Rain and Pool care

Pools can be affected by heavy rainfall and storms but fortunately the adverse side effects can be counteracted using the right combination of HTH® Pool Care products.

Test your water
Heavy rains can dilute the chemicals you’ve added to your pool water. After a storm or lengthy rain, it’s always smart to double-check your water balance, stabilizer and sanitizer levels with an HTH® 6-Way Test Kit or box of HTH® 6-Way Test Strips to be sure your pool water is still adequately balanced, stabilized and sanitized.
Water Balance and Chemistry

Check the water balance and chemistry
Even rainwater has its own water chemistry, so a significant rain event could raise or lower your pool water’s pH and Total Alkalinity levels. To adjust your water balance parameters, don’t forget to check your stabilizer, pH and Total Alkalinity levels. You may need HTH® pH Minus, HTH® Alkalinity Plus, or HTH® pH-Plus® balancer to get your pool water back to its pristine, clear blue state.
Clean and Treat

Clean and Treat
Rainwater that washes or falls straight into the pool water or that falls off of tree branches can introduce algae and other contaminants into your pool. These contaminants can quickly use up your sanitizer. Adding an HTH® shock treatment after the rain has passed will break down the contaminants and keep your pool water clear for the next sunny day.
