UV Filters

By mutex ( April 17, 2010 at 3:07 pm) · Filed under Equipment,

A UV filter is a device that exposes water flow to ultra-violet light.  UV light, in the proper intensity, will kill microorganisms like bacteria, viruses, algae, and parasites present in water.  For aquariums, there are generally two types of UV filters:

  • Those with an integrated pump or requiring a dedicated pump to push water through the UV filter
  • Those that attach to the output of a canister filter.

UV filters can be quite effective at:

  • Eliminating “Green Water” algae
  • Killing off internal and external parasites, including Ich.
  • Preventing  bacterial infections, particularly in tanks that are not kept clean.
