Yamitsu 25w

If green water keeps returning during warmer months, stepping up UV wattage can make the difference. The Yamitsu 25w UV is an inline ultraviolet clarifier designed to control free‑floating algae and support clearer pond water.

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

What it does

• 25 watt UV-C lamp
• Targets free‑floating green water algae
• Supports improved water clarity
• Designed for inline installation

UV clarification improves clarity but works best alongside effective mechanical and biological filtration.

Installation Guidance

• Install inline after the pump and before the main filter
• Match flow rate correctly to ensure proper UV exposure time
• Mount securely and protect electrical components from water ingress

Maintenance & Safety

• Always unplug before servicing.
• Replace the UV lamp annually for consistent output.
• Clean the quartz sleeve periodically to prevent limescale build-up.
• Check seals and end caps during maintenance.

The Yamitsu 25w UV offers dependable green water control when correctly installed and maintained — helping you maintain clearer, healthier pond conditions.
