I tried to search before posting this question but was not successful in finding anything - could mean I am not a good searcher so please direct me if there is an existing thread.

My question is: after reading alot on the PoolSolutions website it appears that much of the 'conventional' wisdow is at least partially flawed, with that in mind, are the books by Robert Lowry worth getting? I am referring to the manuals that are available at NSPF detailing water chemistry, testing and equipment troubleshooting.

Thank you
