☀️ EXTREME HEAT = EXTRA POOL CARE! 💦
When it’s extra hot outside, your chlorine takes a beating! High temperatures and strong sunlight cause chlorine to burn off faster, while algae can grow quicker. 🦠
If you’re not adjusting your pool-care routine during a heat wave, you may find yourself fighting cloudy or green water.
Here are 3 things to check to keep your chlorine in fighting shape: 👇
1️⃣ Run Your Pump a Little Longer
On the hottest days, consider adding an extra hour or two of circulation. Moving water helps distribute your chemicals evenly and keeps your pool properly filtered.
If you have a variable-speed pump, longer periods of lower-speed circulation can be especially helpful during extreme heat.
2️⃣ Check Your Stabilizer (CYA)
Cyanuric acid (CYA), also called stabilizer or conditioner, helps protect your chlorine from being destroyed by the sun. ☀️
Without enough stabilizer, your chlorine can disappear VERY quickly on a bright, hot day.
For most traditional chlorine pools, we generally like to see CYA around 30–50 ppm. Saltwater pools may benefit from a somewhat higher level around 50-80 depending on the system.
⚠️ More isn’t always better! Too much CYA can make chlorine less effective, so test before adding stabilizer.
3️⃣ Shock in the Evening 🌙
If your pool needs shocked, evening is the best time to do it. Adding shock after the sun goes down gives the chlorine time to work without immediately being broken down by UV rays.
During stretches of extreme heat and heavy swimming, keep an extra-close eye on your chlorine level and water clarity. Test more frequently and shock as needed rather than waiting until the water starts turning cloudy or green.
