Design & Build Quality
The granular form of Reef Crystals offers several advantages over other salt forms. The granules dissolve quickly and completely, leaving no residue or undissolved particles in your mixing container or aquarium. This consistency ensures that all the essential elements are properly distributed throughout the water.
The packaging is designed to maintain the integrity of the salt mix. The container is sealed to prevent moisture absorption, which can cause the salt to clump and affect its performance. The granules themselves are uniform in size, which contributes to even dissolution and consistent mixing.
Materials & Construction
The composition of Reef Crystals is where it truly excels. Unlike basic sea salt mixes that simply replicate natural seawater, this product is formulated with elevated levels of essential reef elements. The extra calcium is particularly noteworthy, as it directly supports the growth of stony corals and coralline algae, which are the foundation of many reef aquariums.
The trace elements included in the formula are carefully balanced to support the diverse needs of reef inhabitants. These elements, while required in smaller quantities, are crucial for the health and growth of corals and other invertebrates. The addition of vitamins further enhances the product’s ability to support aquatic life in a captive environment.
Performance
In real-world use, Reef Crystals delivers consistent and reliable performance. The salt mixes quickly and completely, producing clear water that’s ready for use in your reef aquarium.

Color Enhancement
Many trace elements contribute to the vibrant colors displayed by corals and other invertebrates. Elements like strontium, iodine, and various metals are essential for pigment production and overall health. The comprehensive trace element profile in Reef Crystals helps maintain and enhance the natural colors of your reef inhabitants.
Extra Vitamins
Growth Support
Vitamins play important roles in the growth and development of aquatic organisms. In a captive environment, where natural food sources may be limited, supplemental vitamins can help ensure that your corals and invertebrates receive all the nutrients they need. The extra vitamins in Reef Crystals support growth, reproduction, and overall health.
Stress Reduction
Vitamins can also help reduce stress in aquatic organisms, particularly during times of environmental change or when introducing new specimens to your aquarium. The vitamin supplementation in Reef Crystals helps support the health and resilience of your reef inhabitants, allowing them to better adapt to captive conditions.
Heavy Metal Detoxification
Tap Water Safety
Many municipal water supplies contain traces of heavy metals like copper, lead, and zinc, which can be harmful to aquatic life. The detoxification properties of Reef Crystals help neutralize these contaminants, providing an additional layer of protection for your reef aquarium.
Long-Term Stability
By detoxifying heavy metals, Reef Crystals helps maintain long-term stability in your aquarium. This is particularly important for reef tanks, where sensitive corals and invertebrates can be adversely affected by even low levels of certain metals. The heavy metal detoxification feature contributes to the overall health and longevity of your aquatic ecosystem.

If you notice any clumping, it’s a sign that the salt has absorbed moisture. While small clumps can often be broken up and used, extensive clumping may indicate that the salt has been compromised and should be replaced.
Maintenance Tips
Regular water changes are essential for maintaining a healthy reef aquarium. Using Reef Crystals for these changes helps ensure that your tank receives a consistent supply of essential elements. Aim for weekly water changes of 10-20% of your tank’s volume, depending on your bioload and the specific needs of your coral and invertebrate inhabitants.
Monitor your water parameters regularly to ensure they remain within the optimal ranges for reef aquariums. While Reef Crystals provides a solid foundation, you may need to supplement with additional calcium, alkalinity, or magnesium to maintain the precise levels required by your specific coral species.
Troubleshooting Tips
If you notice inconsistent parameters after mixing Reef Crystals, ensure you’re following the proper mixing procedure. Use reverse osmosis/deionized (RO/DI) water for best results, and mix the salt thoroughly to ensure all granules are fully dissolved. Incomplete mixing can lead to localized areas of high or low salinity.
Should your calcium levels drop between water changes, consider supplementing with a calcium additive. While Reef Crystals provides extra calcium, very demanding reef tanks with numerous stony corals may require additional supplementation to maintain optimal levels.
If you experience algae outbreaks, it may be a sign of excess nutrients. While Reef Crystals provides essential elements, it’s important to maintain a balance. Ensure you’re not overfeeding your tank and that your filtration is adequate for your bioload.
If your corals show signs of stress or poor growth, test your water parameters to ensure they’re within the proper ranges. While Reef Crystals provides a good foundation, factors like lighting, flow, and water quality can all affect coral health.
