PausitoRoutine BuilderHow often should you change your aquarium water?
Change part of the water in your aquarium every 2 weeks, about 30 percent.
Without regular water changes, waste products such as nitrate build up, which stresses your fish and makes them ill over time. If you have a small aquarium with lots of fish, change water more often or a larger portion. Use water at the same temperature, treated with a conditioner.
- Use a gravel cleaner to siphon off some of the dirt on the bottom while draining
- Change about 30 percent of the water
- Add fresh water at the same temperature, treated with conditioner
- Afterwards, briefly check how the fish are behaving
