Hi
I put in a new 900 gal. pond last fall with a Biofalls filter/waterfall.
We shut it down for the winter and used a Thermopond de-icer, which worked
great! I have Shubunkins/snails/frogs.

Should I start up my biofalls now? The pond is ice free, but still cold
up here in SW Ontario Canada (35-40F deg. days).
(We have seen light snow in April before.)

Light snow in April? In April 1996 I started a job in Michigan, requiring
me to commute from London through Sarnia. I spent that whole first month
driving through blizzards. Now, in the three years I was on that job, that
was really the worst driving I had, but it's definitely not always just
"light" snow. Still, I'd start the pumps.
