Many homeowners are misled by the widespread belief that “saltwater pools are chemical-free.” The truth is, saltwater pools still rely on chemicals—just in a different form compared to traditional chlorine systems.

At M&M Pool & Spa Services, your trusted South Florida pool professionals, we believe in educating our customers about the realities of saltwater sanitation to ensure safer, cleaner, and properly maintained pools year-round.

Understanding the Saltwater Sanitation Process

Saltwater pools use a process called saltwater sanitation, wherein pool-grade salt (sodium chloride) is converted into chlorine through a salt chlorine generator (SCG). This process is known as electrolysis and functions continuously to disinfect the pool water. Contrary to the myth, this system still uses chlorine—just not in the form of manually added tablets or granules.

So, Why the Confusion?

The term “saltwater pool” often gives the impression of ocean-like water that’s naturally clean and completely free of harsh chemicals. Here’s why people might believe the myth:

  • Marketing materials often hype “softer water” and “natural systems”
  • The chlorine smell and eye irritation are often less noticeable
  • There is no need to handle traditional chlorine products directly

However, the chemical truth is that chlorine is still present—it’s just generated automatically through electrolysis rather than added manually.

Saltwater Pools Still Require Maintenance and Chemicals

Although saltwater pools generally offer a more consistent chlorine level, they still require attention and regular upkeep. Understanding these needs helps extend the life of your equipment and ensures water quality and safety.

Ongoing Maintenance Requirements

M&M Pool & Spa Services recommends regular maintenance routines, especially for saltwater systems. Neglecting even a saltwater pool can lead to expensive damage or unsafe water conditions.

Key Maintenance Tasks for Saltwater Pools:

  • Monitor salt levels: Ideal salt concentration ranges between 2,500–3,500 ppm, depending on your generator’s specifications.
  • Test water chemistry: Even saltwater pools need regular pH, alkalinity, calcium hardness, and cyanuric acid adjustments.
  • Clean the salt cell: Calcium and other minerals can build up on the cell, which must be cleaned every few months.
  • Check and balance chlorine output: Overproduction of chlorine can still lead to irritation and accelerate equipment wear.

Regular water testing is essential, as imbalanced water chemistry can corrode your pool equipment and surfaces—even in saltwater systems.

The Chemical Truth: Saltwater vs Traditional Chlorination

Both saltwater and traditional pools depend on chlorine to sanitize the water. The key difference lies in how the chlorine is added:

  • Saltwater pools: Generate chlorine automatically through salt conversion
  • Traditional pools: Require manual application of chlorine products like tablets, powders, or liquid chlorine

In both systems, chlorine works to eliminate harmful bacteria, algae, and other pathogens. Therefore, the idea that saltwater pools are chemical-free is simply inaccurate. They are, however, less harsh and involve different chemical handling practices.

Why South Florida Pool Owners Should Be Aware

In warm, humid areas like Miami-Dade and the greater South Florida region, your pool gets more use and is subject to more environmental exposure—such as UV rays, rain, and organic debris. This makes it even more critical to understand and stay on top of saltwater pool maintenance.

Benefits of Saltwater Pools in South Florida

  • Lower daily chemical costs: Chlorine is produced continuously from salt
  • Softer-feeling water: Easier on the skin and eyes
  • Reduced chlorine smell: Minimal chloramines are produced compared to traditional pools

However, South Florida pool owners should also be aware of the unique challenges that saltwater pools present:

  • Higher equipment corrosion risk: Salt is more corrosive in humid, salty air environments
  • Calcium and scale buildup: More prevalent in hard water regions like Miami-Dade
  • Increased maintenance complexity: Salt cells, flow sensors, and control units require regular inspection and service

At M&M Pool & Spa Services, we provide specialized saltwater system services tailored to South Florida’s climate—offering everything from salt cell inspection to full water balance treatments.
