The Best Salt Water System for Above Ground Pools in 2024

Monday, 19 February 2024 / Published in Swim University

The Best Salt Water System for Above Ground Pools in 2024

Salt water above ground pools are usually easier to maintain and use fewer chemicals than traditional chlorine pools. Whether you want to convert your existing pool or add a salt water system to a new pool, there are a few things to keep in mind:

  • Buy a salt water system that’s 1.5x your pool size. If you have a 10,000-gallon pool, you’ll want to purchase a system with at least a 15,000-gallon capacity.
  • Make sure your pump can handle your new salt system. Check with the manufacturer to see what pump requirements they have.
  • Purchase from a reputable company. If you need to replace or repair any part of your system, you’ll want a company that has available parts or a warranty.

With that in mind, we recommend the Hayward Goldline AquaTrol Salt System. Hayward is a well-known, reliable pool company that’s known for manufacturing consistently dependable pool equipment.

The Intex Krystal Clear Salt Water System is available in a variety of sizes, with options for pools as small as 2,200 gallons and or as large as 15,000 gallons. It features a 24-hour automatic timer for fully automatic operation, so pool owners don’t have to worry about running the system too much. Adapters are included so the system can work with both Intex and non-Intex pool pumps and filters, including sand filter pumps. However, it requires a pool pump with a flow rate between 700 and 3,000 gallons per hour (GPH). So make sure your pool is equipped accordingly.

What to Look for in a Salt Water Pool System

Here’s what to consider when buying a salt water system for your above ground pool.

1. Pool Size vs. Salt Water Generator Capacity

You will need a salt chlorinator with 1.5x to 2x your pool’s maximum capacity. It’s much better to get a larger system than your pool to ensure you have adequate sanitization power. For example, if you have a 20,000-gallon pool and use a system that has a maximum output of 20,000 gallons, you risk overworking your system and burning it out.

2. Chlorine Output

Your salt water system’s chlorine output is measured in pounds per day. And opting for a system with the capacity for a higher chlorine output allows you to keep your water adequately sanitized. It also should let you turn down the system when you need to reduce the sanitization, putting less stress on your system. And if you need a higher output, like after a storm or party, you can crank it up higher as needed. If you’re constantly having to run the system on the maximum output, that’s a sign you might not have enough capacity.

3. Frequency of Pool Use

If you frequently have a lot of people in the water, you’ll need a stronger system. More people means more contaminants, which means you’ll need a powerful system to sanitize your water. Being able to turn up or down your chlorine output helps here.

4. Climate and Environment

If you live in a hot climate, you’ll need a stronger system (especially if your pool gets heavy use in the summer). That’s because heat and sunlight can affect your water chemistry. And if you have lots of plants around your pool, you’ll have more dirt, debris, and bacteria in the water that needs to be cleaned. That means a bigger system. Finally, if you live in a place where heavy rain is frequent, you’ll need more sanitation power. You’ll also want to check the salinity level more often, as rainwater will dilute your salt concentration.

5. Pool Frame and Equipment Compatibility

If your pool has a steel or aluminum frame, do not use a salt chlorine generator system since it will cause corrosion. Other materials, such as vinyl and resin aren’t as susceptible to damage from corrosion. You may be able to replace components with more salt-tolerant pool equipment. Also, check to make sure that your pool filter and heater are compatible with a salt water system.

How to Convert to a Salt Water Pool

Have an above ground pool that you want to convert from a traditional chlorine pool to a salt water system? It’s actually easier than you may think and it doesn’t require any draining.

1. Check for Compatibility

Check to make sure that your pool filter, heater and pump are compatible with your system. While you do not need a special kind of pool pump for a salt water system, it needs to have enough capacity to support your new generator. And remember, a steel or aluminum pool frame will corrode with a salt chlorine generator system.

2. Balance Your Pool Water Chemistry

The good news? You don’t need to completely drain your pool to convert it to salt water. Check your generator installation manual before adjusting your chemicals. But in general, here’s the recommended water chemistry:

  • Free chlorine: 1 to 3 ppm
  • pH: 7.4 to 7.6
  • Alkalinity: 100 to 150 ppm
  • Calcium Hardness: 175 to 225 ppm (don’t worry about this level if you take down your pool every year)
  • Cyanuric Acid: 30 to 50 ppm. Salt water pool owners may find that running CYA levels up to 80 ppm is helpful for keeping free chlorine levels where they should be. But you can always add more later, so start slow.

3. Install the Chlorinator

You’ll first need to mount the chlorinator controller to the wall near your pool’s equipment pad. Then, wire the controller for power. From there, you’ll connect the generator cell to the plumbing, then connect the cell to the controller. Always follow the manufacturer’s instructions for installing your generator so you don’t void your warranty.

4. Add Pool-Grade Salt to the Water

Your generator won’t start working until you add enough salt to your water. The amount of salt you’ll need to add is based on the water volume. Your generator’s instruction manual should provide a table to help you determine how much salt to add to the pool. But if you need more help, check out our guide on How Much Salt to Add to Your Pool. In general, you’ll need about six or seven 40-pound bags for a 10,000-gallon pool that has no salt in it. Be sure to purchase pool-grade salt.

Frequently Asked Questions About Above Ground Salt Water Systems

Need more help finding the best salt water pool generator? Here are some common questions and answers.

How is a salt water pool different from a traditional chlorine pool?

A common misconception is that salt water pools don’t use chlorine. But a salt water pool is actually still a chlorine pool. The difference is that a salt water pool uses a salt water chlorine generator to convert pool salt into chlorine through electrolysis. The result is a consistent chlorine level with no need to constantly add chlorine to your pool. The resulting salt in the water is similar to the amount of salt in human tears. That’s about 3,500 parts per million (ppm).

Can you use a salt water system in an above ground pool?

Yes! All that matters is your pool is made out of material that can withstand the salt and that you have a salt water generator designed for an above ground swimming pool. There are systems available specifically for inground pools, which are not used interchangably.

How do I convert my above ground pool to salt water?

After you choose the salt water chlorinator system that is best for your needs, simply adjust your chemicals, install your system, add pool-grade salt and turn on your generator. For a complete step-by-step walkthrough, check out our guide on How to Convert Your Pool to Salt Water.

What equipment is needed for an above ground salt water pool?

All you need is a salt water chlorine system (which contains a control box and a salt cell). In terms of other pool supplies, you’ll need pool-grade salt to add to the water.

How much does a salt water pool system cost?

For an above ground swimming pool, a salt water pool system can be as little as $300 or as high as $2,000. Installation costs vary, depending on location and the size of the pool.
