This is part of the ionic reaction and not an indicator of toxins. 2.Salt Limit: Do not exceed 5g of salt per use. Excess salt increases water conductivity, triggering automatic safety shut-off. If Unit Stops: Add fresh water or Replace with new water. 3. For best results, use as part of a regular relaxation routine. 4. Not intended to diagnose, treat, or prevent any medical conditions.
