Introduction
Pool sanitation has evolved significantly over the past two decades. While traditional chlorine pools remain common, many pool owners are actively searching for cleaner, gentler, and more convenient ways to maintain healthy water. Handling chlorine tablets, dealing with strong chemical odors, and managing fluctuating chlorine levels can quickly turn pool ownership into a chore rather than a pleasure.
Saltwater pool systems have emerged as a preferred alternative, offering softer water, reduced irritation, and automated sanitation. The Pureline Crystal Pure Salt System PL7700 is designed to bring these benefits to residential pool owners with pools up to 40,000 gallons. As a complete, universal salt chlorination solution, it includes both the control panel and salt cell, making it suitable for new installations and system upgrades alike.
This in-depth Pureline Crystal Pure Salt System review explores how the system works, its sanitation process, installation experience, daily operation, safety features, performance capacity, and long-term value. If you are considering converting your pool to saltwater or replacing an aging chlorination system, this guide will help you understand whether this system meets your needs.
What Is the Pureline Crystal Pure Salt System PL7700?
The Pureline Crystal Pure Salt System PL7700 is a universal salt chlorine generator designed for residential swimming pools with capacities up to 40,000 gallons. It automatically converts dissolved salt into chlorine through electrolysis, providing continuous sanitation without the need for traditional chlorine products.
This system includes:
- A digital control panel
- A high-capacity salt cell
- Built-in safety and monitoring features
By combining automation, efficiency, and ease of use, the Crystal Pure Salt System aims to simplify pool care while improving water comfort and clarity.
Gentle Sanitation for a More Comfortable Pool
Softer Water Feel
One of the most appealing benefits of the Pureline Crystal Pure Salt System is its ability to produce softer, more comfortable pool water. Saltwater pools typically maintain lower free chlorine concentrations compared to manually dosed chlorine pools, resulting in water that feels smoother on the skin.
Swimmers often experience:
- Less eye redness
- Reduced skin dryness
- No harsh chlorine odor
- Improved comfort for hair and swimwear
This makes the system particularly appealing for families, frequent swimmers, and individuals with sensitive skin.
Reduced Fabric and Surface Damage
Traditional chlorine can be harsh on pool liners, swimsuits, and pool accessories. Saltwater sanitation helps reduce chemical stress on materials, potentially extending the life of pool surfaces and fabrics.
How the Crystal Pure Salt System Works
Saltwater Electrolysis Explained
The Pureline Crystal Pure Salt System PL7700 uses electrolysis to sanitize pool water. The process is straightforward and continuous:
- Pool-grade salt is added to the water
- Water circulates through the salt cell
- An electrical charge converts salt into chlorine
- Chlorine disinfects the pool water
- Chlorine reverts back into salt
This cycle repeats automatically, maintaining consistent sanitation without frequent manual intervention.
Natural and Balanced Disinfection
Because chlorine is generated continuously rather than added in large doses, the system helps maintain stable chlorine levels. This stability reduces the risk of algae growth, cloudy water, and sudden chemical imbalances.
Universal Saltwater Pool Compatibility
Designed for Large Residential Pools
With support for pools up to 40,000 gallons, the Crystal Pure Salt System is suitable for medium to large residential pools. Its high chlorine production capacity ensures effective sanitation even during peak swimming seasons.
Broad Equipment Compatibility
The system is designed as a universal solution, making it compatible with a wide range of residential pool equipment setups. This versatility makes it a strong choice for both new installations and retrofits.
Control Panel and User Interface
Easy-to-Read Digital Display
The system features a durable control panel with clear digital displays and LED indicators. These visual elements provide real-time feedback on system status, allowing pool owners to quickly assess performance.
Displayed information includes:
- Chlorine output level
- System status indicators
- Alerts for operational issues
Adjustable Chlorine Output
The control panel allows users to adjust chlorine output to match pool size, swimmer load, and seasonal conditions. This flexibility helps optimize sanitation while minimizing unnecessary chlorine production.
Intuitive Operation
The layout of the controls is designed for simplicity. Even users new to saltwater systems can quickly learn how to adjust settings and monitor performance.
Performance Capacity and Chlorine Output
High Daily Chlorine Production
The Pureline Crystal Pure Salt System PL7700 is capable of producing up to 2.1 pounds of chlorine per day. This high output capacity ensures that the system can keep up with the sanitation demands of large pools.
Consistent Sanitation
High chlorine production combined with continuous operation helps maintain consistent water quality. This consistency reduces the need for shock treatments and corrective chemical additions.

Self-Cleaning and Maintenance Features
Self-Cleaning Salt Cell
The salt cell is designed with a self-cleaning function that helps prevent calcium and mineral buildup. By reducing scale accumulation, the system maintains efficiency and extends the lifespan of the cell.
Reduced Manual Cleaning
Traditional salt cells often require frequent manual cleaning to remove calcium deposits. The self-cleaning feature significantly reduces this need, saving time and effort for pool owners.
Super Chlorination Mode
Boost for High-Demand Situations
The system includes a super chlorination mode, which temporarily increases chlorine output. This mode is useful after heavy pool use, storms, or periods of high contamination.
Quick Recovery
Super chlorination helps restore water clarity quickly without requiring separate shock chemicals, streamlining pool maintenance.
Safety and Monitoring Features
Water Flow Detection
The built-in water flow detector ensures that chlorine is produced only when proper circulation is present. This protects the salt cell and prevents unsafe chlorine generation.
Temperature Protection
High and low temperature protection safeguards the system against operation outside safe temperature ranges. With an operating range from 50°F to 140°F, the system is suitable for a wide variety of climates.
Electrical and Sodium Monitoring
