Hi all! Just opened our pool yesterday and can't seem to find the Pool Math chart that I used all of last year. I can only find apps for cell phone etc. I have a laptop computer I use. I'm sure it's here but have looked for 20 mins so gave up & decided to ask. Tks! (I also wonder where all my info went to that described my pool at the bottom of my posts...
