Product Information
Full details
The Lotus 15/25w Quartz Sleeve is designed for pond owners using Lotus, Oasis, and AquaTeck UV filtration systems who need to maintain optimal water clarity. This essential replacement part protects your delicate UV bulb from direct contact with water while ensuring maximum light transmission for effective algae control. A primary caveat is that some higher-capacity models require two sleeves for a single unit, so ensure you check your specific filter manual before starting your maintenance.

FAQs
How do I know if I need one or two sleeves?
Check your UV unit model manual; units like the Green Genie 48000 and Clear Pond 50 require two sleeves to function correctly.
Can I use this with non-Lotus filters?
It is specifically designed for Lotus, Oasis, and AquaTeck units. Compatibility with other brands is not guaranteed.
How often should I clean the sleeve?
Ideally, clean it every time you perform routine maintenance on your filter sponges or when you notice a reduction in water clarity.
Is it normal for the sleeve to get cloudy?
Cloudiness is usually due to mineral deposits. Regular cleaning with a mild, non-abrasive cleaner or vinegar will restore clarity.
Does this package include the UV bulb?
No, this is only the quartz sleeve replacement. The UV bulb must be purchased separately.
Troubleshooting
Water inside the quartz sleeve
The O-ring seal has likely failed. Inspect and replace the rubber O-rings and ensure the locking nut is tightened securely.
UV light appears dim or ineffective
Clean the exterior of the quartz sleeve to remove algae or limescale buildup that may be blocking the light.

Setup, Compatibility & Care
Before installation, ensure your power supply to the UV unit is completely disconnected. Carefully slide the quartz sleeve into the UV housing, ensuring that all rubber O-rings are seated correctly to provide a watertight seal. Never touch the glass with bare, oily hands; use a clean, dry cloth to prevent oils from burning onto the glass. This product is compatible with the Lotus Green Genie 24000, 30000, and 48000, as well as the Lotus Green 2 Clean and Clear Pond 25/50 series. Always check if your specific model requires one or two sleeves before purchase.
