Common water change mistakes that can stress bettas or disrupt the tank.
Common betta water change mistakes include using untreated tap water, changing too much at once, temperature shock, replacing all filter media, and ignoring water tests.
Always condition tap water before adding it to the aquarium.
New water should be close to the tank temperature. Sudden changes can stress fish.
Do not replace all filter media or scrub every surface at once. Beneficial bacteria are part of the tanks stability.
