If you’re wondering how to clean a green swimming pool, or you’re searching for the best way to get clear water again, you’re in the right place

Why Does a Swimming Pool Turn Green?

The most common cause is algae growth, triggered by:

• Low chlorine levels
• Poor water circulation
• Dirty or clogged filters
• Imbalanced pH and alkalinity
• Heat and sunlight exposure

How to Clean a Green Swimming Pool: Step-by-Step

If you’re searching for how to get a green swimming pool from green to clear, follow these proven steps:

1. Inspect Your Pool Equipment

Start by making sure your filter and pump are working properly. A malfunctioning system won’t be able to fight algae effectively.

2. Brush the Pool Walls and Floor

Algae cling to surfaces. Use a stiff pool brush to scrub every inch of the pool: Walls, sides, floor, steps, and even ladders. This breaks up the algae and prepares it for chemical treatment.

3. Shock the Pool with Chlorine

Use a chlorine shock treatment, ideally at double or triple the normal dose. This is one of the fastest ways to clean green algae from your swimming pool and kill bacteria. Make sure to follow safety instructions.

4. Run Your Filter Continuously

Let your pool filter run nonstop for at least 24 to 48 hours. This helps remove dead algae and restore water clarity. Clean or backwash the filter often during this process.

5. Vacuum the Pool

Once the algae settle at the bottom, manually vacuum your pool. Avoid automatic cleaners—they can stir up debris and spread algae around instead of removing it.

How to Clear Green Water in a Swimming Pool Fast

Sometimes, even after following these steps, the pool still looks bad, especially if the surface is stained or the algae problem is advanced. That’s when you need a deeper solution: an Acid Wash.

An Acid Wash is a specialized service that removes embedded algae, calcium buildup, and stains from the pool’s plaster or concrete surface. It’s often the fastest and most effective way to clear up a green swimming pool and restore its original appearance.

When to Call a Professional Pool Service

If you’ve tried to clean your green pool yourself and it still looks murky or stained, it’s time to call a local expert. DIY methods don’t always work for severe cases, and using the wrong chemicals can make things worse.
