How many bags of salt in 27 ft pool?

To determine how many bags of salt are needed for a 27-foot round pool, you first need to know the pool's volume. A 27-foot pool holds approximately 5,500 gallons of water. Most saltwater systems require around 30-50 pounds of salt per 1,000 gallons, so you would need about 165 to 275 pounds of salt total. If each bag is 40 pounds, you would need approximately 4 to 7 bags of salt.
