If I had to do it all over I'd go with Copper Silver Ionization system for the pool. Sadly that's only a very very very small part of the pool expense. The pool itself and pumps are what use to cost us the most. You only do that stuff once every 5-10 years but it's so expensive you may as well be saving $100/month extra to cover it.
IF YOU FIND ANY MISTAKES IN MY WORK...Please consider that they are there for a purpose. I try to please everyone and there is always someone looking for mistakes!
