Fauna Marin Professional Sea Salt 25 kg Bucket – Approx. 200 Gallons

Fauna Marin Professional Sea Salt is a 25 kg marine aquarium salt mix for reef keepers maintaining sensitive SPS, LPS, and mixed-reef systems. This heavy-duty bucket yields approximately 200 US gallons (750 L) of saltwater and is formulated for hobbyists, advanced reef keepers, and commercial coral-farming applications.

The formulation uses pharmaceutical-quality raw salts and provides macro elements plus bioactive trace minerals. It is designed to replicate natural reef water chemistry with balanced calcium, magnesium, and alkalinity ratios. At 35 PSU (1.026 SG), typical targets are approximately 8.0–8.5 dKH alkalinity, 420–440 mg/L calcium, 1300–1350 mg/L magnesium, and 390–410 mg/L potassium.

Each batch is independently laboratory tested for consistent parameters and is described as free of unwanted nitrates, phosphates, synthetic chelators, and heavy-metal contamination. The mix is designed to dissolve rapidly in RO/DI water without residual film, cloudiness, or heavy precipitate, and it can be used with Zeovit, Balling Light, Triton, and standard probiotic or carbon-dosing setups.

For mixing, begin with purified RO/DI water at 68–77°F (20–25°C) and circulate it with a powerhead. Slowly add about 38–40 grams per liter, or roughly 1/2 cup per US gallon, until reaching 35 PSU (1.026 SG). Allow the water to circulate until clear and fully dissolved, typically 15–30 minutes, then verify that temperature and salinity match the display aquarium before a water change.
