As a retailer of hot tub and pool maintenance products, I’m pleased to offer this convenient multi-pack of our professional-grade calcium hardness increaser, perfect for larger pools or seasonal maintenance planning.

Product Overview

This professional bulk pack contains 4 x 5kg containers of Hardness Calcium Plus, providing you with a total of 20kg of premium water treatment. This quantity is ideal for maintaining optimal calcium hardness levels throughout multiple seasons or for larger water volumes.

Value Proposition

The multi-pack format offers several advantages:

• Bulk quantity convenience
• Reduced packaging waste
• Always have backup supply available
• Ideal for commercial applications
• Perfect for larger pools or multiple systems

Why Calcium Hardness Matters

Maintaining proper calcium hardness is crucial for water chemistry balance. Low calcium levels (below 200ppm) can cause:

• Premature equipment wear
• Surface etching
• Heater element damage
• System efficiency reduction
• Water quality issues

Application and Usage

This professional-grade treatment is precisely formulated for reliable results:

• 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 to circulating water

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
