Salt Water Pool: Truths and Myths
Saltwater pools, also known as salt systems or saltwater generators (SWG), come with their own set of myths and misconceptions. Let’s clear the confusion and uncover the truth about these systems.
______________________________
Understanding Saltwater Generators (SWG)
SWGs use regular table salt, specifically designed for pools and sold as “pool salt” in 40 lb. bags. It’s important to only use salt labeled for pools, as other types may contain additives that could stain your pool surface.

Myth #1: Saltwater Pools Don’t Use Chlorine
Truth: Saltwater pools are chlorine pools. The SWG converts salt into chlorine, maintaining your pool’s cleanliness without the need to handle or add traditional chlorine chemicals.

Myth #2: Swimming in a Salt Pool Feels Like Swimming in the Ocean
Truth: Ocean water has a salinity level of 35,000 ppm, while salt pools range between 3,100-3,400 ppm—less salty than a human tear (6,000 ppm). You’ll barely taste the salt in a saltwater pool.
While adding 400-800 lbs. of salt to your pool may seem daunting, the salt concentration is minimal compared to ocean water. Think of it as $34 in $10,000.

Myth #3: A Saltwater Pool Will Save Me Money
Truth: Saltwater pools are not cost-saving. An SWG system costs $1,000 or more upfront, with salt cell replacements every five years costing $400-$700. Over time, the cost is comparable to—or higher than—buying pool chemicals for a traditional chlorine pool.

Myth #4: Saltwater Pools Damage Decking and Equipment
Truth: Unlike the corrosive effects of ocean salt near a beach, the salinity in a saltwater pool is too low to harm your deck or equipment. There’s no need to hose down your deck after swimming, and saltwater won’t damage your pool infrastructure.

Myth #5: Saltwater Systems Are Unreliable and Hard to Use
Truth: Modern SWG systems are highly reliable and user-friendly. Most systems now include LED indicators for salt levels and operational status. The main maintenance issue is calcium buildup on the cell, which can be resolved by a simple cleaning.

Truth #1: pH Levels in Saltwater Pools Rise Rapidly
This is a common drawback of SWGs. The constant production of chlorine raises the pool’s pH.
Solutions:
•    Add borates to maintain a level of 50 ppm, reducing pH spikes.
•    Invest in a pH acid pump to automate pH balance.

Truth #2: Saltwater Pools Are Easier to Maintain, and the Water Feels Softer
One of the biggest advantages of a saltwater pool is low maintenance. The SWG adds chlorine for you, eliminating the need to handle harsh chemicals. The water feels softer on your skin, and there’s no strong chemical smell.

Bottom Line
Saltwater pools offer numerous benefits, including easier maintenance and softer water, with only a few manageable drawbacks. They’re a great option for those seeking a simpler, more enjoyable pool experience.
