Superchlorination, then, is narrow in purpose and, if necessary at all, critical in importance. Let's look at what it is we're getting rid of, why we need to superchlorinate, what happens and how to do it. Look at ammonia compounds of chlorine. These ammonia compounds of chlorine are also called chloramines, combined chlorine, the bad guys and even some non-printable names you're free to recall or imagine. Chloramines are lousy sanitizers and oxidizers, have an offensive chlorine-ish odor, irritate eyes and mucous membranes, don't do much to preclude algae, waste otherwise effective chlorine, and simply cost money.
Common sources are urine, sweat and decomposing organic matter.
The first, urine, can be minimized with good education and rules, handy bathrooms, time-out breaks, and maybe removal of the coffee machine. Ridicule sometimes helps, but is not recommended. The next two, perspiration and decomposition of everything from sluffed dead skin to leaves, dust and small dead animals, are even less preventable. Technically, there's both organic and inorganic ammonia - and the former is tougher to deal with than the latter. Let's keep it simple and lump them together.
