Reef Crystals Salt Mix

Formulated to Encourage Coral Growth

• Formulated Specifically for Reef Aquariums
• Includes Extra Calcium for Coral and Coralline Algae Growth
• Enhanced with Trace Elements and Vitamins to Support Corals, Anemones, and Invertebrates
• Neutralizes Trace Heavy Metals Often Found in Tap Water

Reef Crystals is designed to give reef aquariums a boost beyond what standard sea salt mixes provide. By increasing the concentration of key elements, it helps create conditions that support fast coral growth and vibrant coloration. The added calcium encourages strong skeletal development in stony corals and coralline algae, while a balanced mix of trace elements and vitamins promotes long-term health for corals, anemones, and other invertebrates.

What is the difference between Instant Ocean Sea Salt and Reef Crystals?

Instant Ocean Sea Salt: Engineered to closely match natural seawater.

Reef Crystals: Enriched to facilitate the growth of corals and other invertebrates in a reef aquarium.

BRS Salt Mixing Tips

Mixing saltwater is one of the most basic but important parts of maintaining a healthy reef aquarium. We’ve mixed hundreds, probably thousands, of batches over the years and have learned a few things that make the process quick, consistent, and easy to repeat.

1. Gather your supplies. You’ll need a clean Brute container or 5-gallon bucket(s), RO/DI water, salt mix, a small pump or powerhead, a small 50-watt heater, measuring cup or kitchen scale, and a refractometer or digital salinity tester.
2. Fill the container/bucket with RO/DI water. Leave a little room for the salt without overflowing.
3. Add the pump and heater, then plug them in to start circulating and warming the water.
4. Slowly add salt to the bucket as the water circulates. As a general rule, about 1/2 level cup per gallon will get you close to the target salinity without going over.
5. Let the salt fully dissolve, then check the salinity. Your goal is around 1.025 specific gravity (~34 ppt) for a mixed reef.
6. Adjust if needed. Add more salt if it’s too low, or a bit of RO/DI water if it’s too high. Give it time to mix fully between adjustments for accurate readings.

Tip: For consistent results, use an inexpensive kitchen scale to weigh your salt in grams instead of relying on measuring cups. For Reef Crystals, that's about 155 grams per gallon to achieve a 1.025 specific gravity (~34 ppt).

Important: NEVER mix salt in an aquarium containing animals.
