• Mechanical, chemical, and biological filtration — addresses different stages of aquarium water filtration.
• Includes AquaClear Foam, Activated Carbon Filter, and AquaClear BioMax — supplies three types of filter media to get started.
• Up to 7 times the filtration volume of comparable filters — provides a larger volume for water to pass through filter media.
• Up to 6 times more media volume — allows increased water-to-media contact.
• Maximum output of 150 U.S. Gal./h (568 L/h) — provides a stated flow rate for selecting a filter.

Keeping aquarium water clear calls for filtration that handles mechanical, chemical, and biological processes while circulating water back into the tank. The AquaClear AC30 is designed for aquariums in its stated size range, including freshwater fish and live aquarium plants. Its adjustable flow and included media make it suitable for setups where water movement and filtration need to be tailored to the tank.

What aquarium size is the AquaClear AC30 designed for?

The Fluval AquaClear AC30 is designed for aquariums holding 10–30 US gallons (38 to 114 L). Its maximum output is 150 U.S. Gal./h (568 L/h), giving you a concrete flow specification when choosing a filter for a tank within that capacity range.

It hangs on the aquarium and is made to fit securely on most tanks in the 10–30 gallon range. The adjustable flow control lets you change the water flow according to the aquarium’s needs rather than relying on a fixed setting.

• Hang-on filter format for aquarium use.
• Flow can be adjusted using the patented control feature.

What filtration does it provide, and what media is included?

The Fluval AquaClear AC30 provides mechanical, chemical, and biological filtration through its multi-stage system. The included AquaClear Foam, Activated Carbon Filter, and AquaClear BioMax form the supplied media set.

Its filtration volume is up to 7 times larger than that of comparable filters, and its design allows up to 6 times more media volume. A media basket keeps water from bypassing the media, while extended contact between water and filter media supports the filtration process. The system also preserves beneficial bacteria, which contributes to a stable aquarium environment.

• AquaClear Foam is included as part of the filter media set.
• Activated Carbon Filter and AquaClear BioMax are also included.
• Zeo-Carb and Ammonia Remover are additional media designed for the AquaClear 30.

How does the filter return water to the aquarium?

The Fluval AquaClear AC30 returns filtered water through a waterfall-style outlet that gently breaks the water surface and promotes oxygenation. Its energy-saving pump is designed to reduce operating costs, and the filter is designed for quiet operation.

Cycle Guard supports continuous biological filtration, helping maintain a stable environment for aquarium inhabitants. The filtration system is also designed to remove toxins, odors, and discoloration from aquarium water. These features support use in freshwater and saltwater aquariums; the product description also identifies freshwater fish and live aquarium plants as suitable inhabitants.

• The waterfall return gently moves the water surface.
• Flow control lets you tailor output to aquarium needs.

How do you install and maintain the AquaClear AC30?

The Fluval AquaClear AC30 is designed for quick installation and straightforward maintenance. Clean the filter every 2 weeks to support its operation and help keep aquarium water clear.

Its media basket holds the filter media in place within the filtration path, and the included media can be accessed as part of routine maintenance. The range of AquaClear media also includes options designed specifically for this filter, including Zeo-Carb and Ammonia Remover.

• Routine cleaning interval: every 2 weeks.
• Compatible AquaClear media options include Zeo-Carb and Ammonia Remover.

The AquaClear AC30 suits aquarium keepers with a 10–30 US gallon tank who want adjustable flow and mechanical, chemical, and biological filtration in a hang-on format. Its included foam, activated carbon, and BioMax media provide three filtration materials, while the waterfall return and flow control let you tailor how water moves through the aquarium.
