Why is My Pool Green?

swimming pool with green pool water

Imagine stepping out into your backyard for a refreshing swim on a hot day, only to be greeted by a green pool. This frustrating problem typically indicates there’s an issue with your pool’s regular maintenance routine. However, there’s no need to panic; you can rest assured that this unsightly problem can be corrected.

Why the Water in Your Pool Is Green

One major reason why your water may take on this ghastly hue is from algae growth.

This occurs when your pool isn’t skimmed, brushed, and vacuumed frequently enough.

Green algae may also be the result of the water’s chemical levels not being balanced. Insufficient chlorine levels or an imbalance of pH and alkaline levels create an environment highly conducive to this aquatic plant’s growth. When it’s left unchecked, algae can flourish, overtake your pool, and even turn the water green.

Exploring the Factors Contributing to Algae Growth

Algae will thrive if there are:

  • Warm and sunny conditions where your swimming pool’s warm water reflects the sun’s rays.
  • Areas with stagnant water where your pool’s water can’t circulate and isn’t properly filtered.
  • Leaves, debris, and other organic matter in your pool. These provide the nutrients that algae live off of. Therefore, regular removal of these materials is essential to maintaining a clear, healthy, and algae-free swimming pool.
  • High phosphates levels and nitrates in the water. This leads to decreased levels of oxygen, and it can also encourage algae blooms that are capable of hurting both people and animals.

However, regular testing and appropriate chemical treatments can help control these levels.

  • Chlorine levels drop and the pH begins to rise.

Common Mistakes and Misconceptions

One of the most common mistakes people make is to solely depend on chlorine. While it’s an essential sanitizer for your pool, you can’t rely on it to be the only tool in your kit when it comes to care and upkeep. A weekly dose of an algae inhibitor or suppressant goes a long way. You’ll still need to stay on top of all of your regular pool maintenance routines throughout the summer.

Another common mistake is skipping water testing. Regularly checking the chemical makeup and then adjusting the levels as needed is vital for maintaining a clean pool with clear water.

Finally, owners shouldn’t underestimate the significance of having a proper filtration system. This plays a significant role in removing organic particles from the water, thereby preventing green algae from invading your pool.

Steps to Clear a Green Pool

Preventing algae and the green water it creates is important, but what if you already have this problem? How can you get rid of it?

The first step is to go back to the basics and check your water’s pH chemical levels and adjust them accordingly. Next, you can shock the pool with a high dose of chlorine; this will help eliminate algae and keep your water clean and clear. Use an algaecide that is appropriate for your pool type. When you have an active algae bloom, an algaecide that contains copper can be most effective. Then it’s time to thoroughly brush the walls and vacuum the floor to remove any debris that may lead to continued algae growth. You can also improve the water’s circulation and filtration by cleaning or backwashing your filters so they are completely dirt-free and operating at peak performance levels. Throughout the entire season, you’ll want to continue to monitor and maintain a proper pH water balance.

Be Proactive

Understanding the causes of green pool water and taking proactive steps to both prevent and correct them will give you a clear sparkling pool that invites everyone to come in for a swim. Prioritizing regular maintenance, ensuring proper water and chemical balances, and using effective filtration systems can help prevent algae growth, keeping your pool clean and refreshed. Be sure to remain vigilant, regularly test your water, and commit to immediately taking action at the first sign of any discoloration. Following these steps will give you a picture-perfect pool that provides endless joy for you, your family, and your guests. Dive in and start enjoying a crystal-clear pool today!
