## Description

A lack of electrolytes in aquarium freshwater may cause serious health problems for freshwater fish. API AQUARIUM SALT supplies electrolytes to improve fish respiration. Made from evaporated sea water and containing natural active ingredients such as a natural fish tonic, API AQUARIUM SALT promotes the overall health of your fish by improving their gill function and reducing stress in a freshwater aquarium. This all-natural salt provides the essential electrolytes fish need for the uptake of oxygen and release of carbon dioxide and ammonia through the gills. API AQUARIUM SALT should only be added to reduce stress during new freshwater aquarium setup and water changes or to promote disease recovery when solving specific fish health issues. Use API AQUARIUM SALT when setting up a new freshwater aquarium, when changing water or treating disease. Make sure to take extra care when using salt with live plants, as some plants may be sensitive. With API Aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For over 50 years, API has been creating innovative, research-driven solutions that make it easier to care for your fish and aquarium. API Aquarium Treatment Supplies are designed to work in conjunction with each other to provide best results to control algae, promote healthy bacterial growth and help control and cure fish diseases and conditions such as ich and fin rot. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. With API, you can spend more time admiring your fish, and less time scrubbing your tank. Make sure to use all products as directed in order to ensure the best results.

Review: Essential for Freshwater Aquariums – Must-Have for Healthy Fish! - I’ve been using the API Aquarium Salt for my freshwater aquarium for quite some time now, and I’m thoroughly impressed with the results. Here’s why I’m giving this product a full 5-star review: 1. Promotes Fish Health: This aquarium salt is great for promoting the overall health of my fish. I’ve noticed an improvement in the vitality and color of my fish, especially when used during water changes or to help treat minor illnesses. The salt provides essential electrolytes that help maintain osmotic balance and promote a healthy immune system for the fish. 2. Works as a Healing Aid: I’ve used this salt to treat minor ailments in my fish, such as stress or injuries. It’s been especially effective in helping fish recover from small cuts or scrapes. I follow the instructions, and it seems to work wonders in speeding up recovery and reducing stress levels in my tank. It’s also helpful when acclimating new fish to the tank environment. 3. Perfect for Freshwater Aquariums: I’ve used other salt products in the past, but this one stands out for its quality and effectiveness specifically for freshwater aquariums. It dissolves easily and doesn’t cloud the water, which is a huge plus.

### ⭐⭐⭐⭐⭐ API is a good brand.
*by N***K on January 6, 2026*

Qualities seems to be good. It seems to be effective. No bad or odd smells. The only issue I had was the cardboard container that the salt is in was slightly opened in the corner upper edge + just looked like the glue didn't seal properly at manufacturer, there was some salt spilled in the shipping box, but I was able to save it.
