The benefits of UVC - newbie question

Gill,

We use a Tetra UV to kill the algae. Works fine and is not really
needed all season. It is much nicer for us than waiting for the algae
bloom to pass. Some would feel that it is better to let the bloom
kill itself off. That can take a long time, so we have gone to a UV.
With great results.

We would support the idea of being on the hogh side for strength.
Killing algea faster is fine. Failing to kill it off is a bummer.

Do you use it just to kill off the algae or do you find that, as it does
in a marine tank, that it also kills off pathogens, parasites and other
nasties....or do you use alternative control methods for these such as
PP dosing?

========================
We also have the Tetra units. The bulbs are at least 6 years old and they
still work like a charm on algae. One is already running as I type this. I
only run them as needed.

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!

Do you keep your UVC on all the time?


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

My understanding of UV usage in the marine aquatic side is that it is
used for prevention of parasites etc. Does the same theory apply to
Ponds as well with this UVC unit? Or is it just a water clarifier?

Just addressing this question to my understanding, mostly they are used as
a clarifier. They have to be of high wattage to kill parasites, and
considering the volume of water, not many people go there. Not to mention
we're talking outside where lots of parasites can enter the water at all
times. Thus it is more important to make sure water parameters are great
and fish have healthy immune systems.

I don't use UV.... if the plant to fish ratio is balanced it isn't needed.
Unfortunately most tend to hit a pond shop and go, "Oh pretty! I'll take
10!" And it isn't plants they're looking at. ;-) ~ jan

So, do you routinely treat the water for parasites, with PP or an
off-the-shelf product? Or do you find it a sufficient safeguard to trust
on the health of the fish and the water parameters?

It is unlikely that I will keep making new fish additions (except any
they care to make for me - lol) but there is no way of preventing frogs,
newts etc from making the pond their home....now plants are a different
matter - he, he

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 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
