    • Betta’s review
Size: 1 gallon (Pack of 1)
Okay yes it works well. Might even have everything my betta needs. But also using distilled water, and 3 drops of of crystal pro aquatics water balancer was much more money efficient. Both keep betta alive, I might stick to my distilled water with the 3 drops that cost no more then 10$ for 5 gallon tank. Or use 4 of these big expensive betta water that cost more then 50$… great product though. ... show more

    • Betta Water, it does what it needs to do
Size: 1 gallon (Pack of 1)
If you love bettas but are impatient to allow 6-8 weeks to accumulate for a new fish tank Betta Water is for you. It eliminates the need to cycle the tank and allows instant addition of a fish to a new tank. Sure, it is not needed. But if your budget allows for it, go for it. You do not need to keep buying it for every water change. The price for it is definitely outrageous. But to get the betta you fell in love with and was able to bring it home out of that horrid plastic cup it's worth the initial investment. The nitrogen cycle is very important for a new tank, do not forget this if you're getting any pet fish. This does help for fish lovers who are impatient. It does work but it's at a cost. ... show more

    • Our Betta fish have always loved Activ Beta
Size: 1 gallon (Pack of 1)
Review Image by Paul T Nawrocki
Makes our Berra fish “Cooper” more lively, playful and inquisitive. We always buy Activ Beta. I don’t know why price varies as often as it does though. Is this a supply and demand issue? I don’t but as much (obviously) when the price goes up as much S it was in September. It is more reasonable now but the smaller bottles are still twice what they once were. Will they come down in price eventually? Iee have purchased Activ Beta for over three years now at an average of three gallons per month. ... show more

    • The best!!
Size: 1 gallon (Pack of 1)
I couldn’t balance my own tap water, when we got our beta fish, for the life of me. Luckily, I got this water delivered by Amazon, ASAP, and now, our little fish friend has a great tank. The water comes, ready to use. You just pour it into your tank, and you’re ready to go. It appears clear, so you won’t have foggy water. The container it comes in isn’t the most durable container, but it holds up just fine. The water is balanced perfectly for your fish, to keep them as healthy as possible and looking their very best. This water works great, and will make your tank water the color of water- crystal clear! ... show more
