Frozen pond

Hi all
Having seen upto 2 inches (60mm) of ice on ponds over the last week, its time for all pond owners with fish to be aware of the dangers of a frozen pond. If ice forms over the entire surface of the pond there is a real possibility that fish will die. This is because
1.the ice blocks oxygen entering the pond (fish need oxygen)
2. rotting debris etc below the ice cause gases produced to be trapped below the ice.

So we need to keep an area of the pond surface free of ice. Thermostatically controlled pond heaters are a extremely cost effective method of maintaining an area free of ice.
Alternatively running a stream or waterfall will also work once the water continues running constantly.

It is probably better to use a small oxygenator pump to keep an area clear of ice.
