Historical chlorine prices

Instead of constantly adding chlorine manually, a salt pool system uses a chlorine generator to produce the perfect amount of chlorine as needed.

It doesn’t make your pool completely maintenance-free—you’ll still need to monitor water chemistry, skim, and vacuum—but it significantly reduces the expense and hassle of buying, adding, handling, and storing chlorine.

In this guide, we’ll dive into the benefits of saltwater systems for above ground pools, including how to convert, maintain, and get the most out of your swim season.

What is an above ground saltwater pool?

An above ground saltwater pool operates using a salt chlorine generator, which converts salt into chlorine through a process called electrolysis. This keeps your water clean and clear with far less effort and expense than traditional chlorine pools.

Unlike manually adding chlorine every few days, a saltwater system automatically generates a precise amount of chlorine whenever the pump is running, so you spend less time managing chemicals and more time enjoying your pool.

Above-ground saltwater pools are often more cost-effective in the long run. Over three years, above-ground pool owners can save anywhere from $600 to $1,800 on chemical costs alone ¹.

And beyond the savings, there’s the comfort—saltwater pools are much gentler on your skin, hair, and eyes.

Can an above ground pool be saltwater?

Yes! Above ground pools can absolutely be saltwater. Whether you’re setting up a new pool or converting an existing one, a saltwater system can be a great option.

Saltwater systems work just as well with above ground pools as they do with inground pools. The key is to consider what type of above-ground pool you have. Is it “temporary” or “permanently-installed?”

This comes down to two main things:

1. Ensure that your pool’s components (like frame and fixtures) are long-lasting pool-grade materials.
2. How the pool equipment system is plumbed (if it uses hoses, flex pipe, or rigid PVC).

Are all above ground pools saltwater compatible?

Not all above ground pools are intended to last. Some prioritize low price at the expense of durability. These run the risk of corroding away after being in contact with chlorinated water. If you’re investing in a salt chlorinator, you’ll want to do this on a permanently-installed above ground pool which is designed to be in place for decades that uses high-end, pool-grade materials.

But let’s get into the specifics.

Pool Components and Materials

If your pool is the 'permanent' type—built with pool-grade materials like aluminum, resin, and stainless steel—no need to worry about the low salt levels from a chlorine generator. These materials are designed to handle even harsher, long-term exposure to chlorine.

If considering an above ground pool, be sure to opt for high-grade components, or check for pools labeled as 'above-ground salt pools,' where the manufacturer has already ensured they’re made with quality, salt-safe materials.

For temporary pools, which are generally meant to last only a few years, it’s a different story. Materials like galvanized steel, often used in walls, rails, and inlets, can corrode quickly—even if they’re coated. Corrosion can speed up due to ‘galvanic action, where mixed types of metals are in contact with the pool water. For more details on how to protect your pool from corrosion, check out our pool corrosion guide, where we cover everything from improper materials and material suggestions and tips to proper pool bonding.

Pool System & Plumbing

Additionally, permanently-installed pool types typically have plumbing for the pool system which makes it easy to incorporate salt chlorine generators. If an above-ground pool uses 1.25” hoses or 1.5” hoses or PVC plumbing, it is often a simple task to add a chlorine generator into the plumbing.

Temporary above ground pools may not easily incorporate a salt chlorine generator into the plumbing. This can especially be true if the above ground pool is inflatable or doesn’t utilize a circulation system!

Note that some above-ground style salt chlorine generators make installation very easy by having a design that eliminates plumbing and simply hangs over the side of the pool, such as the Saltron Retro or Controlomatic Megachlor.

One last tip: if you’re simply unsure about your pool’s components or worried about corrosion, adding a zinc anode is a simple retrofit that helps with pool bonding and draws any potential galvanic action away from other parts. And if you still have questions about compatibility, play it safe—check with your pool manufacturer before investing in a saltwater system for your above-ground pool.

Do I need to drain my above ground pool before conversion?

No need to drain your pool, but you will want to balance the water first! Before converting to saltwater, it’s important to test your current water chemistry.

You’ll want to adjust pH, alkalinity, and calcium hardness levels first, since balancing these levels could require adding water. If you haven’t been keeping up with the pool, you may need to add a little chlorine to kill off any algae or micro-organisms that could cause maintenance to be an uphill battle after conversion.

Once your water is properly balanced, you can simply add the salt to the pool water and add the salt chlorine generator to the pool system. Your salt chlorine generator will handle the rest, turning the salt into chlorine and keeping your pool clean without the constant manual upkeep.

Do I need to change my pump or filter before I convert my above ground pool to saltwater?

Good news—no major upgrades necessary! One of the best parts about converting to a saltwater pool is that your existing pump and filter are usually good to go.

Salt systems are designed to work seamlessly with most existing above ground pool equipment, so you don’t have to worry about splurging on a new pump or filter.

Salt chlorine generators create the chlorine your pool needs without putting extra strain on your pump or filter. As long as your current setup is in good shape, it’ll handle the switch like a pro!

Switching to a saltwater pool doesn’t require a full equipment overhaul. As a matter of fact, once you buy your saltwater conversion kit for above ground pools, it can take as little as 15-60 minutes to complete the conversion depending on the model.

How to choose a saltwater pool system for my above ground pool

Picking the right saltwater system for your above ground pool starts with knowing your pool’s size and type. Why? Because the size of your pool directly determines the power and capacity of the salt chlorine generator you'll need, and you’ll want to get a salt chlorine generator that is easy to hook up to your pool.

Sizing

Here's the rule of thumb: your salt system should handle 1.5x to 2x the actual volume of your pool. This extra capacity ensures that the generator doesn’t overwork itself and provides consistent sanitation.

For example, if your pool holds 10,000 gallons, aim for a salt chlorinator that can handle between 15,000 and 20,000 gallons.

Pool and Plumbing Type

If your pool’s pump and filter is connected via 1.25” or 1.5” hoses or rigid plumbing, there are typically great options across many salt chlorine generator models. Many models come with slip fittings that glue to PVC plumbing connections. If your pool uses hoses that clamp, you can use above ground plumbing adapters to make your pool system widely compatible with many chlorine generator models. When plumbed, the salt chlorine generator is plumbed as the last piece of pool equipment before the water returns to the pool, after the pump and filter.

If your above ground pool doesn’t utilize plumbing, or if you simply wish to avoid the work of plumbing the chlorine generator in, you can utilize “drape over” models which mount on or hang over the side of the pool. Popular models include the Controlomatic Megachlor or Saltron Retro.

Other factors to consider when choosing a system:

Climate

The hotter the climate and the more sun that you get, the higher the chlorine demand of your pool and you’ll want higher sanitation power.

Pool Use

The more you use your pool or the more swimmers you have, the more sanitation power you'll need.

Environment

If your pool is exposed to heavy debris (like leaves, storms, etc.), this impacts how much sanitation is needed.

Maintenance Accessibility

Make sure the system is installed in a spot that's easy to access for regular cleaning and maintenance.

Taking these factors into account ensures that your saltwater system will not only keep your pool clean but also last longer with less effort on your part!

How do I convert my above ground pool to saltwater?

Converting an above ground pool to saltwater is a relatively straightforward process. Here’s what you’ll need to do:

Step 1: Balance the Water & Add Salt

Before you start converting your above ground pool to saltwater, it’s important to get your water chemistry in check.

Proper preparation starts with balancing your water chemistry—adjusting pH, alkalinity, and calcium hardness levels.

Balancing the water creates a solid foundation for your saltwater system to work efficiently, allowing the salt chlorine generator to continue to consistently maintain your pool's cleanliness.

By balancing the water before the switch, you’ll help avoid any hiccups in the transition, ensuring your pool stays sparkling from day one!

Add Pool-Grade Salt to Your Above Ground Pool

After balancing your water, it's time to add the salt. Since above ground pools don’t have deep ends like inground pools, you'll simply spread the salt as evenly as possible across the pool to help it dissolve efficiently.

For above ground pools, you’ll typically aim to add about 30 lbs of salt for every 1,000 gallons of water to achieve the target salinity level of 3,000 to 3,500 parts per million (ppm).

For instance, if your above ground pool holds 10,000 gallons of water, you’ll need approximately 300 lbs of pool-grade salt. Most salt comes in 40-lb bags, so plan on purchasing around 7-8 bags.

How to Add the Salt:

1. Spread the Salt Evenly: Pour in the salt across the area of the entire pool. Even distribution will allow it to dissolve quickly so the chlorine generator can begin working ASAP.
2. Brush and Circulate: After spreading the salt, use a pool brush to help push it around the bottom of the pool. This is an optional step that will help it dissolve more quickly.
3. Run Your Pump: Turn on your pool pump and let it run for 24 hours. This will circulate the water and help the pool water mix thoroughly, ensuring even salinity levels.

Will My Pool Taste Salty

Not at all! Saltwater pools have far less salinity than the ocean, so much so that it isn’t comparable. While seawater has around 35,000 ppm of salt, your above ground pool will only have about 3,000 ppm—so mild that most people won’t even notice a salty taste.

Choosing the Right Salt

Always use pool-grade salt with at least 99% purity to prevent introducing impurities like metals or minerals that can disrupt your pool’s chemistry or damage your equipment. Anything labeled as pool salt is a ready-to-go option. Otherwise, look for this purity level on the packaging and ensure there are no additional additives to make sure you're using the right kind of salt for your pool.

By following these steps, your above ground pool will be ready for its saltwater conversion, offering softer, clearer water with less manual upkeep.

Step 2: Install the Salt Chlorine Generator

After you’ve chosen the right salt system for your above ground pool and balanced the water, there are two main steps to get it set up:

1. Connecting the salt chlorine generator to your pool’s plumbing
2. Mounting and powering the system’s control box

Before you get started, gather all the necessary tools:

• PVC glue
• Primer
• Pipe cutters (or a hacksaw)
• Measuring tape
• A marker
• A screwdriver or drill

It’s also smart to have the system’s installation guide handy and ensure the power source is switched off for safety.

Connecting the Salt Chlorine Generator

The salt chlorine generator uses a component called a "salt cell" that gets installed into your pool’s plumbing system. It converts salt into chlorine as the water circulates, keeping the pool clean.

Here’s how it works for above ground pools:

• The salt cell is usually installed after your pool’s pump and filter.
• Cut a gap in the pool’s PVC plumbing to place the salt cell. This is where water will flow through the cell, allowing chlorine to be generated.
• Using PVC primer and glue, connect the plumbing unions to the cut pipe and attach the salt cell.
• Ensure all connections are tight and secure to avoid leaks.

For above ground pools, the process is straightforward and can be completed without the need for major alterations to your existing plumbing system. Just follow the instructions, and you'll be on your way to a saltwater system.

Even more convenient, some above ground salt chlorine generators eliminate the need for plumbing by hanging on the pool’s side such as the Saltron Retro or Controlomatic Megachlor.

Mounting the Controller and Connecting to Power

The control box manages your salt system, and it’s typically mounted nearby on a vertical surface such as a fence, post, wall, or something similar. You’ll either connect it to your pool’s timer or directly to the pump’s power source. This allows the system to work in sync with the pump, so chlorine is generated whenever the pump is running.

Most systems are compatible with both 120V and 240V power sources. Just make sure the voltage matches your pump setup to ensure smooth operation.

With everything connected, your pool is ready for salt!

Step 3: Set the Salt Chlorine Generator’s Output Level for Your Above Ground Pool

Now that your salt chlorine generator (SCG) is installed and your above ground pool’s chemistry is balanced, it’s time to fine-tune the system’s output level to keep your water clean without wasting energy or chemicals.

Start with Balanced Water

Before powering on your generator, double-check that your pool’s water is properly balanced. Ensure that your pH, alkalinity, and stabilizer levels are within the recommended ranges. This will help your SCG run efficiently from the start.

Power Up Your Pump

Once your water is balanced, turn on your pool pump. The salt chlorine generator should activate along with it. You’ll know it’s functioning when the "Power" and "Generating" lights turn green.

If a “No-Flow” light flashes, don’t worry—this just means the system is waiting for water circulation to stabilize. It should clear up in about 60 seconds once the pump is running smoothly.

Setting the Chlorine Output

To begin, set the chlorine output of your SCG to about 75%. This is a good starting point to gauge how much chlorine your above ground pool will need. Over the next 2-3 days, use a test kit or test strips to monitor the chlorine levels.

• If levels are too high: Decrease the output setting by a notch.
• If levels are too low: Increase the output slightly.

You may need to make a few adjustments in the first week, but once the chlorine level is dialed in, your system will maintain consistent levels automatically.

Seasonal Adjustments

Your pool's chlorine needs will change throughout the season. During hotter months or when your pool is in heavy use (like during a pool party), you might need to increase the chlorine output to keep up with the higher demand. When the weather cools down or the pool is used less, you can decrease the output.

Remember, by setting your SCG correctly, you’ll greatly reduce manual maintenance and keep your above ground pool water clear and safe for swimming all season long!

How do I maintain my above ground saltwater pool?

Maintaining a saltwater pool is a breeze compared to traditional chlorine pools—there's way less hassle. But you'll still need to stay on top of a few simple tasks to keep your water sparkling.

Set the Chlorine Generator

First, set your salt chlorinator to maintain the right free chlorine level, which helps sanitize your pool. Keeping an eye on salinity and pH levels is key, too.

The good news is that salt systems do most of the heavy lifting for you since they automatically provide consistent chlorination every day.

Check Salinity and pH Levels Weekly to Monthly

With digital testers or high-quality test strips, you can easily check your levels and make adjustments in minutes, ensuring your pool stays swim-ready. Salt doesn’t get used up, but if you get a lot of rain or drain any pool water, you might have to “top off” your salinity level.

Check Your Salt Cell Every 3 Months

Even if your pool water looks crystal clear, it’s a good idea to give your salt cell a quick check at least every three months. That’s because calcium can build up on the cell itself.

This is especially true if your pH, calcium levels or water temperature are on the high side(another important reason why you need to check pH and salinity monthly).

Start by turning off the saltwater generator and disconnecting it from the power source. Then, remove the salt cell from your system and inspect it for any white, flaky deposits on the metal plates—these are telltale signs of calcium buildup.

If everything looks clean, you’re good to go! Just reassemble and check again in a few months. But if you do spot buildup, it’s time for a little maintenance.

Follow all manufacturer directions, but cleaning your above ground pool’s salt cell looks a little like this. First, try rinsing off the cell with a hose. If the deposits are stubborn, mix a solution of water and muriatic acid (5 parts water to 1 part acid). Wear protective gear, like gloves and a mask, and pour the solution into the cell. Let it foam for about 10 minutes, then rinse thoroughly with a hose.

Remember, you don’t want to overdo it with chemical cleanings—too much acid can wear down the cell over time. Keep your cleanings gentle, and never pour leftover acid into the ground or pipes.

Make Sure Water Circulation is On Point

A common challenge for above-ground pool owners is figuring out the right amount of run time for their pool equipment. Too little, and the pool stays murky; too much, and you’re needlessly running up energy costs.

The pool pump’s job is to circulate water, letting the filter keep things clear and giving the salt system time to generate chlorine. If your system doesn’t run long enough, the filter won’t catch all the debris, and the salt system won’t produce enough chlorine to keep the pool clean.

A good rule of thumb? Run the pump and filter for at least 1 hour per 10 degrees of outdoor temperature—so about 8 hours if it’s 80°F. This varies by pump model and pool size, but it’s a reliable guideline to ensure your pool stays crystal clear and properly sanitized.

For maximum energy efficiency and circulation, consider a variable-speed pump. It’s an ideal upgrade for permanently installed, well-built above-ground pools, especially when paired with a salt chlorine generator to minimize operating costs.

Variable speed pumps not only save on energy costs but also help provide optimal water filtration, helping your above ground salt pool system work more efficiently while keeping your water sparkling clean.

How variable speed pool pumps save pool owners money

Clean Debris Out of Your Pool

You’ll also just want to make sure you’re regularly checking your pool for any debris or dirt that could make its way into the water.

Leaves, pet fur, and other debris can clog your system or introduce algae and bacteria. Regular cleaning keeps your pool in top shape.

Final Thoughts

Converting your above-ground pool to saltwater isn’t just about reducing maintenance—it’s about enjoying a simpler, more refreshing swim experience.

With fewer harsh chemicals, cost savings of up to $1,800 over three years ¹, and a more comfortable swimming experience, it’s clear why saltwater pools are gaining popularity. While they’re not entirely maintenance-free, the simplified care routine means you’ll spend less time cleaning and more time swimming.
