Saltwater pools have become increasingly popular in South Florida. Here is a clear look at how they work, what they cost, and whether one is right for you.
How Saltwater Systems Work
A saltwater pool is not chlorine-free. Instead of manually adding chlorine, a salt chlorine generator converts dissolved salt into chlorine through electrolysis. The salt level in the pool is roughly one-tenth of ocean water, so it is barely noticeable. The system produces a steady, consistent level of chlorine automatically.
Benefits
Saltwater pools offer a noticeably softer feel to the water. Swimmers often report less eye irritation and skin dryness. The automated chlorine production reduces the need for manual chemical dosing and eliminates the handling and storage of liquid or tablet chlorine. Many homeowners find the water quality more pleasant overall.
Costs
A saltwater chlorine generator typically adds $1,500 to $3,000 to your equipment package. The salt cell, which is the component that generates chlorine, has a lifespan of 3 to 7 years and costs $400 to $800 to replace. Salt itself is inexpensive, and you will use less supplemental chlorine.
Considerations
Saltwater systems are highly compatible with fiberglass pools. The gelcoat surface is resistant to salt exposure, unlike some concrete finishes. However, salt can be corrosive to certain metals and natural stone. Equipment and materials should be selected accordingly, which is something we address during the design phase.
