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. The water quality remains stable, and the salt doesn’t cause any harm to my plants, which is important since I have a planted tank. 4. Safe and Easy to Use: This product is easy to measure and dose according to the size of my aquarium. I appreciate the clear instructions on the box, which helps me ensure I’m using the right amount. I also like that it doesn’t affect the pH of the water in a harmful way. I’ve had no issues with the salt causing unwanted spikes in my tank's water parameters. 5. Great Value for the Price: The 67-ounce box is a great value for the price. It lasts a long time, as you only need to use a small amount for each water change or treatment. Given the quality of the product and how much it improves the health of my fish, this is definitely worth the investment. 6. Packaging May Vary, But the Quality Remains the Same: Although the packaging may vary from time to time, the quality of the salt remains consistent. I’ve used this product several times, and every time, it’s been effective and high quality. Final Thoughts: The API Aquarium Salt is a must-have for any freshwater aquarium enthusiast. Whether you’re looking to improve the health of your fish, treat minor injuries, or simply maintain a stable environment, this salt does it all. I highly recommend it to anyone with a freshwater aquarium! 💯 Highly recommended – a great addition to your aquarium care routine for healthy fish!

API is a good brand.
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.

Great product, not the best packaging
I’m a beginner to the world of aquariums, and so when my guppies started to show small signs of illness I searched everywhere for the best way to help their health - all signs pointed to API freshwater aquarium salt. So far it seems to be working great. My fish are happy and seemingly healthy, my only problem is that the salt spilled inside of the box it came in.

It’s Salt. And It’s Glorious.
It’s salt. For fish. What more can I say? My fish aren’t throwing a party or anything, but they do look mildly impressed. Clears things up, keeps them healthy, and they haven’t staged a tiny underwater protest since I started using it. So that’s a win. If your fish are being dramatic, toss in a little of this and suddenly they’re gliding around like they’ve got a spa day booked. 10/10 — it’s salty and it works.
