The benefits of UVC - newbie question

We found the UV not useful once the fall cold comes...the water is the
proverbial 'gin' (or tea) clear then. We run it in the spring and
as needed other times. It is easy to tell if it is needed to keep the
green water down!

Sometimes ours are gin clear in winter and sometimes one or more will stay a
bit green. As soon as the ice melted last week some of them started to turn
green. They're already up to 50F. The above ground ones that is. They're
out in the sun and the plants are still dormant so the algae starts right
up. I want to keep this one 650g tank clear as the fry are undersized. I
fed them today and any day they'll eat regardless of temperature. So far so
good. I'm trying to keep them alive until spring. They should make it if we
have a normal spring and no more real cold snaps.

Ordinarily the 3 fry tanks can go green as the grass because no one sees
them but me. :-) I check them when they come up to eat.

I don't imnd the algae that grows on the preforms or liners walls etc,
its the green bloom I do not like. I think cool or cold weather is
the only time a pond at least a natural pond or most larger ponds in
the deep south are really clear.......I know my pleco's love the algae
build up on the ponds sides.....So far I have weathered outside 8
pleco's for over 4 years now, and all are well over the 16" mark in
size......I also have a few smaller 12" and under outside for the
first time this year and they appear to be doing well, however I htink
with ideal conditions for growing this carpet algae, and the
metabolism of the plecos in colder water, they just can not keep up
with the algae as they can in summer time Just yesterday the wife and
I went to town, and took the long way home, and we both remarked how
nice all the ponds and such were........however in a few months they
will be all green and turbid once the warm weather sets in.
