A UV light in a pond helps to combat unsightly green water algae. We recommend replacing your fish pond uv bulb every 6- 12 months to maintain optimium performance.
TIP: Change your lamp at the beginning of every pond season(March to April) to ensure the bulb is at full strength during the warmer sunnier months.
