Understanding UV Light Filters

When I first considered a UV light filter for my aquarium, I wanted to ensure I fully understood what it was and how it worked. UV light filters use ultraviolet light to eliminate harmful microorganisms in the water. They help to maintain a healthy environment for my fish and plants by breaking down algae and bacteria.

Benefits of Using a UV Light Filter
