Great product!!
Water quality is amazing super clear after putting this product in my fish tank, the product spreads fast and works immediately, it does the job, after the pour I waited 10 min to put the fish in and no shock was seen nor any stress in the fish

Works fast and no Problems
Did a partial water change, put in the proper amount of additive, and added water. All the fish were fine after the water change. I have been using Fluval brand of water conditioner for my Betta fish tanks and 20-gallon hex for about a year and a half and have had no issues! Also, it is always a really good price and you get a lot of product! Also, it removes chloramine, which not all conditioners do. The only thing that I can say about this that is negative is the measuring cup that comes with it does not measure for anything smaller than 10 gallons. So for my 3-gallon tank, I have to measure for myself using some estimation on the cap. Iâve never had an issue with this, but it is just a tiny bit less convenient. Used to buy it at my fish store, but as usual, Amazon has the best price and it’s delivered fast to your door!

My go-to solution for treating aquarium water
Fluval water conditioner is an absolutely great solution to removing chlorine from your aquarium water. I love the dosing cup, early in adopting the hobby I tried a few products with squeeze bottle drip tops and hated them. The 16.9 oz (500 ml) bottle is the perfect size for holding plenty of product and still being easy to accurately dose. I currently have 3 active tanks, 2 tropical and a goldfish, that I use this in. I’ve never had any issues with cloudiness or fish problems related to the conditioner, my fish and crustaceans seem to take to it quite well.Overall, I have nothing but good things to say about the water conditioner. Everything Fluval that I have tried has exceeded expectations. In my experience, their reputation for quality aquarium products has been well earned.

Works…
Works as described. However, if you have a lot of large tanks, it’s not very cost effective.

Good name, does what its supposed to do… Would only change one tiny thing for perfection.
Seems to do what it’s supposed to and a good name. The only thing I’d change is, there is one brand that has directions for dose (3drops) for each gallon of water– Since I refill my tank using gallon containers, that’s very handy– I just treat the water before I add it to the tank. This has measurements for larger quantities…. So you have to estimate how much water you’ll be putting in, measure it it, then add a bit to each gallon (I have glass cats and they’re really sensitive to stuff in the water — so I like the water treated before I put it in, and not too little and not too much!). Which just doesn’t seem too accurate and is a pain. I suppose I could sit down and figure it out mathmatically, but wouldve been really nice to just have a top capable of drops when not squeezed much, and dose written on the label. But that’s personal preference– the product is good!

I am switching to this after using Seachem Prime. Prime is a great products but I don’t like it’s smell. This one does the same and doesn’t smell. I haven’t seen any issues when I switched so quite happy with it. Recommended.

Von der guten Qualität unseres Fluval-Aquarium bereits überzeugt, habe ich den Wasseraufbereiter des Herstellers probiert. Das positive Bild hat sich fortgesetzt. Anders als bei anderen Markenherstellern ist hier die Anleitung nicht so klein gedruckt, dass man diese gar nicht mehr lesen kann. Die Dosierung ist problemlos und das Wasser ist klar. Bei anderen Produkten ist das bearbeitete Wasser immer mit einem Grünstich versehen gewesen, was beim Einfüllen ins Aquarium aufgefallen ist.
