Oversalting will not harm your Pool, but will lead to salty tasting water. For some, thisis not undesirable as it will more closely match our bodies natural salinity level, making it morecomfortable to swim in. If it is too excessive (over 6,000 ppm), you can sustain corrosion damageto metallic equipment such as stainless steel handrails, ladders and filters, light rings, or copperheat exchangers. To reduce the salt level, dilution is the solution. Drain some water and refill withfresh water.
