Evolution Aqua Evo 25w UVC

If green water is reducing visibility in your pond, a correctly sized UV clarifier helps bring clarity back under control. The Evolution Aqua EVO 25w UVC is an inline ultraviolet unit designed to target free‑floating algae in pumped pond systems.

As water passes through the unit, the 25 watt UV‑C lamp exposes single‑cell algae to ultraviolet light. This causes algae to clump together so they can be removed by your mechanical filtration.

What it does

• 25 watt UV‑C output
• Targets free‑floating green water algae
• Designed for inline installation
• Supports clearer pond water

UV clarification improves clarity but works alongside mechanical and biological filtration — it does not replace them.

Installation Guidance

• Install inline after the pump and before your main filter
• Match flow rate correctly for effective UV exposure
• Mount securely in a dry, ventilated area
• Ensure all unions and seals are watertight

Positioning before the biological stage ensures algae are treated before entering your main filter.

Maintenance & Safety

• Always unplug before servicing.
• Protect eyes and skin from direct UV exposure.
• Replace the UV lamp annually to maintain output.
• Clean the quartz sleeve regularly to prevent mineral build-up.

The Evolution Aqua EVO 25w UVC offers dependable green water control for small to medium pond systems, helping maintain clear and stable water conditions.
