An aquarium filter should be able to process all of the water in the tank three to five times an hour. For example, the filter in a 20-gallon tank would need to push through at least 60 gallons of water each hour. Follow the manufacturer’s instructions for choosing and setting up the filter.
PetSmart offers free aquarium water testing. Bring in a sample and we can test its quality within minutes.
General aquarium health and environmental guidelines
Fish and aquatic animals can transmit zoonotic disease to humans. Wash your hands with soap and water before and after interacting with your aquarium. Children, pregnant women, elderly people and those with immune-system problems should take extra care.
Keep fish away from food and areas where food is prepared.
Never release fish into the wild.
