Why Is My Pool Green?! Common Causes & How to Fix It Fast in Phoenix, AZ

Picture this: It’s a scorching summer day in Phoenix, the sun is blazing, and you’re ready to take a refreshing dip in your crystal-clear pool. You step outside, towel in hand, only to find… A SWAMP. Your once-gorgeous oasis has turned into a scene straight out of a horror movie, complete with murky green water and an eerie vibe that screams, “DO NOT ENTER.”

Take a deep breath—Triton Pools has seen it all, and we’re here to save the day (and your pool). If your backyard retreat is looking more like a pond than a paradise, here’s why—and what to do about it.

1. Algae: The Uninvited Guest

Let’s get straight to it—if your pool is green, algae is the culprit. Algae spores are like that one neighbor who always shows up unannounced. They float in the air, hitch rides on swimsuits, and love to settle into pools that aren’t properly maintained. Once they get comfortable, they spread FAST, turning your pool water into a green, slimy mess.

How to Evict the Algae Squad:

✅ Shock the pool: Not with bad news—just with a heavy dose of chlorine! Super-chlorination kills algae and restores water clarity.
✅ Brush it off: Grab a pool brush and scrub down the walls, floor, and steps to break up the algae colonies.
✅ Call in the pros: If the green keeps coming back, give Triton Pools a call at (623) 259-6492—we’ll kick algae to the curb for good.

2. “I Forgot to Add Chemicals” Syndrome

Life gets busy, and sometimes, pool maintenance slips through the cracks. Maybe you missed a week of chlorine, or the pH levels got out of whack. Arizona’s hot sun makes this even worse—high temps burn off chlorine quickly, leaving your pool vulnerable to algae and bacteria.

Fast Fix:

✔️ Test your water with a pool testing kit to check chlorine, pH, and alkalinity levels.
✔️ Adjust chemicals as needed—chlorine should be between 1-3 ppm, and pH between 7.2-7.6.
✔️ Feeling overwhelmed? Call (623) 259-6492, and we’ll handle the chemical balancing for you.

3. Your Pool Filter is on Strike

Your filter is like your pool’s kidney—it removes dirt, debris, and bacteria. If it’s not working properly, your pool water can go from clear to cloudy to swamp monster green in no time. Common filter issues include:

🚨 Clogged filters (especially in monsoon season)
🚨 Broken filter components
🚨 Not running the pump long enough

Quick Fixes:

🔹 Clean or replace your pool filter. (Cartridge filters should be cleaned monthly, sand filters backwashed, and DE filters recharged.)
🔹 Run your pump at least 8-12 hours a day in the summer—Phoenix heat demands it!
🔹 If your filter is beyond repair, Triton Pools can replace it—just call (623) 259-6492!

4. Surprise! There’s Phosphates in Your Pool

Phosphates are like a buffet for algae—they feed the green menace and help it grow. Common sources include leaves, dirt, fertilizers, and even some tap water.

Solution:

✅ Use a phosphate remover if levels are high.
✅ Keep leaves and debris out of the pool with a skimmer or pool cover.
✅ Schedule regular maintenance with Triton Pools at (623) 259-6492, and we’ll keep your pool algae-free.

5. Monsoon Season Madness

Arizona’s monsoon season brings dust storms, rain, and debris—all of which can wreak havoc on your pool’s chemistry. If your pool turns green after a storm, it’s time for a deep clean and chemical reset.

What to Do After a Storm:

✔️ Skim out debris and vacuum the pool.
✔️ Shock the water to kill bacteria and algae spores.
✔️ Run the filter non-stop for 24 hours to clear out contaminants.
✔️ Need post-monsoon pool rescue? Call Triton Pools at (623) 259-6492—we’ll handle the cleanup!
