Maintaining total alkalinity in the appropriate range is crucial for maintaining proper water chemistry. Total alkalinity acts as a buffer against changes in pH; the ideal range for total alkalinity is 80-120ppm. Insufficient alkalinity can result in eye irritation, damaged plaster, and even corrosion of pool equipment, impacting efficiency. Excessive alkalinity can lead to imbalanced pH and increased calcium hardness, creating scaling in the pool. Pool Solutions Swimming Pool Total Water Alkalinity Plus Increaser 25LB (P36025DE) helps sustain balanced water chemistry.
