To maintain a saltwater aquarium, you’ll need to have routines in place. New saltwater aquariums can take time to establish colonies of healthy bacteria that break down ammonia into appropriate forms. You should perform weekly water changes for the first few months and test your saltwater frequently to catch problems before they occur. You should also regularly clean salt from equipment and remove algae from décor.
Every day water maintenance tasks can include checking salinity, topping off water levels, checking the water quality, regulating water temperature and feeding your pet fish. Every week you should change your water, maintain filtration and scrub algae. To learn more about caring for saltwater marine fish, check out our saltwater pet fish guide.
