Description
The Tropic Marin Pro Reef Sea Salt 25kg Bucket + FREE ICP Test is a premium, pharmaceutical-grade reef salt designed for serious marine aquariums where stability, coral growth, and precision water chemistry are the priority.
This larger 25kg bucket size is the high-efficiency option, making up to approximately 750–800 litres of seawater, and is widely used in reef systems due to its consistent parameters and clean mixing properties.
Key Features & Benefits:
- Complete reef-optimised formulation – balanced calcium and magnesium to support strong coral growth
- Stable alkalinity (KH ~7–8 dKH) – designed to maintain long-term parameter stability
- Ultra-pure pharmaceutical-grade salts – free from nitrates and phosphates
- Clean mixing – dissolves fully with minimal residue or clouding
- Natural seawater balance – includes all essential trace elements in correct ratios
- FREE ICP test included – allows professional-level water analysis for precision reef management
Why reef keepers choose it:
This salt is designed specifically for modern reef systems, especially SPS/LPS coral tanks where consistency is critical. It helps reduce parameter swings, supports calcification, and is often used in both new setups and long-term maintenance systems.
Care & Usage Tips:
- Mix with RO/DI water at 25°C
- Always add salt to water, not water to salt
- Target salinity: 1.025–1.027
- Fully dissolve and aerate before use
Specifications:
- Size: 25kg bucket
- Yield: approx. 750–800 litres
