We purchased a house with a pool and my husband and I were spending a lot of money hiring professional help to maintain nice and clean. Some people would tell us how easy it is to take care of it yourself while others said it was very time consuming and expensive. I decided to buy a book that would explain the basics and this book is it.This book along with 'I Love My Pool: The Perfect Pool in Five Easy Steps' has helped my husband and I understand how pools work, what kind of chemicals we need, how the filtering system works, etc., and now we are saving a lot of money taking care of the pool ourselves.
