UV-Transmitting Quartz Sleeve for the Filtral 800 The Oase Filtral 800 quartz glass protects the UV clarifier lamp while allowing ultraviolet light to pass through and eliminate algae spores and pathogens. Over a season of operation, mineral deposits and biological film accumulate on the glass surface, reducing UV transmission and compromising water clarity. Annual Replacement for Best Results Replacing the quartz sleeve every spring — together with the UV bulb — is the most effective way to ensure your Filtral 800 keeps green water under control all season. Even a thin film on the glass can reduce UV intensity enough for algae to survive the chamber. Specification Details Compatible Model Filtral 800 Material High-purity quartz glass Installation Disconnect power and remove the Filtral from the pond. Extract the UV lamp, slide out the old sleeve, and insert the replacement. Handle with clean gloves. Reassemble and submerge. Ideal for Filtral 800 owners performing annual UV maintenance during spring startup.
