Pool & Spa Chemical Guide

As a retailer of pool and spa maintenance products, I've created this comprehensive guide to help you understand and maintain proper water chemistry for your pool or spa.

Water Balance Essentials

pH Levels (7.2-7.6)

The cornerstone of water chemistry that affects all other aspects of water treatment:

• Too high: Reduces chlorine effectiveness, causes scaling
• Too low: Equipment corrosion, skin/eye irritation
• Regular testing and adjustment crucial for optimal balance

Chlorine (1-3 ppm)

Primary sanitizer for most pools and spas:

• Free chlorine maintains water safety
• Stabilized chlorine provides longer-lasting protection
• Shock treatments eliminate contaminants and chloramines

Alkalinity (80-120 ppm)

Acts as a buffer for pH levels:

• Prevents rapid pH fluctuations
• Protects against corrosion
• Helps prevent scaling issues

Specialized Treatments

Water Clarifiers

Enhances filtration efficiency:

• Coagulates tiny particles
• Improves water clarity
• Reduces filter strain

Algaecides

Prevents and treats algae growth:

• Regular prevention dosing
• Brush-free formulas available
• Compatible with all sanitizing systems

Stabilizers

Protects chlorine from UV degradation:

• Essential for outdoor pools
• Extends chlorine effectiveness
• Reduces chemical consumption

Maintenance Schedule

Daily Tasks

• Check sanitizer levels
• Run filtration system
• Remove visible debris

Weekly Tasks

• Test complete water chemistry
• Balance pH and alkalinity
• Add maintenance chemicals

Monthly Tasks

• Deep clean filters
• Check stabilizer levels
• Inspect equipment

Safety Guidelines

• Store chemicals separately
• Keep in cool, dry location
• Never mix different products
• Follow dosage instructions carefully
• Keep records of all treatments
