Ooh I presumed it was a US forum as most of the intro posts I looked at were from the US .
Well we've had much less rain that we thought we were going to get but the colour of the slate has really come out now as it's less dusty and it's very pretty. My husband has been trying to de-chlorinate the water by spraying it from the wateringcan to a large bucket and back to the watering can and spraying over into the pond - I think I read that's a good way to disperse it but with a hose which was can't currently use as experiencing a hose pipe ban.
It's over a third full now. Hoping for more rain (don't say that often!).
