A backyard swimming pool split diagonally to show a before-and-after effect: the left side is green with algae, while the right side is clear and blue. Two women and a small dog are seen near the clean side of the pool, under a bright sky.

There’s nothing worse than walking out to enjoy your pool… and finding that it looks more like a swamp than a swimming hole. If your pool keeps turning green in San Angelo, you’re not alone — and there’s a reason why it’s happening.

Let’s break down what causes it, how to fix it, and what you can do to keep your pool crystal clear all year long.


🌿 What Causes a Green Pool?

Green pool water is almost always the result of algae growth, which thrives in warm, unbalanced, or stagnant water. Here’s what makes it worse in San Angelo:

  • Extreme heat (especially late spring to early fall)
  • High calcium and hard water
  • Dust and pollen from West Texas windstorms
  • Missed cleanings or poor circulation
  • Unbalanced chlorine levels
  • Leaves and organic debris breaking down in the water

🧪 Algae can start forming in less than 24 hours if your chlorine level drops too low.


💸 How Much Does Green Pool Cleanup Cost?

Green pool cleanups typically cost between $150 and $300+, depending on the severity of the algae bloom, the condition of your water, and how long it’s been sitting.
