A comment on the day.

All  @£$%^&*  day!
There seems to be a slight leak in the waterfall to the pond. Daft thing is I can NEVER locate it. Every time I lift ANY section it's bone dry beneath.
However - point is I used to have a hose on virtually a drip rate to maintain level. Then I put the timer in to run about 5-10 mins on the hour. This reduced it to a state where the trickle feed was no longer necessary but still the occasional top up, maybe every month.
NOT of late, it's looked this full since I forget when.
But you can see why I/we haven't stirred far again.
