To ensure that the pool water doesn't turn green whilst over-wintering, we cover the whole thing with black plastic. As long as absolutely no light gets through, the water will remain crystal clear. You may in fact see how clear it is through the hole (above).
The plastic is quite sturdy, but not enough to cope with the pack of dogs who somehow managed to get into the pool area.
They've torn a huge hole in one corner, and buggered-up the cover for next year.
We like our neighbour's dogs (even though they did kill our hens), but we would like them even more if they were kept under some control.
As with the horses previously, their own water seems to be in short supply, and I imagine they have come to drink the water that's gathered on top of the plastic cover.
We're not quite sure why the muddy footprints are there.
I think the replacement will cost about €40; not a huge amount. Should I ask him to compensate me? No point; he'd just walk away, he's had years of practice!
