Jebao Pond & Aquarium UV Clarifier STU-36 36W Stainless Steel — External Unit with Weather‑Resistant Transformer & Multiple Adapte

The Jebao STU-36 is a 36-watt stainless steel, non-submersible UV clarifier designed to reduce green water and improve clarity in ponds and aquariums up to about 8,800 gallons.

The Jebao STU-36 Stainless Steel Pond and Aquarium Clarifier uses a high-performance 36W UV lamp housed in a durable stainless steel body to treat water moving through your pond or filtration system. It installs externally (non-submersible), works with common hose and PVC sizes, and includes a weather-resistant transformer and multiple fittings to match existing plumbing. The unit is engineered for seasonal use and straightforward bulb replacement to keep performance consistent.

How does the STU-36 help reduce green water?

The clarifier exposes flowing pond water to ultraviolet light that targets free-floating microscopic algae and suspended organic particles, helping them clump and be removed by your filter or settle out. It does not add chemicals; instead it relies on UV treatment to improve visible clarity and reduce the ongoing cycle of green water.

• 36-watt UV lamp rated up to about 8,000 hours of operation
• Non-submersible stainless steel chamber for external plumbing
• Effective for ponds and water gardens up to ~8,800 gallons depending on turnover
• Includes multiple hose adapters and a 2" PVC adapter for flexible hookups

What are the installation and maintenance requirements?

Installation is straightforward: mount the unit vertically or horizontally in a dry location out of direct sunlight, connect plumbing with the provided fittings, and plug into the included transformer. Routine maintenance is limited to replacing the UV bulb around every 6–12 months depending on use and replacing it after approximately 8,000 hours for optimal effectiveness.

• Can be mounted vertically or horizontally to suit plumbing layout
• Includes 1", 1-1/4", 1-1/2" hose fittings plus 2" PVC adapter
• 22 ft. cord with weather-resistant transformer — avoid direct sun exposure
• Bulb replacement recommended after ~8,000 hours (about 11 months continuous)

Will the STU-36 work with my existing pump and filter?

The unit is designed to integrate with most external plumbing setups; it treats water passing through the clarifier and is most effective when paired with mechanical or biological filtration to remove the particles aggregated by UV light. Ensure your pump provides sufficient turnover for the pond volume you intend to treat to maximize clarity benefits.

• Works best when water turnover matches pond size and clarifier capacity
• Pairs with mechanical filters to capture flocculated particles
• External, non-submersible layout keeps unit accessible for service
• Check hose or PVC diameter and select included adapter accordingly

How long does the unit and lamp last, and are replacements available?

The stainless steel housing is built for outdoor, non-submerged use and should provide durable service when installed per instructions; the lamp is the primary consumable and should be replaced after roughly 8,000 hours for consistent UV output. Replacement bulbs and parts are commonly available and simple to swap with basic hand tools.

• 36W lamp life rated up to ~8,000 hours; replace for peak performance
• Stainless steel chamber for corrosion resistance in external installations
• Weather-resistant transformer with long cord for flexible placement
• EPA Establishment Number: 97745-CHN-1 (for reference)

Who is this for? The Jebao STU-36 is aimed at pond and water-garden owners, hobbyists with larger aquariums, and landscapers who want an easy-to-install external UV clarifier to reduce green water and help maintain clearer water without chemicals. It suits systems where external mounting is preferred, and where periodic lamp replacement and basic plumbing integration are acceptable parts of routine maintenance.
