Can you add softened water to a pool?

Yes, softened water can technically be added to a pool, but it's not recommended because it can alter the pH balance and cause corrosion to pool equipment. Softened water has gone through a process called ion exchange, which removes certain minerals like calcium and magnesium. This can make the pool water more corrosive, damaging everything from ladders and pool covers to concrete surfaces around the pool.

Regular tap water is generally best for filling pools. If you do opt to use softened water, it is important to monitor and maintain the pH balance of your pool regularly to ensure it doesn't go out of range and cause damage to the pool equipment. Proper water chemistry and regular pool maintenance are crucial to keep your pool water healthy and safe for swimmers.
