Electric deicer for my pond?
We have a 1200 gallon pond with rubber liner, depth varies from 12" to 20". We have had goldfish and green frogs for the last several years, and they live in it year round (as do a corkscrew rush and water lilies).
I had previously kept the pond clean by cleaning accumulation in the spring, then with regular scooping and partial water changes throughout the summer. In the winter, I've tried to keep a hole open with a pot of hot water.
This past spring I bought a Lifegard Aquatics All-In-One and was very pleased with the results. The water is clean, and we enjoy the fountain feature (it's a bio and mechanical filter, uv filter and fountain). The pond has never looked so good.
I am now phasing out (decreasing the usage hours of) the filter and fountain to prepare for taking it out for the winter. I think that I should now buy an electric deicer so that I can keep a nice hole in the ice (we put in a new electrical outlet for the pond pump, so now can plug one in instead of my lugging hot pots of water out to the pond! Yay!).
Does anyone have any brand/ model recommendations?
Also, I'm allowing some maple leaves to sink to the bottom of the pond in the deepest area so the frogs can have a place to hibernate. That never was a problem in previous years, but the pond bottom has been so clean all year that I feel I should do something. Any suggestions or other ideas?
