Salt Water Pool Pros and Cons – Advice from Bob Lowry

“Salt pool, no chlorine” might be the most expensive misunderstanding in pool care. We walk through what a saltwater chlorine generator actually does, why it is literally making chlorine, and how that simple truth changes the way you test, dose, and explain water balance to customers. If you’re a pool service professional or a hands-on pool owner, you’ll leave with clearer language, better troubleshooting steps, and fewer surprises on Monday morning.

We also get into the parts that sales sheets skip: salt splash-out that dries on decks and hardware, the corrosion that shows up when salt is over-added, and why bonding and grounding matter more once your pool becomes an ionic solution full of metals. 

Then we tackle the “flakes” problem and the myths that cling to it. We explain why flakes are usually calcium carbonate, how a hot cell after flow stops can trigger scale, and how a simple cool-down period plus a slightly negative LSI can reduce buildup. 

• saltwater systems generating chlorine through electrolysis, same sanitizer as liquid or dry chlorine
• cell lifespan tied to total run hours, lowering output and run time when demand allows
• manufacturer salt targets around 3,000 to 3,500 ppm and why over-salting creates new problems
• salt splash-out leaving concentrated salt on decks and features, rinsing to prevent crust and damage
• galvanic corrosion risks, black deposits near metals, bonding and grounding pool equipment
• heater corrosion concerns and when a sacrificial zinc anode can help
• dealing with a failed generator, draining and refilling to reduce salt and high TDS, removing the cell housing
• verifying salt with an independent salt meter, not trusting onboard readings or a TDS meter alone
• preventing flakes with a cool-down period before flow stops and managing LSI slightly negative
• phosphate fears put in perspective, flakes usually calcium carbonate not calcium phosphate
• fixed-output chlorine production, recovery time after bather load spikes, supplementing with liquid chlorine
• “superchlorinate” misconce
