Definitions for "Chloramines"
Combined chlorine products are formed by a reaction between nitrogen compounds often derived from bathers (think about it!). These chloramines are responsible for unpleasant odors and eye irritation. They can be broken down by raising the free chlorine level.
Undesirable, foul-smelling, body-irritating compounds formed when insufficient levels of free available chlorine react with ammonia and other nitrogen-containing compounds (swimmer and bather waste, fertilizer, perspiration, urine, etc.). Chloramines are still disinfectants but they are a much weaker, ineffective form of chlorine. Chloramines are removed by superchlorination or shock treating.
smelly organic by-products caused by using too little chlorine to keep a pool sanitized.
