Hi. Here are the readings:
I think I lose around 1 ppm of FC per day (although I have not done the FC loss test on the site here).
I am going on vacation for 7 days and no one will be using the pool. Before I leave, should I up the FC to 16, on the assumption that it will be back down to approximately 9 when I return?
What do people typically do when they go on vacation? Thanks
