Re: UV Sterilizer for fighting algae and better fish health

An UV filter wont help against the type of algae you describe. It will only
help against free floating micro algae like the type that makes the water
green.. It wont stop attached organisms from spreading offspring to other
parts of the tank.
It could help increasing the health level of your fish if they are plagued
by micro organisms in the water like fungus and bacteria. For example fin
rot, wounds, white "cotton" dots etc. But this should not be a problem if
the tank is well cycled and doesn't have to many fish because the imune
system of warm water fish should be able to deal with that.
It doesn't sound like an UV filter is what you need. Maybe less fish per
volume and more water changes. That won't make the algae go away, but it
could make them grow slower.
