## Description

Product Description               No matter the size of your aquarium, Instant Ocean sea salts and water care products offer the smartest, easiest way to bring the ocean home. Our scientifically formulated sea salts are used exclusively by many of the leading large-scale aquariums and research facilities across the country. Instant Ocean Reef Crystals Reef Salt is formulated especially for use in reef aquariums. It contains essential ocean reef elements in concentrations greater than those found in natural sea water. Extra calcium encourages the growth of large and small polyp stony corals (LPS and SPS) as well as coralline algae. Extra trace elements provide an additional measure of vital nutrients, and extra vitamins help to promote vigorous growth and survival of corals, anemones and other invertebrates in a captive environment. Neutralizes traces of heavy metals often present in tap water. Mix Instant Ocean Reef Crystals Reef Salt with ordinary dechlorinated tap water – use ½ cup per gallon of water. Stir vigorously to ensure a good mix. Use immediately or aerate the water until it achieves oxygen/carbon dioxide equilibrium. See product label for complete use directions. Instant Ocean offers a full line of products, including sea salt, water treatments, test kits and accessories, to make sure your saltwater aquarium remains vibrant and healthy.

                        Directions               1. Mix Reef Crystals with ordinary dechlorinated tap or purified water.To prepare small quantities, use 1/2 cup of Reef Crystals per each U.S. gallon of water. Mix as directed. 2. Stir vigorously to ensure a good mix. Although the Reef Crystals solution may be used immediately, we suggest aerating the water until it achieves oxygen/carbon dioxide equilibrium. 3. Measure specific gravity with an Instant Ocean® Hydrometer.Recommended Specific Gravity Range: 1.020-1.026 at 77°F. 1.4 lbs of Reef Crystals is formulated to create 5 gallons of saltwater at a specific gravity of 1.021. 4. Adjust salt level accordingly. If specific gravity is too low, add more Reef Crystals. lf too high, add more dechlorinated water. Change 20% of aquarium water every two weeks to maintain optimum water quality             See more

## Questions & Answers

**Q: Can this be used in a jellyfish tank?**
A: If your fish or whatever you have live in saltwater  then yes it can be used.

**Q: Why do the pictures say all 25 gallons when i selected 50?**
A: Im going to say that they just used the same stock photo for 10, 25, and 50 gallon packages rather than having to find 3 different pictures. If you ordered the 50 gallon, im sure you'll get the 50 gallon.

**Q: When is the expiration  date?**
A: I checked the box it came in and I don't see any expiration date on it. I see 142005 but that could just be the shipping people putting something on the box. I had a bad experience with this salt didn't think salt expired but maybe that is why I had trouble with it.

**Q: how is this different than instant ocean purple box?**
A: Hi Jimmy Choo, 

Reef Crystals starts with Instant Ocean as the base salt but we add additional trace elements, calcium, magnesium, strontium, etc. to it for the corals.  It also will chelate any heavy metals that are in your source water (assuming you are using tap water and not RO water, that is).
