Between summer thunderstorms and hurricane season, rainfall can have an impact on pool water balance. The acid and contaminants in rainwater can cause the pool’s pH levels to rise, affecting the chemical balance of the water.
You can plan for rainfall by adding chemicals before and afterward to keep your water balanced. Here’s how:
Before the Storm
Being proactive and making sure the pool water is balanced before and during rainfall will help you keep the water in good shape throughout the season. Keep an eye on the weather in your area so you know when rain is on the way: When you’re expecting heavy rain, actively check the pH and chlorine levels of your pool and add additional chemicals accordingly.
After the Storm
Even after a mild rainstorm, pool chemicals can become diluted. In addition to your regular pool water maintenance routine, it’s especially important to check the water after rainfall. When the rain has stopped, check the pH level of the water first. If the pH is below 7.0, add more chlorine to the pool before you increase the pH, adding chlorine will typically increase the pH on its own.
If your chlorine level is low, you will need to add more chlorine until levels are back to normal.
Keeping track of your pool’s chemistry levels is difficult, especially after they’ve been altered by a rainstorm. You can keep an eye on your pool water status during the rain without even needing to grab your umbrella with the help of pHin! The pHin Smart Monitor sends real-time updates about your water status, taking over 1,000 measurements per week.
If the pH levels of your pool become unbalanced following the storm, pHin will send an alert in the app or via email. It’ll also provide easy-to-understand chemical dosing instructions to get the water balanced after the rain has passed.
After you make chemical updates, make sure your pool is running properly. Most rainstorms bring leaves and outside debris into the pool area and water, use a skimmer or vacuum to clean the pool before your next swim. Once the pool is clean, check the water level. If the water level is above normal, you’ll need to drain the water -- too much water in the pool will cause issues with the skimmer which can lead to water chemistry issues.
