If your pond is turning green again, your UV tube is no longer operating at peak strength.
Even when a UV globe still lights up, its UV-C output weakens over time. The Ultra Zap UV Clarifier Replacement Tube restores the full algae-killing power of your system, helping you maintain clear, healthy pond water without chemicals.
Consistent replacement is the difference between ongoing clarity and recurring algae problems.
Why Replace Your UV Tube?
- UV intensity drops long before the globe stops glowing
- Essential for controlling free-floating algae
- Prevents green water outbreaks
- Maintains safe, chemical-free water treatment
- Supports healthy koi and ornamental fish
For UV systems running continuously, replacement is recommended every 9 months to ensure optimal performance.
Recommended Maintenance
- Remove and wipe globes monthly for best results
- Clean immediately if water quality deteriorates
- Replace tubes every 9 months for consistent UV effectiveness
Routine maintenance protects your investment and keeps your pond water clear year-round.
