Launch the pHin Mobile App and follow the instructions to set up your pHin. When you first put pHin in the water, you will receive a “testing water” message. Wait 30 minutes for the results. Make sure that you receive the blue “Perfectly Balanced” message before you jump in.
If your water is not perfectly balanced, don’t jump in. Bring your pool or hot tub into balance first for your and your loved ones’ health and safety.
