You should clean your African dwarf frog tank once a week. African dwarf frogs may not produce a lot of waste, but they are extremely sensitive to water quality. These delicate frogs need a clean and well-maintained tank to thrive.
Ideally, you should clean the tank and change around 10% of the water once a week. You should also check the ammonia, nitrite, and nitrate levels once or twice a week.
Additionally, make sure to maintain and clean their tank’s filter at least once a month.
