Replacement Aqua UV Sterilizer Quartz Sleeve

All uv sterilizers have a quartz sleeve to protect the lamp from coming in contact with water. Replacing the quartz sleeve at the same time as the lamp in an Aqua Ultraviolet sterilizer helps ensure the unit continues to operate at peak efficiency. Over time, mineral deposits, biofilm, and microscopic scratches can build up on the quartz sleeve, reducing the amount of UV light that passes through to the water. Even if the lamp is new, a worn or clouded sleeve can significantly limit UV transmission and lower the sterilizer’s effectiveness against algae, bacteria, and parasites. Installing a fresh quartz sleeve along with the new lamp maximizes UV output, improves sterilization performance, and helps maintain consistent water clarity and pathogen control in your aquarium system.
