Frequently Asked Questions

Q: How often should I replace my FiltoClear UVC bulb?
A: UVC bulbs should be replaced annually, typically at the start of the pond season in spring. Even though the bulb may still light up and appear to be working, the UVC output diminishes significantly after about 8,000-10,000 hours of use (roughly one season of operation). After this time, the bulb won't effectively kill algae or eliminate green water, even though it's still glowing. Replacing the bulb each spring ensures you have maximum algae-fighting power for the upcoming season and is essential for maintaining the crystal-clear water your FiltoClear is designed to deliver.

Q: My bulb still lights up—do I really need to replace it?
A: Yes! This is a common misconception. The visible light you see is not the same as the UVC light that kills algae. UVC is invisible to the human eye and operates at a specific wavelength (254 nanometers) that damages algae DNA. Over time, the UVC output degrades while the visible light remains. So your bulb can look perfectly fine and still be ineffective at controlling algae. If you're experiencing green water despite your bulb lighting up and your filter foams being clean, it's almost certainly time for bulb replacement.

Q: How do I know which bulb I need for my FiltoClear filter?
A: Check your FiltoClear filter model number, which is printed on the filter canister. The Generation 3 models are FiltoClear 3400, 4000, 5200, and 8200. These models all use the same style of UVC bulb, though the wattage may vary by model. When ordering, make sure to specify your exact model number so you receive the correct wattage bulb. The FiltoClear's quick-access design makes bulb replacement easy—you don't need to disassemble the entire filter. If you're unsure of your model, check the label on your filter or contact us with a photo.
