Chemistry is the study of matter and energy at the scale of atoms and molecules. As the most all-embracing discipline there is, it should be at the top of everyone’s list of must-learn subjects. Unfortunately, chemistry has an undeserved reputation for difficulty and abstraction. Any subject that encompasses as many components as chemistry is going to appear complex. The beauty of delving into the study of chemistry is the discovery of how organized, logical, consistent, and powerfully predictive it becomes—if properly presented.

Notes:
The chemistry for a salt water pool is slightly different from a normal pool. Since the salt system is generating chlorine constantly the Sanitizer level is very stable. You will rarely need to shock a salt pool.
The chlorine level will be high also since it is constantly generating it, but it is safe at a high level. The pH will also drift high since the Hydrogen gas the cell produces leaves the water, the remaining Hydroxide will raise the Ph.
