When a UV lamp ages, water clarity suffers. These replacement UV bulbs restore your UltraZap sterilizer to full performance — pick the wattage to match your unit. Fitting is straightforward: swap out the old tube and your pond, aquarium or fish tank is back to clear. UV lamps lose output over time even while they still light up, so replacing the tube is standard maintenance.

Good to know:
– Four wattages: 8W, 15W, 30W and 55W
– Fits the UltraZap pond UV sterilizer range
– A simple swap to restore clarity
– Check your unit’s wattage before ordering
