Tip 1: Balance Water Chemistry Before Closing

Proper water balance before closing prevents staining, scaling, algae growth, and surface damage during winter months. This is the foundation of successful winterization.

Why Water Balance Matters:

• Prevents metal staining on pool surfaces
• Stops scaling from high pH or calcium
• Inhibits algae growth in cold water
• Protects pool surfaces from etching
• Ensures clean, clear water in spring
• Prevents $200-$1,000 in spring treatment costs

The Taylor K-1000 Basic Pool & Spa Test Kit provides accurate testing for proper water balance before closing.

Target Water Balance Parameters:

• pH: 7.2-7.6 (7.4 ideal for winter)
• Total Alkalinity: 80-120 ppm (100 ppm ideal)
• Calcium Hardness: 200-400 ppm (250-350 ppm ideal)
• Free Chlorine: 1-3 ppm before shocking
• Combined Chlorine: Below 0.2 ppm
• Cyanuric Acid: 30-50 ppm

Balancing Procedure:

1. Test all parameters 3-5 days before closing
2. Adjust alkalinity first (stabilizes pH)
3. Adjust pH second (most critical parameter)
4. Adjust calcium hardness third
5. Wait 4-6 hours between major adjustments
6. Retest to verify proper levels achieved
7. Proceed with winterizing chemicals only after balance

Common Water Balance Mistakes:

• Skipping testing entirely (assumes water balanced)
• Testing but not adjusting out-of-range parameters
• Adjusting pH before alkalinity (pH won't stabilize)
• Not waiting between adjustments (inaccurate results)
• Using old or expired test reagents (false readings)
