If chlorine is set low but readings are high, first, continue to adjust the chlorine output down as necessary. The chlorine that you measure in the pool is the leftover amount based on 1) how large a salt chlorinator you have, 2) what output setting you have it on, 3) how long a day it runs, and 4) the chlorine demand of the water. So in addition to lowering its output, you can also configure your setup for it to run less hours in the day. Once you find a balanced configuration, it is overall a good thing to not have to run your salt chlorinator very hard - you'll have much more power in reserve to allow you to deal with potential pool problems should they rise, and in the mean time less wear-and-tear should be occurring on the cell which should help it to last longer. You can also see this system's operational guide video, which provides more information about how this dynamic works.
