In general, it won’t cause any issues if you’ve added a bit more salt to your pool. Salt is a natural product that won’t harm a swimmer’s skin or hair, even if you’ve accidentally added more salt than your pool chlorinator manufacturer recommends.
However, remember that if the salinity levels reach 5,000 ppm or more, you risk corrupting the metal equipment in your pool, and your saltwater generator might not work correctly. If your swimming pool salt levels are too high, you’ll need to dilute your pool’s water by partially draining it and adding fresh water to bring the salt levels back down to an acceptable level.
