Choosing the best salt for the reef tank requires quite a bit of research to determine the right salt mixture for your coral. It is important to note that every reef tank needs a different kind of salt mixture to achieve ideal parameters.
Salt is also an essential part of the reef tank maintenance just because salt can affect your coral’s health and its ability to grow and become strong.
There are different salt combinations for your reef tank, and finding the best salt is crucial for creating a healthy environment for all creatures. Reef ecosystems are exceptionally delicate, and minor water changes can have enormous implications for their health.

Since we are dealing with slightly delicate creatures, you must know what salt to choose for different types of inhabitants. There are a few key things that you should be looking for to select the best reef salt for the perfect environment.
Three Most Important Things
There are three most essential components that you should be looking for when you are choosing your salt mix, and they are calcium, magnesium, and alkalinity.
By adding salt to the water in your tank, you are enriching it with less abundant chemicals that can be found in natural seawater. Even though seawater is known for its salt, it contains many different elements that cannot be replicated by adding sodium chloride – standard table salt.
Calcium: Corals and invertebrates use calcium to build their stony skeletons. You should be aiming for 400ppm (parts per million) calcium concentration to provide a healthy environment.
Alkalinity: This is related to the amount of bicarbonate in your water, and it is essential just because natural seawater has a pH greater than 7. Without alkalinity in the form of bicarbonate, your tank water will turn acidic enough to dissolve skeletons of corals and poison your fish. Alkalinity has a recommended range of 8-11 dKH.
Magnesium: Magnesium is a trace mineral that can be found in natural seawater. This means that it is located at extremely low abundances relative to chemicals like chlorine or sodium. Magnesium is used for keeping alkalinity balanced. In other words, in interacts with bicarbonate to prevent it from precipitation as calcium carbonate.
Magnesium also has a recommended range of 1250-1400 ppm.
Reef Salt vs Marine Salt
When we compare reef salt vs marine salt, you can find that reef salt has more profound levels of elevation in the process of making. It contains higher calcium, magnesium concentration, and iodide than the marine salt.
Both have some similarities, and they will work fine for your saltwater inhabitants, you just have to choose which one is better for you.
Cost per gallon
To choose the best reef salt, you need to keep the price in mind. Just because different products have different levels of necessary elements, you cannot look at the cost of the product.
If you want to choose the best salt for your money, you need to look at the cost per gallon. This is very simple to calculate as any standard box of salt is for 150 to 200 gallons of water. You can simply divide the number of gallons per bucket to the price of the product.
For example, $50 can make 150 gallons of saltwater. When you divide 50 by 150, it gives you a total cost of $0.33 per gallon.
What’s living in your aquarium?
Determining what type of creatures you are going to have in your tank will impact your decision when choosing your salt.
Even though reef salts mixes are very similar to one another, they are still developed with different levels of calcium, alkalinity, and magnesium. Some reef sand mixtures have higher concentrations of salt and others higher or lower on magnesium.
Every inhabitant in your aquarium requires different water mixture to provide a healthy environment. For example, if you choose to go for hard corals, you are going to need a salt mix with higher levels of trace elements and vitamins. And on the other hand, if you go for soft corals or fish only tank, the extra levels are not necessary.
There is a good reason for this. Hard corals are always precipitating a calcium carbonate skeleton. This means that they such out both alkalinity and calcium from your tank’s water.
If you go for the fish only tank, the balance of alkalinity is much more critical than the concentrations of magnesium in calcium, since fish don’t need that much calcium to grow.
Frequently Asked Questions
Is Sea Salt the Same with Aquarium Salt?
Aquarium salt is a typical pure salt (sodium chloride). The preparation process for aquarium salt is much easier than sea salt since it is only evaporated seawater. It does not contain artificial additives, color, sugar, or high levels of vital nutrients for saltwater inhabitants. It is used for blocking the toxic effects of nitrate to freshwater fish, improves fish breathing, and reduces stress.
On the other hand, sea salt contains a more complex and more significant number of additional elements such as calcium, potassium, sulfates, hydrogen carbonate, bromine, etc. This is going to help make the aquarium water similar to the sea, and create the perfect environment for your marine invertebrates.
They are both very different types of salt, used for various purposes.
How much salt do I put in my saltwater tank?
Many beginners struggle with optimizing the levels of salt in the aquarium. The truth is, the salt needed might vary from brand to another due to the chemistry of the product. However, in most cases, it will be 35g of salt per liter of RO water.
You can always check the label for the instructions from the manufacturer.
How do you make a saltwater fish tank?
There are a few steps before you can create your saltwater fish tank.
- Buy your sea salt mix
Depending on the type of creatures, and the nutrient specifications you want to go, you should choose your sea salt mix.
- Decide your water source
The water source that you will use in your aquarium is also essential. Using tap water is only useful if you use the fish only tank. If you are going for a reef tank, you should use deionized water (RO)
- Mix the water with salt
You should then rinse the container to ensure you have nothing to contaminate your saltwater. Then fill the box with RO/DI or tap water. Place a thermometer to ensure you have the perfect temperature of 72-80 degrees Fahrenheit for fish-only tanks, and 75-78 degrees Fahrenheit for a reef tank. After the temperature check, you can add your seawater mixture slowly and stir it.
