API Aquarium Salt
API® AQUARIUM SALT is made from evaporated sea salt and is a must-have for your aquarium! AQUARIUM SALT promotes fish health by improving gill function, making it easier for fish to breathe. It also provides essential electrolytes that fish need to reach peak coloration and vitality. These electrolytes may be lost each time you perform a partial water change, and will need to be replenished.
Use API AQUARIUM SALT in freshwater aquarium tanks when starting a new aquarium, and any time you perform a water change. Care should be taken when using salt in aquariums with live plants, as some plants may be sensitive.

I’ve used this salt for three months now and my fish have shown brighter colors. The gill function seems better too. I added it after each water change and noticed a difference in their activity. My tank feels more balanced.
Jason Chapman –
Works well for my community tank. My fish are more active and the water seems to stabilize better. I did notice one plant started to yellow, so I stopped using it in that section. Still, overall a good product.
Abigail Gill –
Great for new tank setups. The salt helped my fish adjust faster after the initial water change. I’ve used it consistently and haven’t had any issues with my fish’s health or coloration.

It’s effective, but I had to reduce the amount because my anubias showed signs of stress. I now only use it in fish-only tanks. Still useful for maintaining electrolyte balance.

My betta has been more vibrant since I started using this salt. I follow the dosage carefully and it’s become a regular part of my maintenance routine.
