7.4 to 7.6 is the sweet spot for saltwater pool pH.

Keep it there. Outside that range your chlorine generator stops working efficiently and your water can get cloudy or corrosive.

Saltwater pools tend to drift upward because the electrolysis process itself raises pH. You’ll test it more often than a standard chlorine pool. A good liquid pH decreaser (muriatic acid or sodium bisulfate) is your main tool. Add small amounts, wait a few hours, retest.

Don’t overthink it. Test twice a week, adjust as needed, and you’re done.
