Restore the true essence of the ocean in your home aquarium. BPK Pro Reef Sea Salt is a high-purity, professional-grade marine salt designed for the most demanding reef hobbyists. While standard salts focus only on Big Three (Calcium, Magnesium, KH), BPK Pro Reef prioritizes the 70+ essential trace elements found in natural coral reefs, ensuring your corals don't just survive—they thrive with natural vitality.
BPK has revolutionized their production process to deliver a salt that is cleaner, faster-dissolving, and more chemically consistent than ever before.
Macro & Trace Precision: Contains over 10 Macro elements (Sodium, Calcium, Potassium) and more than 60 micro-trace elements including Cobalt, Iodine, Manganese, and Strontium.
Ultra-Low Impurities: Utilizing newly discovered high-purity raw materials to ensure near-zero Nitrates (NO3) and Phosphates (PO4).
Enhanced Solubility: New production line technology ensures a perfect, stable mix that dissolves completely without leaving residue or cloudiness.
Laboratory Certified: Every single batch undergoes rigorous testing and certification before leaving the factory to ensure total consistency.
At BPK, we don't just claim quality—we prove it. Our Upgraded Pro Reef Salt formula has undergone rigorous independent testing to ensure that every bucket meets the strict requirements of modern reef-keeping.

By checking our Triton Lab Results, you can verify that BPK Pro Reef Salt contains:
Zero Detectable Heavy Metals: No Copper, Lead, or Tin that can harm delicate invertebrates.
Consistent Trace Elements: Verified levels of Manganese, Cobalt, and Vanadium—elements often missing in cheaper synthetic salts.
Purity of Raw Materials: Confirmation that our upgraded formula provides a clean slate for your dosing regimen.
Pure Water First: Always use high-quality RO or RODI water in a clean, non-toxic container.
Add Salt to Water: Slowly pour roughly 35-40 grams of BPK salt per liter of water. Note: Never add water to salt to prevent precipitation.
Mix & Measure: Stir thoroughly until the water is crystal clear. Always verify the salinity with a Refractometer to reach a target of 1.025 (35PPT).
Use Promptly: For maximum elemental stability, it is recommended to use the freshly prepared seawater shortly after it has fully dissolved.
Never pour dry salt directly into an aquarium containing live animals. Always mix in a separate container first.
Precision matters! To ensure your BPK Salt reaches the perfect 1.025 Specific Gravity, we recommend using the Red Starfish Seawater Refractometer for laboratory-grade accuracy during every water change.
