Introduction: Precision Dosing for Maximum Scale Inhibition

Achieving a 98% scale inhibition rate with our food-grade NSF certified polyphosphate scale inhibitor requires not only a high-quality product but also precise dosage. This guide provides detailed dosing tables for both Point-of-Use (POU) and Point-of-Entry (POE) applications, ensuring you can effectively prevent limescale in everything from under-sink RO systems to whole-house boilers. Based on rigorous testing, these recommendations help you optimize performance, extend appliance lifespan, and maintain water clarity.

Part 1: Understanding POU vs. POE Dosage Fundamentals

The dosage of our anti-scaling balls varies significantly depending on the application type. The key difference lies in the volume of water being treated.

POU (Point of Use) Dosage: Designed for treating water at a single outlet, such as a water filter, coffee machine, or ice maker. The water flow and volume are lower, requiring a smaller amount of scale inhibitor.

POE (Point of Entry) Dosage: Designed for treating all the water entering a building. This protects water heaters, boilers, washing machines, and all other water-using appliances. Due to the higher total water flow, the required dosage is substantially greater.

The following tables are based on standard testing conditions (Water TDS: 400-500 ppm, Temperature: ~20°C).

Part 2: Advanced Dosing: Adjusting for Water Hardness (TDS)

Total Dissolved Solids (TDS) is a key indicator of water hardness. The higher the TDS, the greater the scaling potential, and the more scale inhibitor is required. The comprehensive table below provides dosage recommendations for a wide range of water conditions, from soft to very hard water.

Part 3: Pro Tips for Optimal Performance and Troubleshooting

 Start with the Minimum Dosage: Begin with the lower recommended amount for your TDS and ball size. You can always increase it if needed.

 Monitor and Adjust: The provided tables are a scientific starting point.

 If water becomes turbid: This may indicate over-dosing. Slightly reduce the amount of scale inhibitor balls.

 If scale still appears: This signals under-dosing. Slightly increase the amount of balls used.

Consider Flow Rate: The product is designed to dissolve slowly in flowing water. Ensure it is installed in a location with consistent water flow for even dissolution and long lifespan.
