Everyday Usage of Metal Out
What Is Metal Out Used For?
Metal Out is a specialized swimming pool chemical designed to eliminate and control the presence of metals such as iron, copper, and manganese in pool water. Everyday sources of these metals include fill water (especially well water), corroded pipes, certain chemicals like algaecides, and even pool equipment itself.
When metals are present in pool water, they can cause staining on pool surfaces, discolor the water, and reduce the effectiveness of chlorine. Metal Out products work by binding (chelating) metal ions in the water, preventing them from reacting with other chemicals and depositing as stains or scale.
How Do You Use Metal Out?
Metal Out is typically added directly to the pool water as part of routine maintenance or whenever you notice signs of metal contamination. Everyday situations when you should use Metal Out include:
- Opening the pool for the season.
- After topping up or refilling with water known to have high iron or copper.
- When you notice brown, green, blue-green, black, or purple stains on the pool surface.
- If pool water appears clouded or changes color after chlorine treatment.
Typical Application Steps
- Test and Balance Water: Ensure pH (7.2-7.6), alkalinity (100-120 ppm), and calcium hardness are in the proper range.
- Clean the Pool & Filter: Remove debris and clean or backwash the filter for best results.
- Calculate Dosage: Refer to the product’s label or use typically recommended volumes (e.g., 150 ml per 10,000 L for initial treatment).
- Add Metal Out: Pour the product around the pool perimeter or in front of the water return, never directly into the skimmer.
- Circulate Water: Run the filter in “Recirculate” mode (if available) for 6-24 hours to disperse the product, then return to “Filter” mode.
- Wait Before Swimming: Allow at least 1 hour (some products recommend up to 4 hours) before using the pool again.
- Monitor & Maintain: Check the filter regularly for clogging due to captured metals, and repeat as necessary or per maintenance schedule.
Key Benefits of Metal Out
Removes & Prevents Stains
- Prevents ugly brown, green, blue-green, or purple stains caused by iron, copper, and manganese.
- Eliminates existing metallic stains with regular use.
Water Clarity & Sparkle

- Maintains crystal-clear, inviting pool water.
Protects Pool Surfaces & Equipment
- Prevents scale buildup and corrosion on pool liners, ladders, steps, pumps, and heaters.
- Extends the lifespan of costly equipment.
Compatibility
- Most products are safe for use in saltwater and traditional chlorine pools.
- Many are biodegradable and will not introduce phosphates.
Easy, Proactive Maintenance
- Simple weekly or monthly application keeps metals in check.
- Reduces need for more drastic measures like partial water replacement.
How to Choose the Right Metal Out
Choosing the correct Metal Out product depends on several important factors:
1. Pool Size & Volume
Select a product with clear dosage instructions for your specific pool volume. Large pools may require higher concentration or larger bottle sizes (e.g., 4L jugs for pools over 40,000 L).
2. Metal Contamination Levels
- Light, Ongoing Use: Standard products suffice for weekly maintenance.
- Heavy Contamination: Choose extra-strength or high-capacity formulas for stubborn stains.
3. Pool Type & Equipment
- Ensure the product is compatible with saltwater systems if needed.
- If using a diatomaceous earth (DE) filter, confirm product safety (some brands recommend against using Metal Out with DE filters).
4. Eco-Friendliness & Safety
- Look for biodegradable, phosphate-free formulas to minimize environmental impact.
- Products with minimal side effects such as foaming or pH swings are preferred.
5. Application Convenience
- Seek liquid forms for easy, uniform distribution.
- Choose products with quick-acting properties and minimal waiting times.
6. Budget & Availability
- Compare cost per treatment, not just per bottle.
- Availability in larger containers may be more cost-effective for large or commercial pools.
Practical Tips, Advice, and Best Practices
Testing and Identifying Metal Presence
- Use metal-specific pool test kits to check for iron, copper, and manganese.
- Home remedies, like rubbing a Vitamin C tablet on a stain, can help confirm metal-based discoloration (if the stain lightens, it’s likely metal).
Preparing for Treatment
- Always balance pool water before adding Metal Out.
- Clean filters before and after treatment.
- Remove debris and vacuum sediments beforehand.
Application Tips
- Add Metal Out with the pump running, dispersing around the perimeter.
- Never pour directly into the skimmer, unless instructions specify.
- For severe metal problems, use an initial or shock dose followed by weekly maintenance dosing.
Aftercare
- Clean/backwash your filter within 24-48 hours; metals will collect here.
- Re-test your water for metals and pool balance a few days post-treatment.
- If stains or water discoloration recur, repeat the treatment promptly.
Avoiding Common Mistakes
- Don’t overdose—using too much can cause foaming or cloudiness.
- Don’t stop the pump/circulation immediately after dosing; continuous movement is crucial for effectiveness.
- Avoid swimming until at least 1 hour has passed post-application, or as per product label.
