4 Steps to Remove Iron Pool Stains
Step 1: Lower chlorine to 1.0 ppm
Lower your chlorine reading to less than 1.0 ppm by either using chlorine nuetralizer or abstaining from adding your sanitizer for a few days.
Step 2 (Optional): Add Liquid Acid
Lower your Total Alkalinity by using a gallon of Muriatic Acid per 20,000 gallons. You can add more as necessary.
Step 3: Add Pool Stain Treat®
Add one (1) bottle of Pool Stain Treat® per 20,000 gallons of pool water.
WARNING: Dissolve first for color plaster, painted fiberglass & Exposed Aggregate
For colored plaster, painted fiberglass, exposed aggregate pools you will need to dissolve Pool Stain Treat® in a bucket of water first before pouring it into the swimming pool to prevent discoloration.
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 Pool Stain Treat® in a bucket of water and pour around the pool. This will help give an even finish.
TIP: Running your pump
If your pH is above 7.2, you can go ahead and let your system run. Otherwise, turn off your pump until your raise your pH to at least 7.2.
Step 4: Brush
After 5-10 minutes, brush the entire surface of the pool.
Iron Pool Stain Do's
- Reduce your chlorine to 1.0 ppm.
- Lower your total alkalinity 10 ppm or more
- Dissolve Pool Stain Treat® in a bucket first for colored plaster, painted fibgerglass and exposed aggregate
- Dissolve Pool Stain Treat® in a bucket first for widespread stains
Iron 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.
- Don’t add Pool Stain Treat® directly on to colored plaster, painted fiberglass, or exposed aggregate surfaces. This can lead to discoloration.
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.
