How to Clean Your Pool After a Storm in Baton Rouge

If you live in Baton Rouge, you already know the drill — and if you’re searching for how to clean your pool after a storm, you’re in the right place. Storm season rolls around, and before you know it, your pool has gone from a backyard paradise to something that looks like a bayou. Between the wind-blown debris, the flooding rains, and the knocked-out power, getting your pool back in shape is no small task — but it’s something you need to tackle quickly.

Whether you just came through a tropical storm, a pop-up summer thunderstorm, or a full-blown hurricane, this guide walks you through exactly what to do to get your pool clean, balanced, and swim-ready again. We’ve helped hundreds of Baton Rouge homeowners restore their pools after storms, and we’re sharing everything we know right here. This guide covers everything you need to know about how to clean your pool after a storm.

Before You Touch Anything: Safety First

We know you want to get your pool back up and running as fast as possible — but rushing in before it’s safe can cause serious harm. Before you start cleaning:

• Wait for the all-clear from local authorities. Don’t go outside while wind or lightning is still present.
• Check for downed power lines near your pool equipment pad. If you see any, call Entergy Louisiana immediately and keep everyone away until it’s resolved.
• Do not run your pool pump or any electrical pool equipment until you’ve inspected it for water intrusion or damage.
• If your pool overflowed or flooded significantly, treat the water as contaminated until you’ve tested and treated it.

Step 1: How to Clean Your Pool After a Storm Starts With Debris Removal

The first step to clean your pool after a storm is removing all debris. Storms love to throw sticks, leaves, roofing materials, lawn furniture, and all kinds of other surprises into your pool. The faster you get this stuff out, the better — organic debris breaks down and rapidly throws off your water chemistry.

• Use a leaf net or skimmer to scoop out large debris. Work from the shallow end toward the main drain.
• Empty your skimmer and pump baskets — they’re almost certainly full. A clogged basket means poor circulation, which makes everything worse.
• Check your pool deck, too. Any debris sitting on the deck can wash back in, especially if it rains again.

Pro tip: Don’t vacuum the pool yet. Get all the debris you can out with a net first. Running your vacuum over heavy leaf matter can clog your lines and strain your equipment.

Step 2: Inspect and Clean Your Filter

Your filter is working overtime after a storm, and it needs some attention. The type of filter you have determines the cleaning steps:

Sand Filter

Run a full backwash cycle until the water runs clear in your sight glass. If your pool was extremely dirty, you may need to run two or three cycles.

Cartridge Filter

Remove the cartridge and rinse it thoroughly with a garden hose. If it looks worn, discolored, or damaged, this is a good time to replace it — a compromised filter won’t do its job when you need it most.

DE (Diatomaceous Earth) Filter

Backwash the filter and recharge with fresh DE powder. If the pool water was particularly dirty or full of fine debris, consider a full tear-down and cleaning of the DE grids.

Not sure which filter type you have or how to handle it? Contact our team at PEC — we can walk you through it or come out and take care of it for you.

Step 3: Balancing Water Chemistry After a Storm

When cleaning your pool after a storm, water chemistry is the most critical step, and it’s one a lot of homeowners skip straight past. After a storm, your pool water has absorbed rain, runoff, debris, dirt, and who knows what else. All of that messes with your water chemistry — sometimes drastically.

Test for all of the following:

• pH (target range: 7.4–7.6)
• Total Alkalinity (target: 80–120 ppm)
• Calcium Hardness (target: 200–400 ppm)
• Cyanuric Acid / Stabilizer (target: 30–50 ppm for outdoor pools)
• Free Chlorine (target: 1–3 ppm normally; higher for shocking)
• TDS (Total Dissolved Solids) — especially important if flooding brought in significant outside water

Louisiana’s intense summer rains can dump a lot of water into your pool very quickly, diluting your chemicals and throwing everything off. Don’t skip the test kit — treating without knowing your baseline is just guessing.

Step 4: Shock Your Pool

Even if your chlorine reads in a normal range, shock your pool after any major storm. Stormwater introduces bacteria, algae spores, debris, and contaminants that regular chlorine levels won’t fully address right away.

Here’s what to do:

• Use a calcium hypochlorite or sodium dichloro shock product at a dose appropriate for your pool size (typically 1 lb per 10,000 gallons for a standard shock; go heavier if the water looks green or cloudy).
• Shock at dusk or nighttime — UV rays break down chlorine quickly in Louisiana’s sun, and you want it to work overnight.
• Run your pump while shocking to distribute the chemical evenly.
• Keep the pool off-limits for at least 8 hours after shocking, or until chlorine levels drop back to 1–3 ppm.

If your pool water is green, cloudy, or has a strong odor, you may need to super-chlorinate — sometimes multiple times over a few days. Algae after a storm is very common in South Louisiana’s heat, and it can get away from you fast if you don’t stay on top of it.

Step 5: Vacuum and Brush the Pool to Clean Up After a Storm

Once the water has circulated and the big stuff is out, it’s time to vacuum. Set your multiport valve to “Waste” (not “Filter”) if your pool has a lot of sediment on the bottom — this bypasses the filter and sends the dirty water straight out, preventing your filter from getting overwhelmed.

Then brush the walls, steps, and any areas where algae might be starting to grow. Getting the algae spores into suspension makes it easier for your chemicals to kill them.

After vacuuming:

• Backwash or clean your filter again — it just did a lot of work.
• Run your pump for at least 24 hours continuously to keep circulation going.
• Re-test your chemistry after 12–24 hours and make any final adjustments.

Step 6: Inspect Your Pool Equipment After a Storm

Storms can damage more than just the water. Before you declare your pool fully restored, walk your equipment pad and take a close look at everything:

• Pump and motor: Listen for unusual noises when running. Check for visible cracks or water intrusion in the motor housing.
• Filter housing: Look for cracks, damaged O-rings, or broken clamps.
• Pool heater: If you have a gas heater, make sure the pilot and burner chamber are dry before firing it back up.
• Automation systems and timers: Check that they’re still programmed correctly — power outages can reset them.
• Pool lights and electrical: If any lights or junction boxes show signs of water intrusion or damage, don’t use them until a licensed electrician or pool tech has inspected them.
• Decking and coping: Look for cracks, shifting, or lifted sections that could be a trip hazard.

If something looks off, don’t ignore it. A small equipment issue caught now is a much cheaper fix than a full pump replacement down the road.

When to Call a Pool Professional

We believe in empowering homeowners to handle what they can on their own — but there are times when calling in a pro just makes sense. Reach out to PEC Pool Maintenance division if:

• Your pool water is dark green or black and hasn’t responded to multiple shock treatments.
• You suspect structural damage to the pool shell, deck, or coping.
• Your pump, filter, or heater is making strange noises or won’t start.
• You’ve lost power and aren’t sure it’s safe to restart your equipment.
• You just don’t want to deal with it — and that’s completely valid.

Prep Your Pool Before the Next Storm Hits

Living in Louisiana means storm season is just part of life. Here are a few things you can do before a storm rolls in to make the cleanup easier afterward:

• Lower the water level slightly before a big storm — about 6 inches below the skimmer. This gives room for rainfall without overflow.
• Do NOT drain the pool completely. An empty pool can pop out of the ground in saturated soil. This is a real risk in South Louisiana.
• Remove or anchor loose items around the pool — chairs, toys, pots, anything that could become a projectile or end up in the water.
• Turn off your pool equipment at the breaker. Don’t just use the timer or automation — cut power at the source.
• If a major hurricane is expected, consider a pre-storm shock and algaecide treatment to give the water a fighting chance.
