A saltwater pool is not a chlorine-free pool. Salt chlorine generators offer an alternative method of sanitizing a pool by using salt to produce its own chlorine automatically. A saltwater pool works much the same way as any other swimming pool, but instead of adding chlorine tablets, you'll add a fine-grain salt.
Sometimes a saltwater pool's chlorinator isn't creating enough chlorine, and the water can become cloudy or develop algae. When this happens, a bit of chlorine can save the day, said Hunker. You can add extra chlorine to the pool through calcium hypochlorite, sodium hypochlorite, or chlorine tablets.
Many people use liquid chlorine (sodium hypochlorite) or solid chlorine compressed with cyanuric acid (granular or in tablets). In the case of a salt chlorine generator, you use salt (NaCl).
Yes, a salt water pool has a reduced cost of operation as compared to a traditional chlorinated pool. This cost savings is primarily because chlorine is generated from salt and there is no need to buy chlorine. Additionally, salt water pools require fewer chemicals to keep the water clean and clear.
Is a salt water pool better than a chlorine pool? In our professional opinion, YES! Salt water pools are generally lower in chlorine. The chlorine found in saltwater pools are naturally produced from salt, rather than adding harsh liquid chlorine (a.k.a bleach).
So, not only is shocking a saltwater pool okay, but it's actually important to your pool's health. Shocking is the process in which you overload your pool with chlorine (3-5 times the normal amount) to improve your pool's cleanliness and kill off organic matter.
Salt Water Pool Cost
Homeowners pay an average of $25,000 to install a new salt water swimming pool, compared to the cost of installing a traditional pool, which has a price tag of about $23,000 on average. Cost to build a standard, 20,000-gallon pool can be as low as $12,000 or as high as $67,000.
Salt water pools are most stable with a pH of 7.6, and Alkalinity of 70-80 ppm. A stabilizer level of 50-80 ppm is recommended by most salt system manufacturers. High calcium hardness levels have no effect on salt water pools, but a level of 180-200 ppm may result in less scale on the salt cell plates.
While green algae are endemic in salt water pools, they are the easiest to kill. Green algae tend to grow during summers when the temperatures can get high. They float freely in the pool, making the water green. You might even see them growing on the bottom of the pool, on the walls, or in the crevices.
To get rid of cloudiness, you will have to do a liquid chlorine shock to raise the level of free chlorine (since the chlorine produced by the generator is not enough; a chlorine generator just assists you in maintaining the level of free chlorine).
You can convert your chlorine pool into a saltwater swimming pool and enjoy the benefits of salt water chlorination right in your own backyard. If your pool has a traditional chlorine sanitization system, you can easily switch to Hayward's advanced salt chlorination system.
Chlorine pools are more traditional and are also cheaper than most saltwater pools. However, they can be more difficult to maintain over time. Because there is no generator making chlorine, you will need to add chlorine into the pool on your own.
You should review the salt cell at least every two months. Most need cleaning a minimum of every six months, and sometimes more often, so checking the cell is essential to make sure it doesn't need replacing. If you do have deposits, continue to the next steps.
If it's a saltwater pool, by all means, open your eyes. So long as you know perfectly well that the pool is clean and free of any bacteria or viruses.
While they do cost a bit more on the front end than a chlorine set up, the ongoing maintenance for saltwater pools is typically far less expensive. Generally, you can expect to pay somewhere around $300 to $800 a year on the chemicals you'll need to maintain a chlorine pool.
For most people, the big selling point for saltwater pools is, well, the salt! The lower-chlorine saltwater is better for swimmers' hair, skin and eyes. Additionally, it also tends to be less harsh on pool toys and swimsuits. So saltwater offers better longevity for your accessories.
Saltwater Pools Come With Health and Environmental Concerns
Providers have also linked higher heart mortality risks to sodium absorption through the skin, particularly among people with: High blood pressure.
You definitely need to drain some water from the pool when salinity reaches a 6,000 ppm level. Most salt water pools should be maintained with a salinity level of 2,500-4,000 ppm. The amount you drain depends on how elevated salinity levels are.
Shock also helps to raise the free available chlorine level of your swimming pool. How do you raise the free chlorine in a salt-water pool? You can use granular shock or shock pods in your saltwater pool. Just make sure that you use your long-handled pool brush to disperse any shock that settles to the bottom.
