Best Reef Salt Mix in 2021: Reviews with Comparisons
Best Reef Salt Mix
When we think of seawater, we imagine water with high salt content. After all, that’s the big difference between seawater and freshwater, isn’t it? However, natural ocean water is also high in other minerals and nutrients fish need and can buffer water against rapid changes. Aquarists know that if you want healthy saltwater fish, you can’t simply add table salt to water – you need a professional reef salt mix. But which one is the best reef salt mix? Let’s find out.
Best Reef Salt Mix Reviews
Instant Ocean Sea Salt for Marine Aquariums
Instant Ocean has been a favorite name in reef salt mixes for decades, and many aquarists swear by this mix. The scientifically formulated blend contains every element that marine fish and invertebrates need to grow and thrive. Therefore, you don’t need to add any supplements.
In addition, it quickly achieves and buffers the right pH balance and is free of nitrate and phosphate.
Instant Ocean Sea Salt dissolves quickly, with a crystal-clear, ready-to-use solution in just minutes. Plus, it is well-packaged to exclude moisture.
The balance of elements and nutrients in reef salt mixes is vital. Unusually, a brand with the reputation of Instant Ocean does not clearly publish critical parameters like salinity, calcium, pH, magnesium, etc.
While many hobbyists have researched and tested the elements in this reef salt, it is unusual that the company does not do so.
Because the exact parameters of this mix are unclear, a beginner may want to choose a different reef salt mix until they have more experience measuring, mixing, and monitoring a reef aquarium.

It contains 425-450 ppm calcium, 1150-1250 ppm magnesium, with a pH of 8.2 and a specific gravity of 1.021-1.0123. When mixed to a specific gravity of 1.024 for reef aquariums, calcium and magnesium levels rise accordingly.
Kent Marine Saltwater Aquarium Salt Mix is manufactured with micro-processing so every container has the correct ingredients. Ingredients are selected for purity, consistency, and solubility, and it is free of nitrates and phosphates.
When choosing an aquarium reef salt, here are the key features to look for:
All reef salts provide calcium and magnesium. They also provide other trace minerals, and increase alkalinity in a reef tank. They replace the need to supplement these elements individually by pre-mixing them.
Nothing is more harmful to your aquarium than sudden changes in water chemistry. Therefore, Aquarium reef salts need to be consistent, from the first opening of the package to the bottom and from package to package. To ensure consistency, here are a few things to look for:
Elements that have been manmade in a laboratory are purer and more consistent than elements that have been evaporated from natural seawater. Thus, while natural seawater evaporation may seem more organic and healthier, it may not be consistent.
Uniform Particle Size
Reef salts are processed so that all the ingredients in the mix are the same size as the particle. This helps the components mix more evenly in the package without larger or heavier particles settling on the bottom. It also helps the salts dissolve more quickly and uniformly in water for faster and safer use.
High-quality reef salts are tested after processing. This ensures every batch meets the manufacturer’s standards. Small batches, lot labeling, and testing all help ensure consistency.
Look for reef salts that aquarists have been successfully using for years, rather than opinions based on a single package.
Mixing at Home
When you use reef salts, mix them when you receive them and before every use to ensure that all the elements are distributed evenly throughout the package.
Because aquarium salts are, well, salts, they will fuse into a single large lump of salt if exposed to moisture. Look for packaging that keeps the product sealed and dry from the warehouse to your door.
Composition for Your Aquarium Inhabitants
While there are many factors to consider based on how you stock your saltwater tank, the most significant factor to pay attention to is whether and what type of corals you have.
Hard corals require higher amounts of calcium and carbonate and benefit from calcium-rich, very alkaline water.
Soft corals require less calcium, and some fish prefer water that isn’t as alkaline. You can always choose supplements that add the desired nutrients to your water.
Choose the calcium levels appropriate for your aquarium, whether you have hard corals, soft corals, invertebrates, or fish only.
What’s the Difference Between Reef Salt and Reef Crystals?
The truth is, these terms can be confusing because they are often used in the same way. Reef salt is designed for healthy fish-only saltwater tanks. Reef crystals are intended to foster other invertebrates’ growth in a reef tank.
Therefore, if you use reef salts in a reef tank, you may need to add other elements to support the growth of corals and other reef organisms.
What’s the Difference Between Reef Salt and Aquarium Salt?
To make the names even more confusing, “aquarium salt” is simply pure sodium chloride with no other minerals or elements. In contrast, “reef salts” are salts that give fresh water all the minerals and elements found in seawater.
Aquarium salts can treat certain health problems in freshwater fish. However, it cannot create healthy water for saltwater fish.
