Metal Staining Advanced

Metal stains result from dissolved metals in pool water that oxidize and precipitate onto surfaces. Common sources: corroded copper heat exchangers creating blue-green stains, iron from well water or rusted equipment causing brown stains, manganese from groundwater creating black stains, and low pH dissolving metals from equipment. High chlorine levels accelerate metal precipitation.

Use the vitamin C test: crush a vitamin C tablet on the stain underwater and hold for 30 seconds. Metal stains lighten or disappear immediately, while organic stains show no change. Copper stains are blue-green, iron stains are brown/rust-colored, manganese stains are dark brown/black. Location and pattern also help - metal stains often appear around equipment or in shallow areas first.

Remove copper stains with ascorbic acid treatment: Lower pH to 7.0-7.2, add metal sequestrant to bind dissolved copper, apply ascorbic acid directly to stains (broadcast for widespread stains), circulate water 24 hours, brush stains gently, monitor and adjust pH, add maintenance sequestrant. Success rate is 90-95% on fresh stains.

Remove iron stains using similar ascorbic acid process as copper: Test with vitamin C to confirm iron stains, add metal sequestrant first, apply ascorbic acid treatment, maintain circulation, brush affected areas. Iron stains may require higher ascorbic acid doses. Address source (well water treatment, equipment corrosion) to prevent return.

Ascorbic acid (vitamin C) is a powerful reducing agent that reverses metal oxidation, removing metal stains from pool surfaces. It's safe for all pool types, works immediately on contact, doesn't damage equipment, and can be used while pool is filled. Typically requires 1-2 lbs per 10,000 gallons for treatment. Must be followed by metal sequestrant.

Metal sequestrants prevent new stains and can help with light staining, but are not effective for heavy, set-in stains. They bind dissolved metals in water, preventing precipitation. Use HEDP or EDTA-based products at 32-64 oz initial dose per 20,000 gallons, then 8-16 oz weekly maintenance. Best for prevention and high-metal source water.

Recurring metal stains indicate an ongoing metal source: corroded copper heat exchanger (most common), low pH causing equipment corrosion, well water with high iron/copper/manganese, copper ionizers or algaecides, galvanic corrosion from improper bonding. Must identify and fix source - stain removal is temporary without source control.

Yes, prevent metal stains through: maintaining pH 7.2-7.6 to prevent equipment corrosion, testing source water for metals and treating if needed, regular equipment inspection and maintenance, using metal sequestrants in high-metal areas, proper electrical bonding to prevent galvanic corrosion, avoiding copper-based algaecides if prone to staining.

Metal stain removal costs $200-800: DIY with ascorbic acid and sequestrants ($50-150), professional ascorbic acid treatment ($300-600), severe cases requiring acid washing ($800-2000+). Prevention through proper chemistry management costs much less. Early treatment is most effective and economical.

Call professionals for: stains covering over 25% of pool surface, multiple DIY removal attempts failed, very dark or set-in stains over 1 year old, expensive surfaces (new plaster, tile, etc.), recurring stains indicating source problems.
