How much maintenance do fish tanks require?

Fish tanks require regular maintenance to keep the aquarium environment safe. Routine maintenance tasks include daily checks and fish feedings, regular water temperature and equipment checks, and light aquarium cleaning every week or so. You will also need to thoroughly clean your tank periodically and replace filter media as needed. Regular water testing and water replacement are also essential for fish tank maintenance. Chewy has an excellent selection of aquarium maintenance and water care supplies to help you get the job done right.

What kind of water care do aquariums need?

Aquariums need various kinds of water care to support healthy environmental conditions for fish. You will have to replace the water in your tank regularly, so you'll need a water conditioner to remove chlorine from your tap water and aquarium salt if you have a saltwater tank. Water testing is another important part of aquarium water care and needs to be done monthly or more frequently if your tank is having issues. Other water care tasks include correcting pH, algae, ammonia or phosphate levels if a water testing kit tells you they are out of balance. Biological aids, including water filter media, as well as water additives are essential water care tools that will help you keep your water healthy for your fish.

How often should you change the water in a fish tank?

You should change some of the water in your fish tank every week, but avoid changing all of it at once. Replacing too much water at once can upset the balance of your tank and stress your fish. A good practice is to change 10% to 15% of your water weekly. Be sure to condition your tap water with a water conditioner and test the water regularly to make sure it is healthy.

What supplies do I need to maintain my aquarium?

The supplies you need to maintain your aquarium include water test kits, water conditioners, aquarium water treatments, and filter replacement media. You may also need plant food if your aquarium has live plants and salt and mineral supplements for saltwater tanks. Water additives that contain beneficial bacteria may also be helpful. You can use these when setting up new tanks, after big water changes and whenever adding new fish.
