5 Best Marine Aquarium Salt Mixes (Reviews) in 2019
1. Instant Ocean Sea Salt for Marine Aquariums
The Instant Ocean Sea Salt mix is one of the more popular choices among both hobbyists and public aquariums. Unless you live by the ocean and can collect water straight from it (which wouldn’t actually be a good idea because of the potential contamination), you need to find a way to create an environment similar to the natural habitat of your marine species.
While oceans are indeed salty, they don’t just contain common salt or sodium chloride (NaCl), but also a mix of many other types of salts such as magnesium chloride and sodium sulfate, as well as trace elements. The best part about the Instant Ocean Sea Salt is the fact that it can recreate water that’s practically identical to that from the ocean, thanks to the carefully designed formula which contains precise amounts from each chemical element required.
This product is enough to make 200 gallons of saltwater at the recommended SGR or specific gravity range between 1.020 and 1.024.

Our Comprehensive Buying Guide
Creating your own aquarium and replicating the perfect conditions for corals can be extremely tricky if you don’t know which type of salt to use. If reading countless marine aquarium salt mix reviews is not an option for you due to lack of time, then you’re in luck, as we have created a short guide just for you.
We will go through the basics of synthetic sea salt and teach about the difference between commercially available products so that you get to buy the perfect one for your needs.
Why table salt won’t do
You might wonder why you can’t just get a pack of table salt from your kitchen cabinet and create your very own ocean salt rather than paying top dollar for a commercial product. The thing is that sea water doesn’t contain just table salt – or sodium chloride as it is also called. Seawater is actually a mix of many different types of salts such as magnesium chloride, sodium sulfate, potassium sulfate and bromide, strontium chloride as well as countless chemicals in minute quantities, also called trace elements.
Not only is the formula for seawater extremely complex, but even if you had all other ingredients, you still couldn’t use table salt since it can contain unspecified anti-caking agents which could either harm your fish and corals or impede their growth.
The main types of synthetic sea salt
Even when it comes to commercial salt mixes for sale, not all products are equal. Some are optimized for certain fish species, others are better suited to corals and algae. Synthetic salts targeted at corals may contain more calcium and carbonate salts while fish-specific salts can differ in concentrations of trace elements.
Even when it comes to salts manufactured for a specific category of animals you can still find differences. For example, some coral reef mixes only contain salts and trace elements while others can include vitamins, hormones and even probiotic bacteria.
Read product specifications before buying
You also need to look at product recommendations to see which salt is best for your needs, as you are probably going to want the water to have a specific gravity or a certain pH value which can be slightly higher or lower depending on the target species. Last but not least, you need to remember that even though many commercial brands advertise their mixtures as being the perfect salt, the best product will actually be the one that’s most appropriate for the marine species you intend to keep in the aquarium.
So read specifications before you buy, and don’t forget to check our list of top products and recommendations.
