Product Information

Swell 25 watt T5 single ended 4 pin UV replacement Bulbs/Tubes are compatible with the Laguna filters.

By using the UV light to treat algae and pathogens in the water, cloudy or green water problems can be resolved. The Ultra Violet lights force the algae cells to clump together and as such are easier for the filter to remove. The pond water becomes clear and provides the ideal habitat for fish and other pond inhabitants.

Swell bulbs use only the highest materials in their replacement bulbs, and by using high-quality UVC lamps to guarantee a long service life. You'll find that our products perform more than favourably with the leading manufacturers.

It's always better to be prepared, especially in the warmer months when algae can become a real problem.

Key Features:

  • Single ended 4 pins in one end.
  • High UV output allows for greater algae control.
  • Measurements 45cm long.
