Aquariums rely on salt to function, and without it, your fish will suffer. So what is salt, and why is it essential for aquariums? Salt is a mineral that helps regulate the water’s pH level. Unfortunately, too much of one type of salt can make the water too alkaline or too acidic, impacting the health and survival of your fish. In addition to its role in aquariums, salt is also used in many other areas of life – from food production to industrial processes.
Aquarium salt and sea salt are both types of salt, but they have different properties and uses. Aquarium salt is more common and enriches the water in an aquarium. Sea salt is saltier and is used as a seasoning or to add flavor to food.

How Does Salt Work In Your Aquarium?
Saltworks help keep calcium and magnesium levels in the water where they belong as mineral integrators. Combined with other minerals, it also helps create an acidic environment conducive to fish growth and reproduction.
Aquarium salt is a mineral supplement used to make freshwater and saltwater fish tanks more alkaline. The high concentration of chloride ions in aquarium salt helps control pH levels and keep your tank clean. Aquarium salt can also be used as a food additive or help prevent algae growth.
Sea salt is a type of salt used as a mineral supplement for fish tanks. It contains lower concentrations of chloride ions and is, therefore, less effective at controlling pH levels or preventing algae growth. Sea salt can be used as a food additive or add flavor to your aquarium water.
Is Aquarium Salt and Sea Salt the Same?
Aquarium salt and sea salt are not the same. Sea salt is a mineral salt that comes from the sea and has a higher concentration of chloride ions than aquarium salt. Additionally, sea salt is colorless and lacks the taste commonly associated with aquarium salts.

Aquarium Salt Benefits
Aquarium salt has several benefits for fish and aquarium owners. These include:
- It maintains water chemistry and controls pH levels.
- This helps keep your tank clean and healthy, preventing the growth of algae.
- It also includes essential minerals needed by fish for optimum health.
- Aquarium salt is a mineral salt used as a food additive and disinfectant.
- It also treats aquarium fish diseases, such as fin rot. Aquarium salt has a higher concentration of chloride ions than sea salt and is, therefore, more effective in treating fin rot.
- Aquarium salt is also used as an Ich inhibitor. Aquarium salt binds with minerals in the water to form insoluble scums, which suppress the growth of Ich.
When to Use Aquarium Salt?
Aquarium salt can make freshwater and saltwater fish tanks more alkaline. This helps control pH levels and keep your tank clean. Aquarium salt also acts as a food additive to help prevent algae growth. Use aquarium salt when you first set up your tank, at regular intervals during the year, or if your water becomes too acidic or salty. It can be used when starting a new aquarium or when the water becomes too hard to maintain proper pH levels.
When to Avoid Aquarium Salt?
Salt is a common additive in aquariums because it helps to keep the water clean and healthy. However, some people avoid using salt in their tanks because they believe it can harm fish. There is no scientific evidence that using salt in an aquarium harms fish, but some hobbyists choose to avoid using it.
Aquarium Salt Substitutes
Some of the most popular substitutes include marine salt, rock salt, and Epsom salts. Choosing a suitable replacement for your particular aquarium setup and fish species is essential. In addition, some salt substitutes may affect your fish’s health.
Other Types of Salt You Can Use as Substitutes
You can also use table salt, kosher salt, and Redmond Sea Salt as substitutes for aquarium salts. Table salt is “sodium chloride,” and kosher salt is a mix of potassium chloride, magnesium chloride, and calcium sulfate (it’s essential to read the label to be sure). In addition, Redmond Sea Salt contains trace amounts of copper and manganese.
How Much Aquarium Salt per Gallon of Water?
The recommended dosage of aquarium salt per gallon of water depends on the specific substituent used. However, most substitutes recommend a dosage of 1 teaspoon per gallon of water. Additionally, you should always follow any directions provided by the salt manufacturer.
How Much Aquarium Salt for Brackish Water?
You can also use aquarium salt to adjust the salinity of salty water. Brackish water is water that contains a small amount (less than 25%) of freshwater. To change the saltiness of your brackish aquarium, add 10 grams of aquarium salt per liter of water. In addition, aquarium salt is an excellent product to use when you are running your fish tank in a bucket filter.

Sea Salt Benefits
Sea salt has many benefits for both your fish and the environment. First, it helps to regulate the pH level of your aquarium, which is essential for healthy water chemistry. Additionally, sea salt contains minerals that are beneficial to fish health. These minerals include calcium, magnesium, potassium, and sodium. And finally, adding sea salt can also help reduce plant growth in tanks with the substrate (e.g., live rock or granite).
Sea salt is also beneficial to your plants! Plant roots need a constant supply of minerals and trace elements from the water. However, most fish medications in home aquariums are made with unnecessary amounts of ammonia that can alter the coloration and appearance of aquatic plant leaves. Fortunately, sea salts containing no ammonia or other chemicals will harm aquatic plants. Instead, they directly provide these essential mineral nutrients to the plant roots without breaking pH levels and fish.
When to Use Sea Salt?
You can use sea salt in freshwater and marine aquariums and adjust the salinity of salty water. Sea salt is also an excellent product when running your fish tank in a bucket filter.
When to Avoid Sea Salt?
Do not use sea salt in an aquarium that contains tropical fish, as it can cause serious illness. In addition, do not use sea salt with corals, as the increased salinity will kill them.
How Much Sea Salt per Gallon of Water?
When adding sea salt to your aquarium, it is essential to use the correct amount. For example, one tablespoon of sea salt per gallon of water will adjust the salinity level in your aquarium.
