As now is the first of March its worth reminding everyone with a uv filter system to remember to replace their UV bulb over the next few weeks.
The bulb should be replaced annually just before the growing season starts.
UV bulbs are not all the same, so you need to know which type you have. If you are not sure, find out the manufacturer of your system and the model and do a quick search.
NOTE: before changing bulbs make sure you turn off the electricity supply going to it.
