My pool's been 94 for the last 4 days (

You're kidding!! ????

Also, is there any good reading book materials on swimming pool? The only one I came across which I liked but a bit too technical is "The Ultimate Guide to Pool Maintenance" 3rd edition.

Unfortunately, no. I have that particular book, and it has MANY serious errors. (So do all the others I have!)
