Surface staining and scale can still occur if: Mineral levels are extremely high pH, alkalinity, or calcium hardness are out of balance Metals are present in source water and not addressed early Testing your water (especially metals and hardness) before opening makes preventive products like this most effective.
For best results, do the following: Test and balance your water first — ensure pH, alkalinity, and sanitizer levels are within normal ranges before adding stain & scale control. Run your pump and filter so circulation is active. Add the product evenly over the surface of your pool or spa. Avoid superchlorination/shocking within 24 hours before or after application — this can reduce performance.
Even balanced water can develop problems when dissolved metals or high mineral content are present. Without prevention, pool surfaces: Can develop discolouration stains May accumulate hard scale deposits Could experience equipment wear from scale on heaters, filters, or piping Might show brown, yellow, or green tints from oxidized metals Using a stain & scale preventative guards your pool water and surfaces so you spend less time scrubbing and more time swimming.
