What Pool Pros Actually Pay for Liquid Chlorine (By State)

Liquid chlorine is your biggest recurring expense. But depending on where you live and who you buy from, you could be paying $1.79 a gallon or $6.00 a gallon for the same product.

We collected real prices from over 40 pool service professionals across the country. No estimates. No averages from a chemical manufacturer's website. Just what actual pool pros are paying right now at the counter.

Price Overview: The Big Picture

Here is what stands out from the data. Florida is the cheapest state for liquid chlorine by a wide margin. California and Nevada are the most expensive. And the gap between the best and worst price in a single state can be $2 or more per gallon.

Liquid Chlorine Prices by State

All prices below are for 12.5% sodium hypochlorite (the standard concentration for pool pros) reported in early 2026. We normalized case prices and 2.5-gallon jug prices to a per-gallon figure for comparison.

Florida

Florida has the cheapest liquid chlorine in the country. High demand, many suppliers, and year-round pool season keep prices low.

Region	Supplier	Price/Gallon
South FL (FLL)	Distributor	$1.79
SW Florida	Distributor	$1.78
Central FL	Horner	$1.80
Central FL	SCP	$1.96
SE Florida	Distributor	$1.98
North FL	SCP	$1.96
Bradenton	Heritage	$1.98
Central FL	SCP	$1.94
Tampa	Leslie's Pro	$2.00
Florida Keys	Distributor	$4.00

Most Florida pros pay between $1.79 and $2.00 per gallon. The outlier is the Florida Keys, where shipping costs push prices much higher.

"I'm in Florida. SCP's $1.96 and Horner's $1.79/gal."

If you are running a route in Florida and paying more than $2.00 a gallon, you should call Horner or SCP. You might be overpaying by 50% or more compared to the pro next door.

California

California prices vary widely depending on how you buy. Filling your own jugs at a distributor can save you more than $2 per gallon compared to buying pre-packaged cases.

Region	Supplier	Price/Gallon
California (fill own jugs)	Distributor	$3.84
California	Distributor	$4.50
Sonoma County	SCP	$6.00
Los Angeles	SPPI	$6.00

"$3.84 California but we fill our own jugs."

— Pool pro via Facebook

The lesson in California is clear: filling your own 2.5-gallon jugs at a bulk depot saves real money. A route with 80 pools using 2 gallons each per week would save over $170 a week switching from $6.00 cases to $3.84 bulk fill.

Arizona

Arizona sits in the middle. Prices cluster between $4.70 and $5.32 per gallon.

Region	Price/Gallon
Arizona	$4.70
Phoenix	$5.32

Arizona pros do not have the same low-cost bulk options Florida does. But at $5 a gallon, chlorine is still cheaper than most people think when you compare it to tablet costs.

Nevada

Las Vegas prices hover around $6.00 per gallon, making it one of the most expensive markets for liquid chlorine.

"In Vegas we were around $6 a gallon."

State	Price/Gallon	Notes
Michigan	$4.12
Louisiana	$2.60	Bulk pricing, Baton Rouge
Spring Hill, FL	$1.98	$4.95 per 2.5-gal jug

Why Prices Vary So Much

A $4 per gallon gap between states seems extreme for the same chemical. Here is what drives it.

1. Proximity to Manufacturing

Sodium hypochlorite is heavy and degrades fast. It cannot be shipped across the country like dry chemicals. The closer you are to a manufacturing plant, the cheaper it is. Florida has dozens of producers. Nevada has very few.

2. Bulk vs. Pre-Packaged

This is the single biggest pricing factor you can control.

"You need to specify whether you have to pump your own chlorine into two and a half gallon refillable jugs or if you're just buying a case of 4 gallons."

— Pool pro via Facebook

A case of four one-gallon jugs from Leslie's might run $19.50 to $23.00. That is $4.88 to $5.75 per gallon. The same chlorine from a bulk depot where you fill your own containers can be under $2.00 a gallon in many states.

3. Supplier and Account Tier

Not all pool supply distributors charge the same price. SCP (now SRS Distribution), Horner, Heritage, and Leslie's Pro all have different pricing tiers based on your volume and account history.

"They do have different prices for different people. Gotta ask to get a lower price when you been with them for awhile."

— Pool pro via Facebook

If you have never asked your distributor for better pricing, do it this week. Many pros report getting discounts just by asking, especially once they hit a consistent monthly volume.

4. Retail vs. Pro Pricing

Walmart sells liquid chlorine for about $5 a gallon, but it is usually only 10% concentration. That means you need 25% more product to get the same sanitizing power as 12.5% pro-grade sodium hypochlorite.

"9.99 for 12.5%. Walmart's is only 10%."

— Pool pro via Facebook

Always compare prices at the same concentration. A cheap gallon of 10% chlorine is not actually cheaper than a more expensive gallon of 12.5%.

How to Compare: Average Cost per Gallon by State

Based on the prices reported, here is how states stack up visually.

How Chlorine Cost Affects Your Bottom Line

Chlorine cost matters more than most pros realize. A solo operator with 80 pools using about 2 gallons per pool per week goes through roughly 640 gallons a month. Here is what that looks like at different price points.

Price/Gallon	Monthly Cost (640 gal)	Annual Cost
$1.80 (FL bulk)	$1,152	$13,824
$3.00 (mid-range)	$1,920	$23,040
$4.50 (CA/AZ)	$2,880	$34,560
$6.00 (NV/CA retail)	$3,840	$46,080

The difference between the cheapest and most expensive scenario is over $32,000 a year. Even within the same state, switching from retail cases to a bulk distributor could save you $10,000 or more annually.

5 Ways to Lower Your Chlorine Cost

1. Switch to a Bulk Depot

Stop buying cases. Find a local chemical depot where you can fill your own 2.5-gallon jugs. This one change can save 30 to 50% per gallon in most markets.

2. Ask Your Distributor for Pro Pricing

If you are buying from SCP, Horner, Heritage, or another distributor, ask about volume discounts. Many pros report getting better pricing simply by asking or by hitting a monthly volume threshold.

3. Compare Multiple Suppliers

Do not assume all distributors charge the same. The Facebook data shows Horner at $1.79 and SCP at $1.96 in the same Florida market. Over a year, that $0.17 per gallon adds up to over $1,300 on 640 gallons a month.

4. Track Your Usage

You cannot lower costs if you do not know what you are spending. Track how many gallons you use per week and what you pay. If you use PoolDial's chemical tracking, this happens automatically as your techs log service visits.

5. Check the Concentration

Make sure you are comparing 12.5% to 12.5%. Retail chlorine from big box stores is often only 10% concentration. You need 25% more of it to do the same job, which wipes out the "savings."

The Supplier Landscape

Here are the major suppliers pool pros mentioned and their general pricing tiers.

Horner (Florida) consistently came in at the lowest reported prices. Multiple pros reported $1.79 to $1.80 per gallon. If you are in Florida and not buying from Horner, it is worth a call.

SCP / SRS Distribution is the largest pool supply distributor in the U.S. Florida prices run $1.96 to $2.00 per gallon. In California, SCP prices jump to $6.00 per gallon in some markets.

Heritage Pool Supply was reported at $1.98 per gallon in the Bradenton, FL area. Competitive with SCP.

Leslie's Pro offers pro pricing separate from their retail stores. Several pros reported $4.88 to $5.00 per gallon for pre-packaged cases ($19.50 per case of 4). This is more expensive than bulk distributors but convenient for smaller operators.

SPPI (Los Angeles) was reported at $6.00 per gallon, or $24.00 per case. This is at the high end nationally.

Should You Switch to Tabs or Cal Hypo?

Some pros wonder if trichlor tabs or calcium hypochlorite (cal hypo) would be cheaper than liquid. The short answer: it depends on your market.

Trichlor tabs are convenient but add CYA (cyanuric acid) to the water with every application. Over time this creates a CYA buildup problem that costs you money in drains and dilutions. Our CYA guide covers this in detail.

Liquid chlorine (sodium hypochlorite) does not add CYA. For weekly maintenance in warm climates, most experienced pros prefer it. The cost per gallon might be higher than tabs on paper, but the total cost of ownership is lower when you factor in CYA-related issues.

Bottom Line

Chlorine pricing is not something you set and forget. Where you buy matters. How you buy matters. And checking your costs once or twice a year can put thousands of dollars back in your pocket.

If you are in a high-cost state, focus on finding a bulk fill option. If you are in a low-cost state, make sure you are actually getting the low-cost rate and not paying retail.

The pros paying $1.79 a gallon are not lucky. They just found the right supplier and asked for the right price.
