2. Fluval Aquarium Power Filter – Best Value

The Fluval Aquarium Power Filter is the best aquarium filter for large tanks for the money due to its functionality and budget-friendly price. This hang-on back filter comes in three sizes for tanks from 30–70 gallons.

It uses 5-stage filtration to ensure your water is being fully cleaned through its mechanical, biological, and chemical filter media. It uses a patented refiltration system that recirculates the water through the filter multiple times before returning it to the tank, ensuring a thorough clean.

It’s easy to set up and clean, and it features a pop-up indicator that lets you know when it is time to clean your filter media. The draw tab makes it easy to remove the filter media basket for cleaning and maintenance. It includes all the filter media you need to get started.

This filter is louder than some of the other options, and some people report it becoming clogged easily.

3. Eheim Classic 600 Aquarium Filter – Premium Choice

The Eheim Classic 600 External Aquarium Canister Filter is the premium choice for filters for your large aquarium. This canister filter does only offer mechanical and biological filtration and is one of the more expensive options. However, it includes all the needed filter media, and there is a built-in permo-elastic silicone ring in the pump head to ensure it doesn’t leak.

It includes thorough instructions and is easy to set up and maintain. This filter is compact for its power level, measuring only 15.7 inches tall with a diameter of 8.07 inches. It can be used for tanks up to 159 gallons, making it the ideal addition to your large tank setup.

Understanding the intricacies of water filtration can be tricky, so if you're a new or even experienced goldfish owner who wants a bit more detailed information on it, we recommend that you check out Amazon for the best-selling book, The Truth About Goldfish.

The Marineland Bio-Wheel Penguin Aquarium Power Filter is available in four sizes for tanks up to 75 gallons, and it is one of the more budget-friendly filters for large tanks. This hang-on back filter uses 3-stage filtration, including a patented Bio-Wheel that provides maximum surface area for beneficial bacteria growth.

The Bio-Wheel includes vented covers that reduce noise, although some people still report noise from the Bio-Wheel turning. Some maintenance and cleaning are specific to the Bio-Wheel, so it’s important to read through those instructions to keep this filter working at its maximum potential for the longest period of time.

It’s made for tanks up to 90 gallons, and it has a built-in adjustable flow control, ensuring your Bio-Wheel has maximum contact with the water for proper cleaning and your water flow is appropriate for what your tank needs. It includes the filter media you need to get started, as well as an extra filter cartridge slot, although it doesn’t include an extra cartridge.

This may be a somewhat noisy filter, even with built-in noise dampeners, due to the Bio-Wheel. You’ll need to read up on and maintain the Bio-Wheel cleaning and maintenance schedule properly to ensure it continues to work correctly.

Buyer’s Guide: Choosing the Best Aquarium Filter for Your Large Tank

When it comes to selecting the best aquarium filter for your needs, the first thing to do is make sure you are aware of the size of your tank. An under-filtered tank can lead to problems with water quality, but you aren’t going to over-filter your tank unless you keep very sensitive plants and animals. You’ll also need to take a serious look at your willingness to perform tank and filter maintenance. If it’s something that often gets put on the back burner, then you may need to invest in a filtration system that is larger than the size of your tank.

You should also consider what types of filtration are important to you. Some people are content not to use chemical filtration, but some people don’t like dealing with unpleasant smells from their aquarium that chemical filtration could remove. Some types of filters have added benefits, like UV sterilization or water polishing, which aren’t essential to your tank but can be very helpful.

Take into account what type of filter you’re in the market for. Many people prefer canister filters due to their functionality, but they tend to be more expensive and take up more room than other types of filters. Hang-on back filters need space on at least one side of the tank to hang from, while internal filters may not be suitable for all tank setups.
