What to do during/after Stormy Weather
We all know we need this rain, but being a pool owner can give you mixed feelings about this type of weather. A little drizzle every now and then will barely affect your perfectly balanced and blue pool. But ALOT of rain can really mess with the clarity and the chemistry. So, what do you do?

When a big Texas thunderstorm rolls through, one of the first questions we hear is:
“What do I need to add to my pool now?”
Wind blows in leaves, pollen, dust, and organic debris. Runoff can introduce dirt, fertilizers, and other contaminants. More swimmers often follow the storm, adding even more demand on your sanitizer.
Your pool suddenly has a lot more work to do.
The Easy Fix
After heavy rain, it’s perfectly fine to add a dose of liquid chlorine (shock)—especially if you know your pool has taken on a heavy organic load.
When in doubt, SHOCK IT OUT.
Treat 1 Gallon of Liquid Shock per 10,000 gallons of water
Then let your pool circulate, clean out any debris.
If storms continue to roll through, don’t chase every test result between rain events. Wait until the weather settles.
Sometimes all your pool needs is a little chlorine.
Test and rebalance later.
Adding products without knowing your water chemistry can create new problems while trying to solve the old ones, but I’m sure many of you know what Leslie at La Vernia Pool & Spa is going to tell you after a rain!!
The most common occurrences are
Low Chlorine
High pH
Low Alkalinity
The WHY will be explained in the next installment.
Keeping the chlorine high is a temporary fix until getting back in balance.
Our Recommendation
The best thing you can do after a major storm is remove debris, empty your skimmer baskets, brush the pool if needed, run your equipment, and add liquid shock as you see fit. Especially, if you know your pool and your routine.
Bring us a fresh water sample for a free professional water test at you earliest convenience. We’ll map out a treatment plan to get you back in balance.
For example:
Correct alkalinity first and add chlorine. Lower pH in the following days.
(Correcting both Alkalinity and pH at the same time is never recommended.)
That’s how you spend less money on chemicals—and more time enjoying your pool.
Because the easy fix treats the symptoms.
Understanding your water solves the problem.
