Your advice please, I’m panicking as the temperatures have nose-dived! My pool is at our second home in France. I have only just been able to return to it and the temperatures have plummeted: it is -1c (30f) this morning. I covered it end of Aug - with algae and a high Cya problem that I ran out of time to fix. Since then I know they have had some hot weather here during Sept. Should I just drain it down now below skimmers, add floaty things, protect pipes, filter, take pump indoors (that’s our normal routine) OR do I need to test and correct chemistry first? I have come back armed with the Taylor K-2006 thanks to advise on here! Thanks for any advice- I feel I’m racing against time!
