  • Great water for my betta!
Size: 64 oz
I’ve been using this Betta Water for a while now, and it’s super convenient. No need to add any conditioner—just pour it in, and it’s ready to go. My betta seems healthy and active, and the water stays clear. The 64-ounce bottle lasts a good amount of time, too. Definitely recommend for betta owners who want something easy and reliable ... show more

  • Magical clean water
Size: 64 oz
I swear this stuff does not get nasty. I do feel like it is expensive for water, but this stuff never gets dirty. It lasts a long time. It is a full gallon and I normally have to buy a few, but it lasts forever.

  • Betta Water
Size: 64 oz
Easy to use. My Betta is really mellow and not stressed. Very playful, all of this shows a well balanced mix. If that makes sense to the ones who read my review ? All in all I will continue buying this product.

  • Betta Fish is still kicking
Size: 64 oz
Why did you pick this product vs others?: Product has good reviews and my betta has died after water changes. Expensive for the size though.

  • Fish lived!
Size: 64 oz
This has been a life saver as we learned after buying our son a Beta that our water is too hard for fish! They came with the lids intact so no leaking and had a special leak guard on them. Our beta was unaffected by the transition which is what we were hoping for! They were slightly more expensive than beta water at Walmart.

  • Fish isn't swimming well
Size: 64 oz
I'm not sure about this water. I have a betta fish he was swimming fine until I used this water. Its been about a week now. He stays at the bottom of his bowl with his head straight up. The pet store advise me to bring a sample of water to test the ph. They said the ph was fine, but he still isn't swimming well. He's having a hard time swimming to the top. I won't use this water again. I was using a different water from the pet store befoee and he was doing well with that. This water may be too strong. ... show more
