Germicidal lamps need to be changed once a year for you to maintain clear, algae and bacteria free water in your garden pond. Knowing which bulb fits which pond filter can be tricky so we’ve listed the most common Hozelock filters and matched them to our replacement germicidal PLS TUV UVC (ultra violet) bulbs.

Choose your filter from the list below:

Alternatively, if you know which lamp you are looking for you can browse by type:

• Germicidal Tubes - T5,T8 & T10 diameters 
• Germicidal UVC Compact Fluorescents - PLS & PLL in varying wattages 

Please note Germicidal Lamps emit UVC radiation at 253.7nm that is dangerous to the human eye. These lamps should not be used for general illumination
