Professional Grade Hardness Plus – 25kg Bulk Container

As a retailer of hot tub and pool maintenance products, I’m pleased to offer this professional-grade calcium hardness increaser in a robust 25kg container, ideal for commercial applications and larger water systems.

Product Overview

This commercial-size 25kg container of Hardness Plus is a professional-strength calcium hardness increaser, specifically formulated for maintaining optimal water chemistry in larger pools, multiple spa systems, or high-usage facilities.

Professional Applications

This bulk container is particularly suited for:

• Commercial pool facilities
• Multiple system maintenance
• Large residential pools
• Aquatic centers
• Year-round maintenance planning
• Professional pool service providers

Why Calcium Hardness Matters

Proper calcium hardness levels are crucial for protecting pool and spa systems. When calcium levels fall below recommended levels, water becomes aggressive and can:

• Deteriorate pool surfaces
• Damage essential equipment
• Reduce heater efficiency
• Create water balance issues
• Lead to premature system aging

Application and Usage

Professional-grade formula designed for precise control:

• Dosage: 68g per 4,545 litres (1,000 gallons) to increase calcium hardness by 10ppm
• Target Range: Maintain between 200-300ppm
• Application Method: Direct addition during circulation

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
