Aquarium salt is a type of salt used in freshwater aquariums to support the health of fish and improve water quality. It's different from table salt or sea salt in that it does not contain additives like iodine or anti-caking agents, which can be harmful to aquatic life. Here’s a detailed look at aquarium salt:

• Osmotic Regulation: Aquarium salt helps fish maintain proper osmotic balance. In freshwater aquariums, fish often face challenges in maintaining their internal salt concentrations due to the low salt levels in their environment. Salt can help fish regulate their bodily fluids and reduce stress.
• Health Support: It can aid in the treatment and prevention of certain diseases and parasites. For example, aquarium salt is often used to help treat ich (Ichthyophthirius multifiliis), a common parasitic infection.
• Gill Health: Salt can also support gill function, making it easier for fish to breathe and reducing the risk of gill-related issues.

• Dosage: Follow the manufacturer’s instructions for dosage, as too much salt can be harmful. Typically, it’s added at a rate of about 1 teaspoon per gallon of water, but this can vary depending on the specific needs of your aquarium.
• Dissolving Salt: Dissolve the salt in a separate container of aquarium water before adding it to the tank. This helps ensure even distribution and prevents direct contact with fish.

Partial Water Changes: When performing water changes, you may need to re-add salt to maintain the appropriate concentration in the tank.

• Not for All Fish: Some freshwater species, especially those from soft-water environments or those sensitive to salt, may not tolerate aquarium salt well. Always research the specific needs of your fish before adding salt to the tank.
• Temporary Use: Aquarium salt is typically used as a temporary treatment rather than a permanent addition. It’s often used during illness or stress but should be removed when it’s no longer needed.

Compatibility with Other Treatments: Be cautious when using aquarium salt alongside other treatments or medications, as interactions may occur. Always read labels and consult with a knowledgeable aquarium professional if in doubt.

• Marine Salt: For saltwater aquariums, marine salt (or reef salt) is used, which contains a mix of salts and minerals specifically designed to replicate seawater conditions. This is different from aquarium salt used in freshwater tanks.
