API Water API Pepper Salt Water Pool Balancer 2 lb — White Granular, Reduces Scale & Phosphates

API Pepper is a white granular pool balancer designed for salt water systems to reduce scale and corrosion while keeping phosphate levels low.

Keep your salt water pool equipment running efficiently with API Water's API Pepper. This two-pound granulated formula works alongside salt chlorine generators and pool hardware to slow mineral deposits, support sanitizer performance, and help manage phosphate concentrations that can interfere with water clarity and sanitizer activity. Easy to apply and safe for typical pool surfaces when used as directed, API Pepper is intended as part of a routine pool maintenance plan rather than a one-time fix.

How does API Pepper protect my salt chlorine generator?

API Pepper reduces the formation of scale on generator cells by binding minerals that tend to precipitate at the cell surface. That helps maintain cell efficiency and reduces cleaning frequency, which can extend the cell’s operational life.

• Formulated to limit mineral buildup on titanium and coated cells
• Less frequent manual cell scraping or chemical cell cleaners
• Helps preserve consistent chlorine output from the generator

Will this product help my pool water clarity and sanitizer performance?

By helping keep phosphate levels low and minimizing scale, API Pepper supports the overall effectiveness of your sanitizer. Clearer water results when sanitizers can work without interference from organics or mineral haze.

• Supports more reliable sanitizer contact with contaminants
• Helps reduce cloudy water caused by suspended mineral particles
• Works in tandem with routine filtration and sanitizing practices

How do I use API Pepper safely and when should I add it?

Follow the label directions for dosing based on pool volume and current water chemistry. Add the granules with the pump running and distribute them evenly; avoid dumping concentrated piles directly onto pool surfaces to prevent staining or localized pH shifts.

• Test pH, alkalinity, salt, and phosphate levels before treatment
• Add with circulation on and allow the system to run for several hours
• Retest water after 24–48 hours and repeat dosing per label if needed

Does API Pepper affect pool surfaces or equipment warranties?

When used according to instructions, the granular formula is compatible with common pool surfaces and equipment. Still, check your equipment manufacturer’s warranty and the product label to confirm compatibility and avoid voiding warranties from improper chemical use.

• Designed for salt water pools and compatible materials when used correctly
• Not a substitute for manufacturer-recommended cleaning or maintenance
• Always follow dosage guidelines to protect finishes and seals

Who is this for: API Pepper is made for pool owners and service professionals who operate salt chlorine generators and want a preventive maintenance product to limit scale, support sanitizer effectiveness, and help manage phosphate levels. It's best suited for routine preventative treatment rather than emergency remediation, and for anyone following a structured testing and treatment schedule to keep pool chemistry balanced.
