What are the pool, what are the optimal levels of chlorine?
The water in the pool should be clear and without strong odors and tiles should feel clean and smooth, without slime or color. Regular maintenance is required to maintain above -ground and underground pools of clean and healthy. The pathogens that cause the disease must be removed or destroyed and the algae must be prevented for the water to be clean. Maintaining optimal levels of pH and chlorine is necessary to maintain the swimming pool safe. Ideally, the pool should always be around 2 ppm and the water must be tested regularly. Chlorine levels in the pool include as free chlorine that actively cleans the pool, and combined chlorine or chloramines that are formed when chlorine binds to contaminants and becomes inactive.
Chlorine levels in pools are generally maintained in two ways. First, they are slowed down by a chlorine tablet or a chlorine rod somewhere near a filter that distributes chlorine throughout the water. Different chlorine marks with slow release lasts for different time, so read carefullyy. When chlorine binds to contaminants, it becomes inactive. The water of the pool must therefore be "shocked" every week or two by adding a powered or liquid chlorine directly into the water. The chlorine used is burned by shock, which is then removed by the filter.
When the pool smells strongly chlorine or burns eyes or skin, many people believe it is due to high levels of chlorine, but in general it is not. A strong odor of chlorine is caused by excess chloramines in the pool. Chloramines are a compound that is formed when chlorine combines with ammonia in contaminants. It is inactive chlorine and should be removed shocking with active chlorine.
If the water in the pool causes burning eyes or skin or redness of the eyes, the cause is often too high or low pH. The pH of the pool should ideally be between 7.2 and 7.6. If the pH is too low, it can corrode the heating and filtering equipment and cover the walls. If it ispH too high, chlorine can be ineffective or inactive. PH can be reduced by acid and raised with soda ashes, although swimming pool owners should examine other reasons for changes in pH before attempting to modify.
