Have you noticed a strange tint to your pool water or maybe your hair has a greenish hue after swimming?
These are telltale signs that copper might be lurking in your pool. Not only can copper cause discoloration, but it can also stain your pool surfaces and even affect your swimmers’ health.
So, how do you remove copper from swimming pool water? Well, the best methods include using metal sequestrants, applying pool flocculants, partially draining and refilling the pool, and upgrading your water filtration system.
Also, regular testing and proper chemical balance will help keep copper levels in check and your pool sparkling clean.
Let’s dive into why copper builds up in pool water and, most importantly, how to get rid of it!
Understanding Copper Contamination
Copper contamination in pools is more common than you might think. While it’s natural to expect debris or algae, metal in the water is often an overlooked issue.
Sources of Copper in Pool Water
Copper can enter your pool from several unsuspecting sources:
- Old plumbing systems: If your home or pool system uses copper pipes, small amounts of copper can leach into the water over time.
- Copper-based algaecides: Some algaecides contain copper as an active ingredient to kill off algae, but they can leave traces behind in your pool.
- Natural sources: If your pool is filled with well water, there’s a chance that it contains copper due to mineral deposits underground.
- Corrosion of pool equipment: Pool heaters or equipment with copper components can corrode, especially when your pool’s pH or chemical balance is off, leading to copper entering the water.
Effects of Excess Copper
Excess copper in your pool water can lead to a range of frustrating and potentially harmful issues, both for your pool and for the people using it:
- Staining: Copper can cause unsightly blue-green stains on your pool surfaces, ladders, and fixtures.
- Water discoloration: A green or blue tint to your pool water might look cool, but it’s a sign of too much copper.
- Green hair: Copper reacts with chlorine, and when swimmers with blonde or light-colored hair dive in, they may emerge with green-tinted hair.
- Health concerns: Prolonged exposure to high copper levels can be harmful, potentially causing skin irritation.
Testing for Copper in Pool Water
Before you can remove copper, you need to confirm its presence. Luckily, testing for metals in your pool water is easy with at-home kits.
Here’s how to do it:
- Use a liquid- or strip-based test kit specifically designed for detecting metals in pool water. These kits are available at most pool supply stores.
- Follow the instructions carefully to get an accurate reading of copper levels in your pool. Ideally, your pool’s copper level should be as close to 0 parts per million (ppm) as possible.

Methods to Remove Copper from Swimming Pool Water
When you’ve confirmed that copper is present in your pool, it’s time to take action. Luckily, several methods are available to effectively remove copper and restore your pool’s balance. Let’s explore the most effective approaches:
Use of a Metal Sequestrant
One of the most effective and widely used methods to remove copper from pool water is applying a metal sequestrant.
A sequestrant binds to metal ions, including copper, keeping them in suspension so they can’t form stains or react with pool surfaces.
How to apply: Follow the instructions on the product, typically adding the required amount directly to the pool water. After application, the sequestrant works to neutralize copper, preventing it from causing further issues.
Ongoing maintenance: Metal sequestrants don’t actually remove the copper from your pool. They keep it in check, meaning regular application is necessary, especially after heavy pool use or refilling.
Pool Flocculants
Another option is using flocculants, a chemical that binds small particles together so they sink to the bottom of the pool for easy removal.
How it works: Add the flocculant to the water, and over time, the copper particles will cluster together and settle at the pool floor.
Next step: Once settled, carefully vacuum the pool to remove the copper-laden debris. Make sure you use the vacuum’s “waste” setting to avoid recirculating the copper back into the pool.
This method is great for visibly cloudy pools or if the copper is causing noticeable water discoloration.
Partial Drain and Refill
In severe cases where copper levels are exceptionally high, the best solution might be to partially drain and refill the pool with fresh water.
Why it works: By diluting the contaminated water, you reduce the overall concentration of copper. However, this should be done cautiously, as draining too much water can throw off the pool’s chemistry or even damage the structure.
Best practice: Only drain a portion of the water (about one-third or half), then refill with clean, metal-free water.
Water Filter Systems
Upgrading your water filtration system can make a significant difference in removing metals from your pool water.
There are specialized filters designed to target and eliminate metals like copper.
Types of filters: Consider installing metal-specific filters or reverse osmosis systems to catch and remove copper and other metals.
Ongoing filtration: Regularly cleaning or replacing your filters ensures the system remains effective at keeping copper levels low.

Preventing Future Copper Contamination
Once you’ve removed the copper from your pool, it’s important to take steps to prevent it from coming back. Such as the following:
Regular Water Testing and Maintenance: Testing your pool water frequently is key to catching metal buildup before it becomes a problem.
It’s a good idea to test for metals at least once a month, especially if you use well water or copper-based chemicals.
Proper Use of Pool Chemicals: Be mindful of the chemicals you’re adding to your pool. Avoid copper-based algaecides or choose alternatives that don’t contain metals.
Always follow the manufacturer’s instructions when adding any pool chemicals to avoid imbalances that can lead to corrosion.
Maintaining Pool Equipment: Keep your pool equipment in top shape to prevent copper from leaching into the water.
Also, if your pool has a copper heat exchanger, inspect it regularly for signs of wear. Replacing corroded or aging equipment can save you a lot of trouble down the line.
Concluding Words
Removing copper from your pool doesn’t have to be a complicated task. By using effective methods like applying sequestrants, and flocculants, or partially draining your pool, you can restore your water to its clear, sparkling state.
More importantly, routine water testing and proper maintenance will help you prevent copper buildup in the future.
Besides, your pool should be a place of relaxation, not stress. So, take the necessary steps to keep copper at bay and enjoy crystal-clear water all summer long!
