The Ultimate Buyer’s Guide For Choosing The Best Aquarium Filter

Best Aquarium Filter reviewsAn aquarium filter aerates the water inside an aquarium by removing unwanted particles and chemicals to make a clean habitat for the fishes. Waste products include animal waste, decaying components, and uneaten food, which can generate nitrates and ammonia in the water. These, not only spoil the ecosystem of the aquarium but are also harmful to the fishes.

Using aquarium filters makes the water clean and rich in oxygen for the fishes to breathe and thrive. There are many options available online, but some of the best ones are available on Amazon with customer ratings and reviews, which helps to facilitate your decision. Users have shared both good and not-so-good reviews based on their usage and experiences.

Types of filtration processes:

  • Biological Filtration

    is mostly done by sponge and under-gravel filters, which helps beneficial bacteria to thrive in the aquarium, which converts ammonia and nitrate to less harmful products.

  • Mechanical Filtration

    uses a synthetic material with foam and floss, which sieves to capture the floating solid particles and removes them from the water.

  • Chemical Filtration

    uses activated carbons and resin, which attracts and pulls the chemical wastes to the surface by the process of adsorption, which can be easily removed from there.

 Types of aquarium filters:

types of filters

  • External Filters

    like Hang-on-the-back, Canister, and Wet/Dry Filters.

  • Internal Filters

    include Corner Box and Sponge Filters, and Under-Gravel Filter Trays.

 Factors for deciding on the right aquarium filter

  • Size of the aquarium:

    The volume of the tank is an important factor. Larger tanks are best cleaned with external filters, and they may require more than one filter.

  • Cleaning frequency:

    People, who don’t want to clean their tanks too often can opt for an external filter, while internal ones need more frequent maintenance.

  • Budget:

    The price is also a major factor, considering performance and maintenance. External filters like Canister Filters have a high level of performance, but they are expensive. Internal filters are cheaper, but they are not suitable for larger tanks.

  • Other factors:

    Include the type of pets like fishes or turtle; or the number of pets inside the tank. One more factor can be to whom filters are accessible and where they need to be fitted.

  • It has AquaClear Foam, Activated Carbon and BioMax and Cycle Guard for continuous biological filtration and superior water quality
  • It comes with a 2-year warranty


It is a unique aquarium filter with patented re-filtration in the Hang-on filter category. It draws water from the aquarium via a U-tube and sends out the impeller assembly. The water goes through filter inserts, which removes the debris and waste products. The flow control reduces the flow up to 50% without hampering the functioning. When the flow rate reduces, around 50% of the water inside is processed multiple times. Hence, it gives a clearer and healthier water. It has an exclusive Cycle Guard System, which includes the BioMax Ceramic media insert. This helps to ensure that all filtration requirements are fulfilled by providing three distinct filter media.

The AquaClear provides optimal mechanical and chemical filtering. Since only one of the three filtering components is changed at a time, it ensures that the beneficial bacteria are kept intact for a better process, unlike the cartridge system, where replacing the cartridge means getting rid of the beneficial bacteria as well, which again forms after weeks.


The filter needs to be cleaned every two weeks. The remaining water in the filter case needs to be thrown out, after removing the case. The debris from the case and impeller assembly needs to be cleaned with lukewarm water. The U-shaped intake tube and the extensions need to be cleaned with filter stem brush to get rid of the deposits. Then, the filter needs to be re-assembled and fitted with requisite media. Finally, it needs to be fitted with the tip kept a little forward. Then, the aquarium water is poured into it. The media needs to be replaced as per schedule.

  1. Filter Cover
  2. Filter Case
