What is Epsom Salt?

Epsom salt or magnesium sulfate is a chemical compound comprised of – oxygen, sulfur, and magnesium.

This chemical compound is often mixed up with table salt, but it’s an entirely different substance with a unique set of properties. The term “salt” is used more to describe how it looks rather than being compared to the salt humans consume.

When Epsom salt was first discovered, it was named after a small town in the heart of Surrey, England.

Ever since then, it’s been used for a slew of health-related reasons including being used in baths by humans. However, another reason that has started to become mainstream in recent years would be adding Epsom salt into fish tanks.

This has generally been frowned upon by fish experts worldwide even though it is permitted.

Epsom salt is only efficient when dealing with forms of bloating in fish.

In some cases, Epsom salt has also been used as a way to help fish feel better due to underlying health conditions, especially when aquarium salt didn’t work.

It has also been used in several human ailments such as insomnia and constipation, although these benefits aren’t medically reported nor should they be accepted as truth.

Any fish-related advantages that do come from Epsom salt have more to do with the presence of magnesium in the chemical compound. This is a nutrient that is readily available in the water, which may work for some fish.

However, this shouldn’t be taken at face value and is something to keep in mind when it comes to an “Epsom salt vs aquarium salt” comparison.

What is Aquarium Salt?

Aquarium salt is a generic term used to describe a wide array of “aquarium-friendly” salts that can be used to promote fish health.

Salt is often used as a way to increase the salinity in the freshwater tank. This is done by removing water out of the tank’s fungus, parasites, and/or bacteria without harming the underlying concentration. This ensures the general ecosystem inside the aquarium starts to improve due to the newly added aquarium salt.

Aquarium salt is often cited as a great way to help improve a fish’s health inside the tank and can be ideal for helping improve the general environment in which a fish swims.

Experts Say...
Over time, this salt has become the gold standard for fish tank owners and is a go-to option anyone can rely on.

It’s important to note aquarium salt is just a short-term solution and shouldn’t be employed as a long-term addition to any aquarium.

When used excessively, aquarium salt can overwhelm the ecosystem and harm the fish that you are trying to protect.

The premise of aquarium salt is to use as an antibiotic for the fish. This means you treat the fish disease and then get rid of the aquarium salt. Using it regularly is going to endanger your fish because the disease will start to become resistant to the mixture.

This is a key detail to keep in mind when comparing Epsom salt vs aquarium salt.

So, which one should you use when it is time to help your fish?

In general, you are always recommended to go with a specialized aquarium salt for your freshwater tank.

The aquarium salt has more research behind it, the results are often predictable, and you are going to gain more value from the experience as a fish owner. On the other hand, Epsom salt is going to endanger your fish and should never be a go-to option!

Keep things simple and look for the best aquarium salt you can find.

Research shows Epsom salt should only be used in last ditch efforts to help a fish with bloating when aquarium salt doesn’t work.

When you start using the right type of aquarium salt for your freshwater tank, it’s going to start improving your fish’s health and leading to a better ecosystem inside the aquarium.

While some people recommend using Epsom salt for a bloated fish, it’s still something that should be used as a last resort when nothing else works.

Epsom salt is generally unsafe and not something you should be leaning on for your aquarium.

Choose a good aquarium salt for your tank and then use it as instructed. This will go a long way in improving the salinity inside the tank while also keeping your fish healthy.

Aquarium salt has been noted for delivering a noticeable impact on fish dealing with various diseases and the effect can be prominent in a matter of days. This is essential for fish owners wanting a tangible solution to make a difference in their freshwater tank.

The simplicity of aquarium salt and how easy it is to use makes the solution a no-brainer. It offers a way to help reduce a fish’s symptoms and makes the aquarium a more welcoming environment for the fish.

More Refined – When it comes to Epsom salt vs aquarium salt, the idea of going with a more refined salt has to be taken into consideration. Aquarium salt has been around for a long time and is specifically formulated to be used for fish inside tanks. On the other hand, Epsom salt isn’t used for fish tanks and has generally been repurposed for as a solution.

This means using a good aquarium salt solution will yield better results and have a more refined finish to it.

Using Epsom salt won’t do this and that is a risk no fish tank owner wishes to take.

Easier to Use – When choosing the right type of salt for an aquarium, it’s important to look at how easy it is to use. Aquarium salt has been cited as taking no more than a few seconds to set up and put to use inside the tank. In comparison, Epsom salt is a more delicate alternative that has to be methodically used in order for it to not endanger the fish.

This is a risk not worth taking and something most fish owners realize as they start comparing Epsom salt vs aquarium salt.

Instead, it’s better to go with something that is beginner-friendly and will help fish with their underlying diseases.
