Aquarium & Fish Tank Filters

Fish are known to have a tranquil, calming effect on their owners, but not when their fish tank is full of filth. Chewy carries everything you need to keep your aquarium clean and healthy for your finned friend. Water quality determines the health and growth of all your aquarium's inhabitants. The status of your fish tank water is not just an aesthetic concern, but is a fundamental part of managing your fish's health and wellness. Routine water changes used to be a basic aspect of aquarium maintenance. Luckily, aquarium filtration systems reduce time spent deep cleaning fish tanks. A fish tank water filter cleans the water of debris, removes the toxic buildup of ammonia and nitrates, and aerates the water so your pretty fishy can breathe. A filter for fish tank cleaning means you don't have to remove your fish from their habitat every time you need to clean their home. Removing fish from their tank can be traumatizing. Reduce time spent cleaning, and ensure a healthy environment for your finned friend with an aquarium filter. Chewy carries the best aquarium filter products from brands like Penn-Plax, Aqueon and Marineland. The Penn-Plax Cascade Aquarium Canister Filter is an external filter that accommodates a wide range of aquarium filtration needs. Each pump comes with a large filter tray, startup filter media and input/output tubing so you can begin filtering right away. It is suited for both freshwater and saltwater tanks. Reduce the sound your fish filter makes with the Aqueon QuietFlow Fresh & Saltwater Aquarium Filter. It rids your fish tank of debris, toxins, odors, ammonia and nitrates, but its submersed pump is virtually silent. Whether you need a small aquarium filter or a large filter for your fish tank, Chewy has everything you need to keep your fish tank clean and clear.

Frequently Asked Questions about Aquarium & Fish Tank Filters

Do all fish tanks and aquariums need filters?

All fish tanks and aquariums do need filters to clean the water and prevent the buildup of toxic substances. Different aquariums may need different types of aquarium water filters, depending on the fish inside them and whether they are saltwater or freshwater tanks. Chewy carries a wide range of fish tank filters to suit a variety of filtration needs.

What are the best aquarium filters?

The best aquarium filters are those that effectively clean the water by removing chemical impurities and biological toxins in addition to filtering dirt and debris. Choose a filter that is suited to the type of tank you have, as saltwater tanks have different filtration needs than freshwater tanks. Sponge or air-powered fish tank water filters may be adequate for tanks with low filtration needs, but power or hang-on-back filters, canister filters and wet/dry filters can provide more powerful filtration.

What size fish tank filter do I get?

Get a fish tank filter in a size that is suitable for your fish tank. Most fish tank filters list the tank capacity they are suited for, and they also usually list how many gallons of water per minute they can filter.

What are the different types of filters for fish tanks?

The different types of filters for fish tanks are sponge filters, hang on back (HOB) filters, canister filters, trickle or wet/dry filters, box filters and under gravel filters. Filters perform any of three main types of aquarium filtration: biological, mechanical and chemical. Many filters are designed to perform several or all three filtration functions at once, providing your fish with clean and clear water that is free from debris, chemical buildup and harmful toxins.

How often do you need to change aquarium filters?

You need to change aquarium filters at different times depending on which kind you have. Mechanical filters don't need to be replaced until they stop filtering or start falling apart, and replacing them too often can disrupt the balance of the aquarium. The chemical filter should be changed every month, or every two months at the very least. Biological filters allow beneficial bacteria to grow, so replace them only when they start to fail or fall apart. Most aquarium filters, including multi-stage fish tank filters, will usually have instructions for use, maintenance and care, so read all the instructions carefully and follow them well.
