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.

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.

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!

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.

This is my first year with a pond. Contrary to advice I read,
because it has been a mild winter, I've kept pump/filters/UV running
all the time. The pop-up on the filter is half way up, so it must
have been doing some good. I have a newlamp ready to put in
.......prob at easter.

What brand do you have? and is it a combined unit?

TIA

I cover my pond with plastic in winter and I use a 500watt heater in 1600 gallon
pond so I can feed my fish a little bit every 4th day or so almost all winter. last
time was Jan. 5th. been too cold since then. My ponds are netted all year. I
havent had to treat my pond since 2000. Before the plastic and heater my fish
wouldnt eat for nearly 6 months, I think that is very hand on them. also, once it
warms up the temp stays even so there isnt so much up and down which also prevents
problems. Ingrid

So, do you routinely treat the water for parasites, with PP or an
off-the-shelf product?

My drug of choice is Prazi in the spring & fall for flukes, Koizyme and
then salt. None of which affect the filter. I haven't needed to treat the
lily pond with goldfish at all... and that's where all the frogs are coming
and going. ~ jan

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.

One of our members also covers with plastic, I think he used an 800 watt,
for 4,000 gallons and managed to keep it around 50F (Zone 7), so he's been
feeding all winter. His fish were large last fall, can't wait to see this
summer the difference. I know that is his goal, to grow some big ones. :-)

Spring is coming, just got an E to get my order of Manda Fu requested. One
of our members orders them all in so we save on shipping. :-) ~ jan

For what its worth in this reigon, as it really never freezes, and if
it did the ice would be gone by 9am once sun is up , the folks in the
high rent district use those solar panels of what looks like bubble
wrap...(blueish green with silver mylar reflective area) thats used to
heat up swimming pools etc by solar power. The local swimming pool
supply stores here sell it in large rolls that they can piece to
gether to make a cover essentially in the shape and size of your
swimming pool, or inthe case of a pond the shape and size of your
pond. I had a bout a 3 x 3 foot piece of it and will say it does
absorb heat and direct it into the water, and it does make a
difference.
