Aquarium Maintenance & Water Care

A fish aquarium is a beautiful and tranquil addition to the home. And keeping fish can be a very rewarding hobby. Fish aquariums don't necessarily require as much hands-on care as other pets, either. But aside from feeding your fish the best fish food, the condition of the aquarium water is very important to the well-being of your fish. The best aquarium water conditioners will help ensure that your fish can breathe properly, that the water stays at the right temperature, and that their surrounding ecosystem is balanced and harmonious.Whether you are new to aquarium care or you've been taking care of your tank for years, you should know that water maintenance and conditioning is important. API Stress Coat Aquarium Water Conditioner is best to the use if chlorinated tap water has been added to the tank. This aquarium water conditioner will heal damaged tissue. It's specially formulated to reduce fish stress caused by changes in the aquarium, such as starting a new aquarium, adding or changing water, and adding new fish to your tank. API Proper pH 6.5 Aquarium Water Treatment is a good fish tank pH water treatment sets and stabilizes the water pH levels of your tank at 6.5. It modifies and maintains the pH for several weeks while neutralizing harmful chlorine and toxic heavy metals. It also contains soothing aloe vera and electrolytes to reduce fish stress.Algae is one of the biggest problems in aquariums. Algaecides for water clarity are essential to your fish. Tetra Water Clarifier Freshwater Aquarium Water Conditioner works to clump the particles that cause cloudy conditions in your aquarium. These particles can then be removed during normal fish tank filtration or gravel cleaning. This fish water conditioner is safe for use with fresh and saltwater aquariums. Dr. Tim's Aquatics NP-Active Pearls for Nutrient Control in Aquariums are 100% pure PHA biodegradable pellets designed and tested for aquatic systems. These pearls act as a carbon source for the growth of beneficial bacteria and the natural removal of nitrates and phosphate from water. It's a pure, safe and simple aquarium water treatment for all fish and coral types with no filter. Regular water testing is essential in order to keep your fish healthy and thriving so test the water with a aquarium water test kit especially when setting up a new fish tank. Whether you have a freshwater or marine environment, shop the perfect aquarium and fish water care conditioners here at Chewy.

Frequently Asked Questions about Aquarium Maintenance & Water Care

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.

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.

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.
