Pool opening, after its long winter's hibernation, is fraught with danger.
This last winter I went against most advice and covered the pool with a large sheet of heavy duty black plastic, which I cut to fit its shape; I left no central drainage hole.
When we opened up on Sunday, the water beneath was sparkling clear. Then (being lazy) I allowed all the cover's gathered dirty water to go into the pool, on the principle that any muck would go straight to the bottom, and could be vacuumed up very easily. Well, it sounded right.
We still have all the surrounding flagstones (the beach) to scrub clean, and the robot still has the bottom to vacuum, but otherwise everything has gone according to plan, and it looks almost ready to use.
No mice in the electrics, the pump is working, and Lady Magnon's busy knitting me a new pair of trunks as I write.
I've just been to look, and the water is 20 C. What larks!
