Saltwater Pool vs Chlorine for New Orleans Pools

Short version: a saltwater pool is easier on your skin and cheaper to run, but costs more upfront and stings more when the salt cell dies. Chlorine is cheaper to install and dead simple to fix, but you become a part-time chemist who smells like a public pool. Neither one is "better" — they are better at different things.

Now the part nobody tells you at the pool store: a saltwater pool is a chlorine pool. It just makes its own chlorine instead of asking you to haul it home in a bucket. So this whole debate is less "salt vs chlorine" and more "do you want to manufacture your sanitizer or buy it by the jug." Which makes it a question about which chore you would rather own: a small machine, or a standing weekly errand. Here is how that plays out in a New Orleans backyard.

The 30-second comparison

	Saltwater	Chlorine (traditional)
Upfront cost	Higher (salt cell + board)	Lower
Yearly running cost	Lower (~$70–$100 salt)	Higher (~$300–$800 chemicals)
How the water feels	Soft, less harsh	Stronger "chlorine" feel
Maintenance style	Set it and check it	Hands-on, frequent
Big repair	Salt cell every 3–7 yrs	Rarely anything major
Equipment wear	Salt is tough on some metals	Gentler on hardware

If you hate that table already, here is the one-liner: pay more now to do less later (saltwater), or pay less now and stay hands-on (chlorine).

Cost: where your money actually goes

Everyone asks which is "cheaper," which is like asking whether renting or buying is cheaper — depends how long you're staying.

• Saltwater costs more to set up because you're buying a salt chlorine generator (the cell) and a control board. Then it's cheap to run: salt is a few bags a year. The gotcha is the cell itself, a $200–$700 part that wears out every 3 to 7 years. Skip cleaning it and you'll be shopping for one sooner.
• Chlorine is cheap to install and there's no expensive part waiting to fail. You just pay steadily, all season, in tablets, shock, and the stabilizer that keeps New Orleans's sun from burning your chlorine off by noon.

Over ten years the two usually land in the same ballpark. You're really choosing when you want to spend the money, not how much.

Upkeep: chemist vs. babysitter

A chlorine pool wants attention. You test, you add tablets, you shock it after a pool party, and if you go on vacation during a LA heat wave you may come home to something with its own ecosystem.

A saltwater pool wants consistency. The generator trickles in chlorine around the clock, so levels stay flat instead of spiking and crashing. You still test the water, still balance pH, and still clean the salt cell a few times a year — anyone who told you saltwater is "maintenance-free" was selling you the generator. It's less work, not no work.

The honest test: if checking your pool feels like a chore you'll skip, saltwater's steadiness will save you from yourself. If you actually enjoy fussing with it on a Saturday, chlorine gives you the control.

How the water feels (the reason most people switch)

This is the one that wins arguments. Saltwater keeps chlorine low and even, so you skip the red eyes, the itchy skin, and the swimsuits that fade three shades by August. The water feels silkier — that's the salt, at about a teaspoon per gallon, nowhere near ocean-salty.

Chlorine done right feels fine too. The trouble is chlorine done right means staying on top of it, and by mid-New Orleans-summer a lot of pools are running hot on chlorine because the owner over-corrected after a green scare. Saltwater just makes it harder to get there.

So which one for a New Orleans pool?

Most comparisons end in a shrug at this point. Ours does not — find the line below that describes you:

• Choose saltwater if you want low-effort, gentle water and you plan to keep the pool for years. In Greater New Orleans and the Northshore's long swim season, the lower chlorine feel is genuinely nicer, and the running-cost savings add up over a long season.
• Choose chlorine if you want the cheapest install, you're comfortable being hands-on, or you're not sure how long you'll own the place.
• Skip both decisions if you just want it handled — that's what we're for.

One local note: New Orleans's hard water and heat are rough on equipment either way, and salt is a little rougher. Good stainless hardware and a heater rated for salt matter here. That's exactly the kind of thing that separates a pool that lasts 20 years from one that nickel-and-dimes you — and it's why we spec equipment for the climate, not the catalog.

What converting actually involves

If you already have a chlorine pool and you're curious, the conversion is smaller than people expect. A salt chlorine generator gets plumbed into the return line after the filter and heater, the control board mounts on the equipment pad, and a licensed electrician ties it into a dedicated circuit. Then you dissolve in the salt, and this is where people underbuy: 3,000 ppm in 20,000 gallons is about 500 pounds, so budget eleven to fifteen 40-pound bags to land in the 2,700 to 3,500 ppm most systems want.

Most conversions are a one-day job in the $1,200 to $2,500 range installed, depending on the cell size and how cooperative your existing plumbing is.

Two things to sort out before you commit. If your pool was replastered in the last 30 days, wait — new plaster needs to cure before salt goes in. And if you have a heater with a copper heat exchanger, older mild-steel ladder anchors, or natural stone coping that has never been sealed, budget for those, because salt finds every weak metal on the property eventually.

Three myths worth killing

• "Saltwater is maintenance-free." It isn't. You still test, still balance pH, and still clean the cell two or three times a year. It's less work, not no work.
• "You can't shock a saltwater pool." You can and sometimes you should. Most systems have a boost or superchlorinate mode, and after a party or a storm a bag of regular shock is completely fine.
• "Salt ruins pools." Salt at 3,000 ppm is roughly a tenth of seawater. It's rough on unsealed stone and cheap metal, and utterly indifferent to properly specified equipment.

The bottom line

Saltwater vs chlorine isn't good vs bad. It's pay-more-now-do-less-later vs pay-less-now-stay-involved. Pick the trade-off that fits how you actually live, not the one the internet yelled loudest about.
