This is all possible thanks to your pool's salt chlorine generator cell. With proper care, a cell will last about five years. Eventually, though, it will need to be replaced. The trick is, it's not always easy to know when it's time.
The safe answer is that they usually last for about five to seven years. Salt Cells cost between $200 and $900 to replace, depending on your chlorinator model.
Salt cells fail for a few different reasons, the main reason being lack of proper maintenance. It is very important to check the cell regularly for excessive buildup. Doing this ensures excess calcium doesn't become caked on the metallic plates.
The easiest way to ascertain if the chlorinator is working is to make sure the cell is clean by checking the needle or production lights. Ensure there is enough salt in the pool. On the chlorinator box there should be a light or dial that indicates it is working.
In pool water temperatures that are 60 degrees or below, the salt generators simply shut down and by design do not allow the salt cell to ionize (breakdown) the salt and convert it to chlorine.
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.

Generally, a salt cell lasts for about 10,000 hours, which is usually around five years for most home pool owners.
Coil a few wires around the salt cell and slowly submerge it into the solution. Soak the cell for several minutes. Pull the cell out of the solution with the wire and rinse it off thorough with a high pressure garden hose. Fit the salt cell back onto the system and plug everything back in.
The control board sends an electrical charge to the cell, and electrolysis occurs, which produces chlorine. Eventually the metallic coating on the cells erodes, requiring the cell to be replaced. A well maintained cell will last 3–7 years at an average replacement cost of $700–$1100.
Pros of Saltwater Pools
There's less chlorine and less of the heavy chemical scent and content. They're gentler on the skin, with less irritation to the eyes, hair and swimsuits. The water has a softer, silkier feel to it compared to chlorine water. They have lower maintenance costs than chlorine pools.
There is no set timeframe of when you need to add salt to your pool. Because salt does not dissipate from your water, the only time you would add salt to your pool is when you add fresh water or after heavy rain that dilutes salinity levels.
Inspect Cell LED or Fault Code - The inspect cell alert is not always a sign your cell is dead, but it is a tip-off that you need to clean the cell, or the water chemistry requires attention. On some salt chlorinator models, like the Hayward AquaRite, the Inspect Cell flashes after every 500 hundred run hours.
Water flow
The saltwater chlorinator needs a sufficient flow of water for effective operation. A dirty skimmer basket, clogged or dirty filter, and a clogged pump strainer, can cause insufficient water flow for the chlorinator to produce less chlorine.
When it's time to replace your salt chlorine generator cell, you can expect to pay between $700 and $1,100 for a new one. Most people find that they need to replace their cell every 3-7 years, depending on the quality of the salt used and how well they maintain their pool.
Overall, you need to run your saltwater generator and pool pump for at least 8 hours daily. Not running either of these long enough means not enough chlorine to sanitize the water. Remember, the pool pump needs to be running simultaneously with the chlorine generator for the salt cell to produce chlorine.
It is best practice to remove your salt cell during the colder winter months. By removing your cell, you limit the potential damage that may occur to the unit during cold or freezing temperatures. The cold water and temperatures can damage the plates and stop the salt cell from functioning as intended.
We suggest you start your salt chlorine generator at 50 percent output and run it for a couple of days, then check the chlorine level. In a balanced pool, a good chlorine level is 1-3 parts per million. If your chlorine levels are low, you can raise the percentage, and if it's high you can lower the percentage.
Shock your pool once a week with Salinity Surge Shock or Salinity Oxidizing Shock. Pool shock works as an added defense against bacteria and contaminants. With Oxidizing shock, you can use your pool after just 15 minutes!
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.
Lower pH by adding muriatic acid or sodium disulfide to the water, and raise it by adding baking soda (sodium bicarbonate) or soda ash (sodium carbonate). Check the total alkalinity of the pool water before raising pH. If it's near the acceptable range of 80 to 120 ppm, use soda ash.
One of the most important steps in winterizing your salt chlorine generator is to drain all water from the manifold assembly this includes the cell and tri-sensor. Some manufacturers encourage the removal of the cell all together.
An overly salted pool will generally not be a major problem (aside from salty-tasting water), but at levels over 6000 ppm there may be corrosion damage to some of the metallic equipment.
