We've all seen the fantastic aquariums on shows like “Tanked” and dreamed of creating our own bit of tropical paradise in our homes. Reef aquariums can be a beautiful and soothing presence, but many owners struggle with maintaining livable conditions in the tank. One of the most important factors in keeping a tank alive is the best reef salt.
Coral requires safe levels of calcium, magnesium, and strontium, and modern reef salt is designed to help reef aquarium owners keep conditions at optimum levels. But there are a lot of options out there, and finding the best reef salt for your tank can be a challenge. We're here to help take the stress out of that decision with our review of the best reef salt for aquariums.
Best Reef Salt Frequently Asked Questions
1. What Is Reef Salt?
Coral requires saltwater to survive. Saltwater provides important chemicals like calcium and magnesium as well as the pH that coral prefers. The best reef salt recreates the chemical and alkaline conditions normally found in ocean water in aquariums so your coral stays healthy.
2. What Does Reef Salt do?
The best reef salt creates the perfect environment for growing and maintaining coral. Adding reef salt to dechlorinated tap water or purified water ensures that the coral will receive the necessary nutrients and avoid any toxic additives that might damage or destroy the coral.
3. How Does Reef Salt Work?
The best reef salt is a blend of elements that are typically found in saltwater. The major components are usually calcium, magnesium, and strontium, but manufacturers often include other trace elements so the water in the aquarium mimics ocean water as closely as possible. The exact ratio of elements varies among manufacturers, but the best reef salt should include only non-toxic, naturally occurring elements and avoid potentially harmful ingredients like nitrate, phosphate, arsenic, and beryllium.
4. Where Can You Buy Reef Salt?
Reef Salt is readily available at any local aquarium supply store. Many large pet store chains like Petco and PetSmart also sell reef salt in their stores. Petco and PetSmart also have online sites where you can order the best reef salt directly. Sites like Amazon and Wal-Mart are other options for ordering reef salt online.
5. How Do I Know Which Reef Salt Is the Best Reef Salt for My Aquarium?
Choosing the right reef salt can be difficult. Some reef salt is only for specific types of coral, while others are more general and suitable for a wide-range of coral. Our goal with this review is to provide the information you need to select the best reef salt for your aquarium.
Finding the Best Reef Salt - What We Looked for
Several factors went in to our review for the best reef salt. The most important item is clearly the chemical component of the reef salt, but we also looked at any special features that might be offered, the pros and cons of each product, and availability. We combed through hundreds of websites to find products with a proven track record and ready availability. Any reef salt that was too hard to find or too obscure was eliminated from our research. Our finalists for best reef salt were rigorously tested and compared to find that true standout.
Price Range for Best Reef Salt
Comparing prices for the best reef salt can be tricky since there is no set of standard sized packaging. Most major manufacturers do sell a 175 gallon to 200 gallon product, and we've opted to use that as the base for our price range. Higher-end products are often designed for a specific purpose, such as accelerated growth or tank recovery and carry a higher price.
