If you are getting a low reading of chlorine in your above ground pool, you should add the appropriate amount of chlorine to get it back to the correct level. This is important to keep your pool running at maximum abilities.
If the chlorine level is correctly maintained this should not be a problem.
Cl is an abbreviation for "chlorine" you should check free chlorine and total chlorine for comparison.
Chlorine level should stay between 1.0 and 3.0 parts per million (ppm) to maintain a healthy pool.
You only need to shock the pool if there is visible algae, or if the ppm of total chlorine is higher than the ppm of free chlorine. Generally, a level of 2-4 ppm chlorine is all you need to keep your pool sanitary. Let the level drop to that on its own, or use sodium thiosulfate to drop it quickly if you notice itchy skin from excessive chlorine.
You add water to the pool
Chlorine level in an 18' above ground pool should be between 2 and 4.
Use stabilized chlorine only so long as stabilizer level (cyanuric acid level) in pool is within the recommended range of 50-80ppm.
A few days. You will probably be able to use the pool when the level gets to about 5.0 ppm 1) you should know the difference between residual chlorine and Free chlorine 2) Chlorine lost depend on size of you pool and temperature 3) circulation of water , temperature & size of pool will increase chlorine lost

You should not re-enter the pool until the chlorine level is 3ppm or less on your test strip, however long that takes. Chlorine is a known carcinogen and high chlorine levels are linked to many respiratory diseases.
Generally if chlorine level is maintained between 1-3ppm you should not smell chlorine. As the level rises it becomes noticable, however most complaints about chlorine smell are due to chloramines (even in a clear & clean pool), chlorine molecules which are bound by swimmer wastes and/or bacteria introduced to the pool. This problem can be confirmed by a reputable pool shop by testing your water. Fix it by oxidising your pool regularly during the swimming season and let the pool breathe by removing the cover for the following hour or so.
