How to clean a pond UV light filter
Blog post written by Gary | 03 June 2014 | Category: Pond maintenance
Many customers find that even when they have a UV light filter fitted to their pond filter system the pond water remains or still goes green with algae.
If the UV light filter is the correct size for the pond and is working normally, then either the UV lamp needs replacing and/or the quartz glass has become dirty, reducing the amount of UV radiation reaching the algae and allowing the algae to multiply very quickly.
The UV lamp should be replaced every year ideally in the spring, giving full radiation output throughout the spring, summer and autumn when the sun is at its strongest.
When changing the lamp it is best to inspect the quartz sleeve for a buildup of hard water deposits and dirt. This should be cleaned from the quartz glass carefully as the quartz glass sleeve is very fragile.
We have taken a series of photos to show how a TMC UV filter is dismantled ready for a lamp change and glass clean.
