sea, providing a chemically balanced, high-quality base for all marine and reef environments. Unlike synthetic salts, Red Sea Salt is solar-evaporated, preserving the natural trace elements and minerals in their original, bioavailable forms.

The Science of the Blue Bucket

Specifically formulated for mature reef systems and low-nutrient (ULNS) tanks, the "Blue Bucket" is engineered to provide the exact parameters of natural seawater. It is the ideal choice for hobbyists focusing on SPS corals or those who prefer to maintain their alkalinity at near-natural levels.

Key Features & Benefits

Natural Solar Evaporation: Harvested from the Red Sea to ensure a diverse range of trace elements that synthetic mixes often lack.
Optimal Alkalinity (7-8 dKH): Designed to match natural reef parameters, preventing alkalinity swings in sensitive coral species.
Rapid Solubility: Mixes crystal clear in minutes, allowing for quick water changes without leaving unsightly residue in your mixing barrel.
Balanced Foundation Elements: Contains the perfect ratios of Calcium, Magnesium, and Carbonates to promote healthy calcification and skeletal growth.
Nitrate & Phosphate Free: Guaranteed purity to ensure your water changes help export nutrients, not add them.

Which Red Sea Salt is right for you?

Red Sea Salt (Blue Bucket): Best for SPS-dominant reefs, Ultra-Low Nutrient Systems (ULNS), and fish-only (FOWLR) tanks where natural alkalinity levels are desired.
Red Sea Coral Pro (Black Bucket): Best for Mixed Reefs or new tanks where elevated Alkalinity (11-12 dKH) is needed to accelerate coral growth.

Typical Parameters (at 1.025 S.G.)

Element	Red Sea Salt (Blue)	Benefit
Alkalinity	7.8 – 8.2 dKH	Stable, natural pH levels
Calcium	400 – 420 mg/l	Essential for skeletal growth
Magnesium	1220 – 1280 mg/l	Prevents mineral precipitation
Potassium	375 – 395 mg/l	Enhances coral "pop" and blues

Mixing Instructions for Best Results

Use RODI water to ensure zero contaminants.
Add salt to water (never water to salt) while circulating with a pump.
Red Sea Salt is designed to be used quickly; do not mix for more than 4 hours to prevent the precipitation of carbonates.
Once the water is clear and the temperature is stable at 25°C, it is ready for your reef.
