Swell 25 Watt T8 Double Ended UV replacement Bulbs/Tubes.

In the summer months, algae can become a real nuisance in a garden pond and quickly decimate your once beautiful pond. Ultra Violet lamps work by treating the algae cells and forcing them to mass together for easier removal.

Swell bulbs use only the highest materials in their replacement bulbs, and using high-quality UVC lamps guarantees long-lasting performance. For added value, if you buy one you get another free, so you can be confident that your pond or aquarium is covered!
