Your pool might look okay, but water can turn unsafe without you realizing it. Here are 5 warning signs that something’s not right — and it might be time to take action.
1. Strong chlorine smell
Many people think a strong smell means there’s too much chlorine. But actually, it’s the opposite. That smell comes from chloramines, which form when chlorine mixes with sweat, body oils, or urine. They can cause red eyes, itchy skin, and that harsh smell in the air.

2. Cloudy or dull water
Your pool water should always look clean and clear. If it’s looking cloudy or murky, it might be because of unbalanced chemicals, a broken or dirty filter, algae starting to grow, or not enough sanitizer (like chlorine).

3. Eyes and skin feel irritated
If your eyes burn or your skin feels itchy after swimming, the water is likely off balance. This could be caused by high pH levels or a build-up of chloramines — both of which mean the pool needs attention.

4. Algae on surfaces
Slimy green, yellow, or black patches on the walls or floor of your pool are a sign of algae. Not only does it look bad, but it makes surfaces slippery and unsafe.

5. No chlorine reading
If you test the water and there’s no chlorine, stop right there. A pool with no chlorine can quickly become a breeding ground for bacteria. It’s not safe to swim until it's fixed.
