I swim 3 3/4 miles several times a week and cannot do this workout in a saline pool. The salt causes my skin nerves to feel pulled, and I experience bronchial problems and cough up salt for days. It may interest some to know the USOC does not sanction saline use. Saline generated chlorine is unstable and is hard to balance with pH - this can weaken antibacterial quality of chlorine. Saline is also salt and highly corrosive to pool mechanics and decks. Just think it's important to know the facts before anyone falls for the salt sales pitch.
