This was a great find
This, keeps my goldfish alive. 9 tablespoonsful in my 180 L tank each time does the trick no more red tummies or fins. This was a brilliant find

Improved water quality
Thought I'd give this a try, it certainly seems to improve the water quality and good quality water means happier fish.

I love this🥰🥰🥰
I really like it because before I had to change my fish tank water once a week, now I only change it every two weeks. It saves me a lot of time, and the water is as clear as if I just changed it every day🥰

Early day but so far , so good !
Had to isolate one of my small pond koi yesterday after noticing it just doesn’t seem to come up to the surface for food , I just never seem to see it & I’ve only had it for approx 4 weeks . On closer inspection I found it hiding behind plants & my much larger Koi ganging up on it so I immediately removed & isolated it in a tank with plenty of air stones , Did some research & the symptoms pointed to “Fungus “ . I ordered this salt Last night , it arrived this morning so I immediately gave the Little Koi a 10 minute salt bath before popping it back in isolation . It’s only early days But the Koi has definitely livened up & is attempting to swim around the tank , this is right after the fish had spent the entire time laid on the bottom of the tank since yesterday , not eating , gasping & totally lethargic . If this is the result from just one use I’m very impressed . Will be treating again tomorrow. ( 24 hours apart as instructed) Product arrived with slight leakage but nothing too bad , you get plenty of product for the price too so it will last a while . I’d definitely recommend it .

Great product but poor quality control during shipping
Great product, I've used it many times before and it works great to improve fish colours and health. As I had run out I ordered some more aquarium salts but I am extremely disappointed to open my package and see that there is a tear in the box and a lot of salt has spilled out into the packaging.

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
