Jebao Pond and Aquarium UV Clarifier CW-55 — 55W In-Line UV Sterilizer for Up to 5,000 gal, High Flow

The Jebao CW-55 is a 55-watt, non-submersible UV clarifier designed to reduce suspended algae and pathogens in ponds and aquariums up to 5,000 gallons when installed in-line.

If you want clearer water without constant chemical treatments, the CW-55 delivers continuous ultraviolet clarification using a high-output 2G11 55W lamp housed in an easy-to-service quartz sleeve. It installs outside the water as an in-line unit, connects to common tubing sizes, and supports high flow rates so it integrates with existing pumps and filtration setups. The unit is built for routine maintenance: the quartz sleeve is removable for quick cleaning and the lamp is user-replaceable after roughly 8,000 hours of use (about 11 months at continuous operation).

How does the CW-55 improve pond and aquarium water clarity?

The UV lamp emits germicidal wavelengths that damage single-celled algae and many microorganisms as water passes the lamp, reducing visible bloom and suspended particles. It doesn’t filter debris, so it works best combined with mechanical and biological filtration.

• 55-watt UV lamp (2G11 base) for strong irradiation
• Effective maximum pond capacity with fish: up to 5,000 gallons
• Max flow rate: 5,000 GPH for high-throughput systems
• In-line design treats water while circulating, no submersion required

What plumbing and electrical connections does it need?

The CW-55 fits a range of common tubing sizes and runs on standard household power, so it connects easily to most pond pumps and garden plumbing. A 16-foot power cord gives flexible placement outside the pond area.

• Includes hose tails for 3/4", 1", 1-1/4", and 1-1/2" tubing
• Power specification: 110V / 60Hz with 16' cord for convenience
• In-line or out-of-water installation — mount on a stable surface near plumbing
• Compact footprint: 25" long x 5.75" wide for tight equipment bays

How do you maintain the UV clarifier for reliable performance?

Routine care keeps the lamp output high and prevents scaling from reducing effectiveness. The CW-55 is designed for straightforward upkeep so you can minimize downtime.

• Remove and clean the quartz sleeve quickly for routine maintenance
• Replace the 55W lamp after ~8,000 hours (about 11 months continuous use)
• Keep fittings tight and inspect O-rings to prevent leaks
• Follow local disposal or recycling rules for used lamps

Will the CW-55 work with fish and delicate ecosystems?

Yes — when sized and installed correctly the UV clarifier reduces free-floating algae and some microorganisms without directly harming fish or plants. It should be part of a balanced system alongside filtration and water-quality monitoring.

• Rated for ponds with fish up to 5,000 gallons when flow and exposure are appropriate
• Non-submersible operation keeps electronics and lamp housing dry
• Use alongside mechanical filters to remove dead cells and debris
• Monitor water chemistry and biological filtration to maintain ecosystem balance

Who this is for: The Jebao CW-55 suits pond and water-garden owners, aquaculture hobbyists, and aquarium hobbyists who want a robust in-line UV clarifier that pairs with existing pumps and filters. It’s ideal if you need a high-flow-capacity unit for larger hobby ponds (up to 5,000 gallons) and prefer an external installation that’s easy to access for lamp replacement and sleeve cleaning. Professionals maintaining garden water features or koi ponds will appreciate the commercial-style lamp output and the inclusion of multiple hose tails for flexible plumbing. Note: the product carries EPA establishment number 97745-CHN-1; follow local regulations for lamp disposal and safety.
