Questions & Answers

4 Customer Questions

Is this safe for African Dwarf Frogs?

Is this safe for shrimp and snails ?

Answer by Chewy • Apr 23, 2021
Aqueon PURE is safe to use with shrimp and snails and cannot be overdosed. PURE is live beneficial bacteria and enzymes and gets used as needed. These bacteria live on the surfaces of the aquarium such as rocks, plants, décor, and filter media.

Can this be used to cycle a tank? If so, how long will it take to cycle the tank with this supplement?

Answer by Chewy • Jul 26, 2022
It is recommended to add two PURE per 10 gallons of tank water when starting a new aquarium. Add one PURE per 10 gallons of tank water each week. PURE disappears to the eye when added directly to the aquarium and works most effectively when introduced to a filtered tank system. While it does not dissolve completely, the small PURE left behind will go unnoticed and be removed during water changes.

Is this safe for a beta?

Answer by Chewy • Aug 26, 2022
This is suitable for tropical freshwater fish such as Betta.

Life saving!

These literally saved my fish's life! My cycle crashed and all my parameters were awful! I put these little balls in and within days, my cycle was saved. I use these with every water change and I've never had a problem since! They do not completely dissolve, so you can just scoop out some older ones if that bothers you. They cannot be overdosed either so that takes a lot of stress out of dosing.

Good Stuff

I've used these for stabilizing a freshwater aquarium. I like that the aquarium water only uses what it needs.

We bought our first pack of these from a local pet store to try them out first and these work wonderfully. I test my current 3g tank parameters every day and can see the difference before we started using them. I definitely recommend! The water even stays clear like it should unless I of course drop a snello in and that will end up changing the color of the water for about a day or two. (I have a Female Veiltail Betta and a Magenta Mystery Snail.)- Photo of my betta in her tank using these.
