Swimming pools blog

Would like a website(s) which can help make decisions on planning a new
pool.
Open questions I have include:
1) salt system vs chemical - pros and cons?
2) filter type pros and cons?
3) robot cleaner vs built in water jets that spray dirt to the main
drain?
4) any websites that give plans for raised flower beds / benches around
pools
5) any websites that help plan a backyard / pool, etc.
Thanks much.
