Choosing the correct UV bulb or lamp is essential for keeping your aquarium or pond water healthy and clear. These bulbs are designed to fit all popular quality manufacturer products, but it’s important to check the dimensions of your existing bulb before purchasing.


Recommended UV Bulb Replacement

  • Sterilisation purposes: Replace every 6 months (approx. 4,000 hours) to maintain optimal performance.

  • Clarification purposes (pond or aquarium): Replace every 12 months (approx. 8,000 hours).

  • Additional tip: When changing your UV lamp, it’s recommended to clean the quartz sleeve to ensure maximum efficiency.
