Aquarium & Fish Tank Salt

A little salt can go a long way—fish aquarium salt helps support a healthy tank environment and happier fish! Used to promote gill function, reduce stress, and aid in disease prevention, aquarium salt is a great tool for freshwater and brackish tanks when used correctly. Whether you're maintaining water quality or treating specific health concerns, the right dose of aquarium salt can benefit many fish species. Some key considerations when selecting fish aquarium salt includes:

  • Type: Ensure you're using aquarium-specific salt, not table or marine salt
  • Compatibility: Some freshwater fish tolerate salt well, while others require a strictly salt-free environment
  • Dosage: Follow species-specific guidelines, as too much salt can harm sensitive fish
  • Usage: Aquarium salt can be used for routine maintenance, stress reduction, or disease treatment
  • Dissolvability: Fine-grain salts dissolve more quickly, making them easier to use in tank treatments

Using fish aquarium salt correctly can help promote fish health and improve overall water quality. With Chewy.com's Autoship service, you can have your aquarium salt delivered on a schedule that works for you, so your tank is always stocked with what it needs.

Frequently Asked Questions about Aquarium & Fish Tank Salt

What is fish aquarium salt?

Fish aquarium salt is a specially formulated salt designed for freshwater aquariums. It helps promote gill function, reduce stress, and support fish health while maintaining water quality.

Is aquarium salt safe for fish?

When used properly, aquarium salt is safe for many freshwater fish. However, some species, such as scaleless fish, may be more sensitive to salt. Always check your fish's specific needs before adding salt to the tank.

How often should you put aquarium salt in a fish tank?

Aquarium salt should only be added when performing water changes, as it does not evaporate. The frequency depends on the purpose of use. Some tanks benefit from regular low doses, while others may only need salt for treating fish health issues.

What fish cannot tolerate aquarium salt?

Some fish, such as tetras, corydoras catfish, and certain scaleless species, are highly sensitive to salt and may experience stress or health issues if exposed to it. Always research your fish's tolerance before adding salt to the tank.

What happens if you put too much aquarium salt in your tank?

Too much aquarium salt can cause dehydration, stress, or even death in salt-sensitive fish. It's important to measure carefully and follow recommended dosages to avoid harming your aquatic pets.
