I find that I need to add more salt to my pool. I thought the salt was only lost by splash out or refiiling. But my salt level has appearently dropped from 3400 to 2700ppm. Some of the drop could perhaps be attributed to the heavy rains over the past month.

My neighbor (who also has a SWG) says it is normal to add salt periodically. He says the salt is consumed by the chlorine manufacturing process and as the chlorine is used (sanitizing) the pool there is not enough "chloride" left to recombine into salt - which is why the PH increases and necessitates adding the muratic acid. Then you need to add more salt for the process to continue. Does any of this make sense?

Thanks.
