Did you know algae could be a sign of a leak in your pool?

If your pool has persistent algae growth even after chemical treatments, you might be facing a deeper issue. Algae and pool leaks are more connected than they seem—because a leak can throw off your pool’s chemical balance, creating the perfect environment for algae to thrive.

🧪 Why do leaks encourage algae growth?

Leaks cause a constant loss of treated water. As water escapes, it alters chlorine, pH, and other chemical levels, creating instability. Algae love this imbalance and multiply quickly, affecting both the water’s appearance and its safety.

🔍 Warning signs of a possible leak

Before blaming your chemicals, look for these signs that could point to a hidden leak:

• Water level drops more than usual

• Algae always growing in the same areas

• Persistent wet spots around the pool perimeter

• Higher chemical usage with no visible results

These signs may be revealing a deeper issue—algae growth linked to water loss.

🧴 The bucket test: a simple method

Place a bucket filled with water on the first step of the pool. Mark the water level inside the bucket and the pool’s waterline. Wait 24 hours. If the pool water drops more than the water in the bucket, there’s likely a leak.

🛠️ A professional solution is key

Detecting a leak early not only helps control algae growth but also prevents structural damage. Professionals can perform hydraulic tests or use leak detection dye to pinpoint the issue and repair it properly.

The connection between algae and pool leaks is more common than you think. If treatments aren’t working and algae keep coming back, it’s time to find the root cause. Taking action early can save you headaches—and money.

Algae and leaks do more damage than you think. Don’t ignore the signs.
