Re: UV sterilizer
Mike,
I remember a thread on a Discus forum about UV sterilizers.I think the main
setback people mentioned is that a lot of beneficiary micro organisms that
Discus /fish need being killed as well.If you do your waterchanges(WC) and
tank maintenance you should be fine without a UV system.By keeping discus I
really learned about the benefits of regular WC.
It's amazing how fish respond to at least twice a week WC.
Sorry for just throwing that in here.I should try to find the discussion
again.It was pretty interesting.

Matt,
I see nothing wrong with using a UV system. The main reason you don't see
them used a lot on freshwater tanks is their expense. UV bulbs need to be
regularly replaced - every 3 - 6 months. After that, they aren't really
effective. In general,
freshwater fish are more adaptable to water chemistry than marine fish.
Because of this they tend to be less stressed by less-than-optimal water
conditions. It is virtually impossible to keep a small volume of marine
water in this condition, so
marine fish tend to be more susceptible to diseases in our aquaria. UV
sterilization helps reduce the number of pathogens in the water. Thus less
likelihood of catching something.
UV sterilizers will kill anything that flows through the housing that
carries the UV bulb. Since the bacteria running your biological filter
doesn't float in the tank, it is safe.
