we have tried putting a tennis ball in the centre of our garden pond
to stop the water from freezing however, with the bad weather recently
this hadn't worked. Can anyone suggest an alternative?

Please explain the theory behind the tennis ball. TIA

Hi Tyrone,

The theory is that because the tennis ball is bobbing about all the
time the water is never still so it doesn't freeze - clearly this
hasn't worked though.
