Salt Water Pool Systems: Choosing the Best One and Understanding Their Value

A salt water system can be an excellent investment for pool owners wanting to reduce chlorine handling and simplify pool maintenance. Before purchasing a salt water chlorinator, also known as a salt water generator, it’s essential to understand a few key points.

How Does a Salt Water Pool System Work?

A salt water pool sanitizes with chlorine just like traditional pools, but the process is different. Instead of adding chlorine directly to your water, you add salt, which the generator then converts into chlorine through electrolysis. This continuous conversion process creates a steady flow of chlorine to help maintain balanced water chemistry, saving you time and effort compared to manually adding chlorine. The pool water itself has a mild salt level—similar to that of human tears, so it won't taste like ocean water.

Benefits of Salt Water Pool Systems

1. Simplified Maintenance: With a salt water chlorinator, there’s no need for weekly chlorine additions. Just add salt, and the generator will handle chlorine production. Salt water pools also have less chlorine smell, causing less skin and eye irritation for swimmers.

2. Cost-Effective in the Long Run: While the initial cost of a salt water generator is high, you’ll save money on chlorine purchases in the future. Salt, which costs less than chlorine, is used consistently, offering long-term savings.

3. Algae and Contaminant Prevention: Salt water chlorinators provide a steady supply of chlorine, which helps prevent algae buildup and other contaminants. Many systems also feature a “super chlorination” setting that can temporarily increase chlorine levels to address any immediate sanitation needs.

Top Salt Water Pool Systems

When choosing a salt water pool system, reliable brands and models with strong warranties are essential. Here are some leading options:

1. Best Overall: Hayward Salt Chlorination System
   Hayward’s model is ideal for inground pools up to 40,000 gallons, offering simple installation and an intuitive digital display for adjusting chlorine levels. Its self-cleaning cell and durable design make it a lasting investment.

2. Compact Option: Pentair IntelliChlor Salt Chlorine Generator
   With a smaller footprint, the Pentair IntelliChlor is a great choice for tight spaces. Its easy-to-read display lets users monitor salt levels, cell conditions, and water quality, making it a versatile choice for both small and large pools.

3. Budget-Friendly: Intex Krystal Clear
   Perfect for smaller above-ground pools up to 15,000 gallons, the Intex Krystal Clear Salt Water System provides easy installation with adapters for various setups. Its programmable digital timer helps control chlorine levels efficiently.

Installation and Maintenance Tips

Salt water systems require a salt concentration around 3,000 parts per million (ppm) to function properly. Pool owners should test the salt level and ensure the generator is compatible with the pool’s plumbing setup before installation.

Considerations and Potential Drawbacks

1. Initial Investment and Replacement Costs: A salt water system costs over $1,000 upfront, with salt cells requiring replacement every 5–7 years. Regular maintenance is essential to maximize the system’s lifespan.

2. Corrosion Concerns: Salt can gradually corrode metal components, including pool fixtures and outdoor furniture. To minimize corrosion risks, rinse off any salt water on nearby surfaces and avoid excessive salt levels.

3. Electricity Usage: Salt water systems do use more electricity to power the chlorinator, especially in larger pools. However, savings on chlorine can help offset these energy costs over time.

Is a Salt Water System Worth It?

If you prefer a pool with less chlorine handling, lower long-term costs, and fewer algae issues, a salt water system is an excellent choice. While there’s an initial setup cost, the system’s ability to self-generate chlorine consistently offers convenience and cost-efficiency. Proper care and routine maintenance will help keep your salt water generator running smoothly, letting you enjoy a pool with clear, well-maintained water all season long.
