What is the best resource for pool cleaning and maintenance?

Hi:) We have just inherited a beautiful gunnite above ground pool. The pool guy showed me very quickly and briefly how to use the filter machine (technical term? LOL) with the filter / wash / rinse waste parameters. I am very confused. We try to use the pool attached with suction to the skimmer and a long pipe, empty / poles. We scrubbed down yesterday first. Anyone have any tips or websites or books, I must read to stay with my pool? Thank you!

I always use this site. It has a swimming pool filter and contains good information about when replacing. http://findreplacementfilters.com/Store/Pool-Filters
