does bio-filter need light?

[ryf]

I don't know what to search for to answer this, I tried that, not sure what the other verbage/organisms names are. simply put, can you have a biofilter in the cabinet without a light? I am aware it needs air (like bioballs, etc)

planning to use "Seachem Matrix Bio" I have used this mixed in with gravel before.but never in a remote filter. thanks for looking.

if theres a term to search for to answer this, that would help as well for the future, thanks!

(yes I know it's wikipedia, but still a good source of info!)

Edit: found some more info:
http://www.bioconlabs.com/nitribactfacts.html
Nitrifying bacteria are photosensitive, especially to blue and ultraviolet light. After they have colonized a surface this light poses no problem. During the first 3 or 4 days many of the cells may be suspended in the water column. Specialized bulbs in reef aquaria that emit UV or near UV light should remain off during this time. Regular aquarium lighting has no appreciable negative effect.

yes..UV light is used to sterilize bacteria from a water column. the idea tho is to make sure the bacteria is exposed for at least the minimum exposure.

oxygen and a food supply is all you need

light will let algae start to grow which can be unsightly, smelly, and detrimental for the biological filter.
