Bettafanatic
Aquarium Advice Addict
Was just wondering this since I'm cleaning out one of my tanks. My betta died and I'm preparing for a new one. If I do a 100% water change, will all the beneficial bacteria die because of new water?

Then decontaminate the tank. A perfectly healthy Betta isn't active the night before then dies the next morning of natural causes; so there is obviously a problem. I would personally start a new cycle after THOROUGHLY cleaning out the filter, decor, gravel, the tank itself. After everything is clean, if you have an existing, established tank seed the Betta tank with established materials then add an ammonia source etc.
Is this Betta tank 5 Gallons?
