most people say they kill the algae, but my UV is too weak to do that and I have read
that UV damages the cell wall of algae so they clump together and get filtered out.
I dont change my bulb UNTIL it looks like it isnt handling the algae. actually, I
didnt change my first UV unit bulb at all. the wires rusted off (it was a used one
somebody gave me). the people who sell bulbs recommend replacing it every year, but
I think replacing it when it doesnt do the job is a cheaper idea.

Can anyone tell me what does a UV light actually do to the water & why do
you have to change the UV bulb/tube and how often do you have to change the
bulb/tube.
Thanks
