Product Information

Swell 4 watt T5 Double Ended UV replacement Bulbs / Tubes are compatible with a wide variety of pond equipment from most major brands including Oase, Blagdon, Fish Mate, Hozelock and Aqua Medic.

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 guarantees 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. So when you buy a UV lamp we throw in another absolutely free!

Key Features:

  • Double ended tube with two pins at either end.
  • High UV output allows for greater algae control.
  • Buy one get one free!

    This is a replacement bulb so I know it is perfect for the job. What's even better I bought it when it was B.O.G.O.F. How's that for value!
