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.

So far, I think the best purchase I have made in regards to my Betta beauty. I have struggled with fin rot with my Bettas due to them biting their own tails and the introduction of fish likely causing bacteria to set in. I tried everything, I made sure my cleaning regime was perfect, had good heat, feeding and changed decorations to prevent boredom but it didn't help. My first boy got tail rot and I treated it with melafix as was recommended by the petshop worker, it worked for my mum but my boy died. My second boy is truly a unique beauty who came with a ripped tail. Slowly, this turned to mild finrot that resulted in dissolving, drooping fins and black discolouration as is common. I tried this salt with the recommended doses and after 1 day my boy has his tail fanned out all the time. He is looking happier already! My advice: dissolve salt in a cup with aquarium water before introducing it to the actual aquarium water with fish in it. It will burn them otherwise! -be sure to do 100% water changes once a day if you are treating them for a disease like finrot by dosing the water with salt. Do not exceed using the salt for more than 10 days in a row as treatment, it will start to harm the fish. Compounding the salt will only do harm, water changes are a must ! Again, I highly recommend this product!!! I will update as his treatment continues with aquarium salt. And shipping was so fast! The photo shows him, albietly blurry, all fanned up after one day of treatment with the API Aquarium Salt. His tail has lost half of its length to finrot but he is looking happy again.

Voilà un super produit qui est un médicament et qui doit être utilisé intelligemment et avec précaution ! Vous ne prenez pas un doliprane quand vous avez une artère ouverte (enfin j'espère) Je ne sais pas pourquoi ce produit n'est pas plus utilisé ou plus recommandé en France pour moi c'est un must have pour toutes les personnes ayant des poissons Si votre poisson est malade renseigner vous bien et agissez rapidement. C'est pourquoi je vous recommande d'acheter ce produit en prévention les poissons tombant malade souvent un samedi soir quand tout est fermé ! Il est quasiment impossible d'avoir tout les antibio plus cibler nageoire infecter point blanc etc ici on a un bon compromis qui peut aider/temporiser en attendant de pouvoir acheter le médicament spécifique nécessaire Je pense qu'il faut toujours utiliser ce produit en bac hôpital ainsi que la plupart des antibio sinon vous aller flinguer la faune et la flore bénéfique à votre aquarium et au final peut être faire plus de mal que de bien Renseigner vous et agissez intelligemment Ce produit vos ces 5 étoiles sans problemes Désolé si il n'a pas sauver votre poissons au si vous l'avez mal utiliser Dernier petit conseil lors de l'utilisation des antibio ou bac hôpital attention au surdosage vraiment vraiment je pense que sous doser c'est mieux Et si le pire arrive ne vous en voulez pas trop continuer d'apprendre et de vous faire plaisir avec l'aquario c'est un hobbi vraiment plus difficile qu'on vous le fait croire et frustrant souvent mais magnifique et plein de bon moment Un entretien soutenus de laquarium et l'observatin de vos poissons ainsi que les recherches sont primordial pour la survie de vos protéger Bonne journée a tous
