## Summary description

Fluval AC20 is a cascade (hang-on) power filter designed for aquariums with 18–76 L capacity. It provides mechanical, chemical and biological filtration with multi-stage media, adjustable flow and easy access cartridges for maintenance. Ideal for small freshwater or planted tanks to maintain water clarity and healthy conditions for fish and invertebrates.

## Long description

Fluval AC20 Power Filter cascade hang-on filter is designed for aquariums with a capacity of 18–76 L. The unit provides three-stage filtration—mechanical, chemical and biological—through easy-access cartridges and media compartments. It features an adjustable flow control and a compact cascade design that hangs on the aquarium rim, making it suitable for small freshwater and planted tanks where reliable water quality and low maintenance are required.
Advantages
The Fluval AC20 delivers multi-stage filtration in a single compact housing, combining mechanical trapping of debris, chemical polishing and biological colonization space for beneficial bacteria. Cartridges and media are accessible from the top, which simplifies routine maintenance and media replacement. Adjustable flow lets you tailor circulation to tank inhabitants and plant needs, while the hang-on cascade layout saves internal tank space and reduces visual clutter.
Suitable for
 Small freshwater aquariums 18–76 L
 Planted tanks that require moderate circulation without strong surface disturbance
 Nano or desktop aquariums where internal space is limited
 Fish or invertebrate setups needing stable mechanical, chemical and biological filtration
When it may not be suitable
This filter is not intended for larger aquariums above the stated capacity range or for heavily stocked systems that require very high turnover rates. It may also be insufficient if you need extremely powerful flow for large plant species or for systems with heavy bio-load; in those cases, a larger or additional filtration unit should be considered.
Key specifications
 Recommended aquarium volume: 18–76 L
 Filtration stages: mechanical, chemical, biological
 Flow control: adjustable output to regulate circulation
 Design: hang-on cascade style that mounts on aquarium rim
 Maintenance: top-access cartridges and media compartments for easy replacement
 Intended use: freshwater and planted aquariums, small community setups
How to use
Mount the Fluval AC20 on the aquarium rim according to the included instructions, ensuring the intake is submerged and the unit sits level. Prime the unit if required, plug it into a grounded outlet, and adjust the flow control to achieve the desired circulation without causing excessive surface turbulence. Replace or clean mechanical media regularly to prevent clogging, refresh chemical media according to manufacturer guidance or water test results, and allow time for biological media to establish beneficial bacteria after installation or media changes.
What to consider before purchase
 Verify aquarium dimensions and tank volume to confirm compatibility with the 18–76 L range
 Assess stocking levels and plant species to determine whether adjustable flow is sufficient
 Consider access to power and space behind the aquarium for hang-on installation
 Plan for periodic cartridge or media replacement and routine maintenance
Usage recommendations
For stable water conditions, set the flow at a moderate rate to balance filtration efficiency and gentle water movement for fish and plants; perform regular partial water changes and inspect cartridges monthly, replacing chemical media when water tests indicate declining quality.
