Today's Pond Q&A
In this issue:
- When to start up the pond after winter
- Pond UV question and pond sizing
Is it OK to run my large waterfall during the winter? I have an
article that it is nice to have the waterfall run all winter
because it looks so good. But, I ready an article from you saying
to leave everything off and only run a heater to keep a hole open
thought the ice so the fish are not bothered by the running water
as they are almost dormant.
When do you think I should start my 12000 gallon pond up. By
turning on all the underwater pumps? I know not to feed my fish
until the water temperature is over 50 degrees. So should I wait
to do everything at the same time?

Yes, you can run your waterfall during winter, but your fish
would prefer it to be nice and quiet while they're hibernating.
I have general rule that anything that causes *less* stress on
the fish is the better way to go. The other reason it's best to
leave the waterfall off is because during winter, you will still
have 'thermal layers' in the pond water, where the water closer
to the surface will be coldest, and the water toward the bottom
will be several degrees warmer.
By running your waterfall pumps, you are re-circulating all this
water and actually making the water *colder* where the fish are
sleeping at the bottom. Again, less cold equals less stress
equals happier fish..
But if you really want to see the waterfall running in winter,
and that is a primary reason for having the pond in the first
place - it's your call. As far as when to turn everything back
on, I usually recommend waiting until the weather is back into
the 50's and you're ready to start feeding the fish again. A
partial water change is also a good idea, and will really
'refresh' your fish and help get the pond ready for spring.
Remember to de-chlorinate your water with a good product like
Ammo-Lock II or Amquel.
Hope this helps,
