Just lately I encountered a blog post about goldline salt cell. I have no idea what salt cells are so I made a little research. Then I found out that salt water chlorination is possible and some pool handlers are already using this. Then I thought that salt water chlorinators are great invention. Moneywise it can save a lot for pool owners that use salt water instead of clean water.
I am not really well-versed in how pool are ran and maintained but I am sure that these kind of inventions can really help a lot!
