Description
XFLO XFL6‑300ML‑2 UV Sterilizer | 300 W Ultra‑High‑Output Ultraviolet Reactor • 6″ Diameter Chamber • Premium Aquarium & Pond‑Grade
The XFLO XFL6‑300ML‑2 is a top‑tier UV‑C steriliser engineered for very large aquariums, ponds and industrial or aquaculture systems. Featuring a 300 watt total UV power (2 × 150 W lamps) in a 6″ diameter reactor body, this unit delivers exceptional flow capacity and microbial control—ideal for high‑volume systems where clarity, health and throughput are critical. It incorporates XFLO’s advanced “L‑shaped” flow path, large unionised plumbing and easy‑access maintenance design—blending professional performance with service‑friendly installation.
Key Features
-
300 W UV‑C dual‑lamp configuration — Designed for very large systems or high‑turnover water volumes.
-
Optimised “L‑shaped” flow path — Ensures excellent hydraulic mixing, minimising “dead” zones and maximising UV exposure.
-
6″ diameter reactor body — Allows high flow while still maintaining effective exposure and treatment time.
-
Unionised water ports (standard on 6″ models) — Simplifies plumbing and servicing with standard union fittings.
-
Single‑ended lamp & quartz sleeve access — Enables lamp or sleeve servicing/replacement without full dismantling of the front housing.
-
Tool‑free, no‑twist lamp cable fittings — Prevents cable damage during maintenance.
-
Premium lamps & durable materials — Uses hard‑quartz, non‑ozone‑emitting lamps to reduce scaling and maintain UV transmission over time.

Applications
-
Large public‑aquarium setups, commercial aquaculture or recirculating systems needing robust UV sterilisation.
-
Very large ponds or water‑features where high volume and high flow demand powerful treatment.
-
Environments where chemical‑free microbial reduction is required across large water volumes.
-
Systems prioritising maintenance ease, high reliability and long operational uptime.
Benefits
-
Superior water clarity & microbial control — The high wattage dual‑lamp system plus the optimised flow path provide strong sterilisation of algae, bacteria, parasites and other waterborne organisms.
-
Extremely large‑system capacity — With the 300 W configuration and high flow rating, this model supports some of the largest aquarium or pond installations.
-
Service‑friendly design — Union ports, single‑ended access and tool‑free lamp cables make maintenance simpler and faster.
-
Premium construction — Built with quality materials and designed for professional use and long service life.
-
Chemical‑free sterilisation — Delivers UV‑C disinfection without adding chemicals, making it ideal for sensitive aquatic life, plants or high‑end display systems.
Installation & Maintenance Tips
-
Install this UV steriliser after mechanical and biological filtration so the water entering the unit is as clear as possible — this maximises UV penetration and treatment efficiency.
-
Ensure the flow through the unit remains within the recommended range; excessive flow reduces exposure time and may compromise sterilisation effectiveness.
-
Replace UV lamps at the manufacturer’s recommended interval (often yearly) even if visible brightness appears fine — UV output declines over time.
-
Clean the quartz sleeve periodically to remove scaling, biofilm or mineral build‑up which can block UV light and reduce performance.
-
Ensure all unionised connections are tight, sealed and leak‑free; inspect seals regularly during maintenance.
The XFLO XFL6‑300ML‑2 UV Sterilizer offers ultra‑high‑capacity UV‑C performance for the most demanding aquatic systems. Whether for large aquariums, expansive ponds or commercial recirculating setups, the model delivers outstanding sterilisation, large flow capability and service‑oriented design. If you need chemical‑free, high‑throughput UV treatment in a premium package, this model stands out as a powerful choice.
