Again, if the combination of your climate and depth of your pond
allows, a deicer is great, but I don't think it fits all situations.
Contrary to what many people think, Koi don't hibernate.

After much research, I've decided to use solar bubble wrap pool cover
floated on the top of my pond and a titanium tube-style heater. The
pool cover will have a border of about an inch to allow gases to
escape. My questions a

1) How do you use one of these acquarium-type heaters? I would imagine
it would burn the pond liner if I just throw it in there. If I suspend
it, I would be concerned of it getting knocked loose. Do I need a
wire/mesh case to keep the fish from burning themselves?

2) I've read bio filters are useless below 50 degree. So I won't run
it. Is it better to remove it from the pond, or just leave it? I
anticipate the heater will keep my pond around 40. I don't intend on
"heating" it, just keeping it from freezing solid.



FYI: I am in zone 5, 500 gallons, 30" deep, 6 Koi

I'll agree with George here. We have a pool and last winter we left the solar
blanket underneath the black winter tarp. It's didn't lessen the ice at all.
The solar blanket just froze intot he ice. I'm in zone 6b and I use a stock
tank de-icer in the pond. I don't think the aquarium heater is going to do
it...

The de-icer worked great for me.
