Oase UVC Philips Bulb 9 W TC-S G23

Replacement bulb for UV-C water clarifiers.

If your pond or aquarium water turns greenish or cloudy, the culprits are usually microorganisms, algae, bacteria or viruses. You can reduce the number of germs with a UV-C clarifier, as the UV-C light has a disinfecting effect on the water. Cloudiness and unpleasant odours are quickly dissipated. Replace the UV-C bulb at least once a year, as it loses luminosity over time and therefore its effect.

Expert Oliver Knott recommends:
With the UV-C replacement bulb, you can achieve clear and germ-free water in your pond and aquarium where fish and other aquatic life can feel at home.
