Oase Filtoclear Replacement Quartz Tube

You should replace the quartz tube if it becomes cracked, chipped, or heavily clouded with mineral deposits that cannot be cleaned off. A damaged or dirty tube prevents UV light from effectively reaching the water, which will lead to green water and algae blooms.

This specific quartz tube is designed for the Oase Filtoclear G2 and G3 series. Because Oase manufactures several different sizes, you must verify your specific Filtoclear model number—typically found on a sticker on the top of the unit—to ensure it matches the required wattage and tube length.

Yes, this replacement quartz tube is also compatible with the Vitronic 18-watt and 36-watt UV clarifiers. Always double-check your specific Vitronic model specifications against the tube dimensions before purchasing.

While not strictly required, it is highly recommended to replace your UV lamp whenever you install a new quartz tube. UV bulbs lose their effectiveness over time, and since you are already opening the housing, replacing both ensures your system operates at peak efficiency.

Use a soft cloth and a mild, non-abrasive cleaner specifically designed for aquarium or pond equipment to remove mineral buildup. Avoid using harsh chemicals or abrasive scouring pads, as these can scratch the glass and reduce the transmission of UV light.
