6 Steps to Remove Copper Pool Stains
Step 1: Turn off your pump.
Turn off your pump system and bypass the timer.
Step 2: Lower chlorine to 0.3 ppm
Lower your chlorine reading to less than 0.3 ppm by either using chlorine nuetralizer or abstaining from adding your sanitizer for a few days.
Step 3: Lower pH to 7.2
Lower your pH to 7.2 by adding Muriatic Acid. You can add more as necessary.
Step 4: Add Super Stain Treat™
Add one (1) bottle of Super Stain Treat™ per 15,000 gallons of pool water.
TIP: Round up
Round your pool up to the nearest 5,000 gallons for dosing.
TIP: Dissolve for wide stains
For wide spread staining, dissolve Super Stain Treat™ in a bucket of water and pour around the pool. This will help give an even finish.

Step 6: Rebalance
Slowly rebalance your pool. Once your pH is above 7.2 you can turn on your pump.
Copper Pool Stain Do's
- Reduce your chlorine to 0.3 ppm.
- Lower your pH to 7.2
- Dissolve Super Stain Treat™ in a bucket first for widespread stains
Copper Pool Stain Don'ts
- Don’t run the filter or allow the pump to kick on if your pH is below 7.2.
- Don’t add lots of balancers or shock at one time. This can cause staining.
Stain Prevention Tips
TIP 1: Balance with the Hamilton Index™
Lower your Total Alkalinity relative to your water hardness according to the Hamilton Index™
TIP 2: Minimize Shocking
Avoid shocking more than necessary. Shocking can lead to metals dropping out of the water and staining.
TIP 3: Dissolve before adding balancers
When using a non-liquid balancing chemical (such as pH increaser or granular acid), dissolve it first and pour it around the pool. This will minimize chances of metal staining.
TIP 4: Avoid baking soda for balancing
Switch from using baking soda to soda ash or borates to minimize chances of reacting to metals and forming stains.
TIP 5: Avoid metal algicide
Avoid using copper and silver based algicides that lead to staining.
TIP 6: Use a Stain Preventative
Consider using a preventative stain treatment such as Pool Stain Treat® to keep stains from returning.
