Can you tell what’s hap­pen­ing in this photo?

Hint: It has to do with pH (answer is below.)

The pH level of your pool is crit­i­cal and you should be test­ing it weekly. The basic rule of thumb is that a pH level of 7.0 is neu­tral, any lower is acidic and any higher is alkaline—you should ide­ally keep your swim­ming pool between 7.2 and 7.6.

Why is this so impor­tant? A cou­ple of rea­sons. Swim­mer com­fort is related to the pH of the water. A swimmer’s body and eyes have a pH between 7.2 and 7.8. If pool water isn’t kept in this range then swim­mers will start to feel irri­ta­tion of their eyes and skin.

If you don’t keep the pH at the cor­rect level, the acid­ity can eat away at the beau­ti­ful pool sur­face, mak­ing it rough—or worse. This photo shows a once-gorgeous aggre­gate sur­face. While the sur­face itself is durable in low pH water, the binder or cement isn’t—and you can see how the water has eaten it away.
