Evolution Aqua Quartz Sleeves

High-Purity Fused Quartz Protection Sleeves for UV Sterilisers and Maximum UV-C Efficiency in Pond Filtration Systems

Evolution Aqua Quartz Sleeves are precision-engineered protective components designed for use within Evolution Aqua UV steriliser systems. Manufactured from high-purity fused quartz, these sleeves serve a critical function in any UV filtration setup by isolating the UV-C lamp from direct water contact while allowing maximum transmission of ultraviolet light into the pond water.

The clarity and purity of the quartz material are essential to system performance. Even minor contamination, scaling, or clouding on the sleeve surface can significantly reduce UV-C penetration, leading to decreased sterilisation efficiency and reduced water clarity. As UV systems operate continuously throughout the pond season, quartz sleeves are subjected to gradual buildup of mineral deposits and biofilm, making routine inspection and maintenance essential.

Designed with open-ended construction and high resistance to thermal stress, scratching, and UV degradation, these sleeves are built to maintain consistent performance under demanding pond conditions. Their role is fundamental in ensuring the UV lamp operates safely, efficiently, and at full effectiveness.

Benefits

• Maximises UV-C light transmission for optimal sterilisation
• Protects UV lamp from direct water contact
• Supports clear and healthy pond water conditions
• Resistant to thermal shock and UV degradation
• High-purity fused quartz for superior performance
• Maintains efficiency of UV filtration systems

When to Use

• During annual UV system maintenance
• When existing sleeve becomes cloudy, scaled, or stained
• When replacing UV lamps as part of routine servicing
• If pond water clarity begins to decline
• As part of preventative UV system upkeep

How It Works

• Forms a sealed protective barrier around UV lamp
• Allows UV-C light to pass through into water column
• Prevents water exposure to electrical components
• High transparency ensures minimal UV loss
• Performance reduces if sleeve becomes contaminated
• Cleaning or replacement restores full UV efficiency

How To Use

• Switch off and disconnect UV steriliser before servicing
• Allow system to cool fully before handling components
• Remove UV lamp carefully to access quartz sleeve
• Inspect sleeve for scaling, clouding, or damage
• Clean gently using appropriate non-abrasive materials if reusable
• Replace if clarity is reduced or damage is present
• Reassemble unit ensuring correct sealing and alignment
• Restart system and verify operation

Matching the aeration system

Aeration works best when the pump, airline and diffuser layout are matched together. Long airline runs, narrow pipe, deep water and too many diffusers can all reduce the airflow that actually reaches the pond. It is better to spread air sensibly across the system than to force everything through one unsuitable point.

Use sinking airline where pipework will run through the pond, keep the air pump dry and ventilated, and allow access for filter cleaning or diaphragm servicing. On koi ponds and larger water bodies, a balanced diffuser layout can improve oxygen distribution and circulation without creating unnecessary turbulence in one area.

Aeration setup notes

Evolution Aqua Quartz Sleeves should be chosen as part of the complete air system, not just by litres per minute. Airline length, airline bore, diffuser depth, manifold taps and back pressure all affect the real airflow that reaches the pond or filter. A well matched aeration system runs more quietly, puts less strain on the pump and gives more dependable oxygen support.

• Use suitable airline size for the pump output and distance involved.
• Keep the air pump dry, ventilated and protected from flooding.
• Spread airflow across multiple diffusers on larger ponds where possible.
• Check diaphragms, filters and diffusers during routine servicing.

For koi ponds, moving bed filters and warm weather aeration, consistent airflow is often more useful than simply oversizing the pump. Balanced diffuser placement gives better circulation and helps avoid stagnant areas.
