Measuring 13 x 29.5 x 10.5 cm, it treats aquaria water up to a maximum of 1500 liters to reduce free-floating algae and pathogens by exposing water to germicidal UVC light. It mounts into existing filter plumbing to improve water clarity and support fish and plant health in freshwater setups.

## Long description

The Fluval FX UVC in-line clarifier is a 6W UVC sterilizer designed to integrate with Fluval FX and Series 7 external filter systems. Sized at 13 x 29.5 x 10.5 cm, it is intended for freshwater aquaria up to 1500 litres and connects directly into existing filter plumbing to expose circulating water to germicidal UVC light, reducing suspended algae, free-floating microorganisms and certain pathogens to improve water clarity and help maintain a healthier environment for fish and plants.
Advantages
The unit provides continuous in-line UVC sterilization without requiring a separate stand-alone device, conserving space and simplifying plumbing by mounting directly into the filter loop. With a 6W UVC lamp in a compact housing it targets free-floating algae and microbes as water passes through, supporting clearer water and potentially reducing the need for frequent manual cleaning. The clarifier is engineered to match Fluval FX and Series 7 flow characteristics, ensuring consistent exposure time for effective treatment in systems up to the stated volume.
Suitable for
Freshwater aquaria up to 1500 L where improved water clarity is needed
Owners using Fluval FX or Series 7 external canister filters seeking integrated UVC treatment
Systems with established plumbing loops that can accommodate an in-line sterilizer
When it may not be suitable
The Fluval FX UVC clarifier is not intended for direct use in saltwater reef systems where different biological balances and equipment requirements apply. It is also not a substitute for good mechanical and biological filtration; UVC reduces free-floating organisms but does not remove debris or resolve underlying water quality issues such as excess nutrients.
Key specifications
UVC lamp power: 6 W
Maximum aquarium volume: up to 1500 litres
Dimensions (W x L x H): 13 x 29.5 x 10.5 cm
Installation: in-line mounting into external filter plumbing
Intended water type: freshwater aquaria
How to use
Install the in-line unit into the return or intake plumbing of a compatible Fluval FX or Series 7 external canister filter following the manufacturer's plumbing orientation and flow direction. Ensure all connections are secure and leak-free before powering the unit. Operate the sterilizer continuously while water circulates through the filter to maintain exposure to germicidal UVC light; periodically inspect the lamp and quartz sleeve and replace components as recommended by Fluval to sustain UVC output and effectiveness.
What to consider before purchase
Confirm compatibility with your Fluval FX or Series 7 filter model and available plumbing layout
Verify aquarium volume does not exceed the stated maximum treated capacity of 1500 L
Plan for periodic lamp and sleeve maintenance or replacement to maintain UVC performance
Usage recommendations
Use the Fluval FX UVC in-line clarifier as part of an overall filtration strategy: combine mechanical and biological filtration, regular water testing and maintenance, and appropriate stocking levels. Avoid relying solely on UVC for water quality; maintain routine cleaning and water changes to address nutrient sources that promote algae growth.
