Beneficial bacteria in products like additives or sand is a good way to provide denitrifying bacteria to turbo charge your nitrogen cycle and now there is a way to do this during a water change. Activ-Betta Bio-Activ Live Aqueous Solution Betta Water is a water that contains denitrifying bacteria and trace elements to provide a strong boost for your betta fish.
According to the company, it delivers “the only complete, instantly balanced and safe environment for your little finned friend.” The water contains no chlorines or chloramines and cycles instantly so there’s no waiting–just change the water and add fish.
While this is geared towards bettas that are commonly sold with smaller tanks with little to no filters, this could also be a handy way to skip the tapwater and chlorine and chloramine removers and go straight for the bottle of water. For optimum results, Activ-Betta recommends changing your betta’s water every 8-11 days.
The water comes in 1 liter bottles that retail for just under $4.
