POOL TIPS

Why is my swimming pool green?

As a pool owner, nothing beats the sight of clear, sparkling water on a sunny day. But what happens when you wake up to a green swimming pool? Whether you’ve got a small backyard pool or a larger inground setup, a green pool can be frustrating and worrisome. If you’ve ever found yourself asking, “Why is my pool green?” you’re not alone!

Why Is My Pool Green?

A green pool is usually a sign that something is off in your pool’s maintenance routine. Let’s dive into the most common reasons your pool might turn that dreaded shade of green—and how you can fix it!

Algae Growth
Algae is the most frequent culprit behind green pool water. If your water circulation is poor or your chemicals are off balance, algae can start to bloom, quickly turning your swimming pool a greenish hue. Regular pool maintenance, including checking and balancing your pool’s chemicals, is the best way to prevent algae growth.

Pollen in the Pool
In areas with heavy pollen, like Austin, TX, pollen can find its way into your swimming pool. The yellow color of pollen, when mixed with blue pool water, can create a green appearance. An inefficient filtration system can recirculate this pollen, making the problem worse.

Faulty Pool Pump
If your pool pump breaks or isn’t working correctly, water circulation will suffer, leading to algae growth and other problems. Without proper circulation, your pool water can quickly turn green. If this happens, it’s crucial to repair or replace the pump as soon as possible.

Bad or Improperly Maintained Filter
Your swimming pool filter is one of the most important tools in keeping your water clean and clear. It works by removing debris, dirt, and other particles that can make your pool cloudy or green. However, if your filter isn’t cleaned regularly or it’s not running long enough each day, it may not be doing its job properly. This can lead to a buildup of debris and algae, which turns your pool water green.

Using the wrong type of filter for your pool can also cause problems. Different filters—whether it’s a sand, cartridge, or D.E. filter—are suited for different pool setups. If your filter is undersized or not working effectively for your specific pool, it can struggle to keep the water clean. A professional pool filter service can help you choose the right filter and ensure its maintained properly, keeping your pool water crystal clear year-round.
