Chlorine generators need salt to produce chlorine and can't do so if the amount of salt in the water is too low. The desired salinity level in a saltwater pool is between 2,500 and 3,500 ppm. Get a salt-testing kit from a pool supplier and check to make sure that the levels are within this range.
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.
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.
Why can't I get a Chlorine reading? If you test your pool water and can't get a chlorine level reading at all it may be due to very high chlorine demand. High chlorine demand is the inability to keep an adequate level of chlorine in the pool water even though the water appears to be balanced and properly maintained.
If your water's pH is too high, it hinders the chlorine's ability to efficiently clean the pool. A water pH level that is too low causes the chlorine to dissipate more quickly. Therefore you'll need to add more chlorine to accomplish the task.
"Shocking” refers to the process of adding chlorine or non-chlorine pool chemicals to the water in order to raise the "free chlorine” level. The goal is to raise this level to a point where contaminants such as algae, chloramines and bacteria are destroyed.
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.
Besides normal and good water balance, all you need for a salt water pool is a chlorine generator and enough pool salt to raise the level to the salt system manufacturer's recommendation. You will still need to maintain good water balance on a salt water 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. An example of when you would add fresh water is after a heavy backwashing cycle. pool, or use a home saltwater test kit.
If your total chlorine level is high, you will use a non-chlorine shock; if it is low, you will use a chlorinated shock. As a rule, you will need to raise free chlorine to 10 times your combined chlorine to hit what is known as “break point.” Therefore, it is good to deal with combined chlorine while it is still small.
Raise the Level of Pool Chlorine
Raising pool chlorine can be much easier than trying to lower chlorine levels. Simply adding chlorine in the form of chlorine tablets, granular chlorine, liquid shock or powder shock will increase the total amount of chlorine within the pool.
The recommended free chlorine levels should always be between 2-5 ppm, depending on the level of cyanuric acid in the pool as indicated in this chlorine/CYA chart. Low salinity levels reduce free chlorine.
Bottom Line. A little bit of extra salt in your pool doesn't generally result in any concerning issues. However, putting in excessive amounts of salt, resulting in salt levels 5000 ppm or more, can lead to corrosion of your metal pool equipment. Not to mention, having too much salt will also make the pool saltier.
3400 is the recomended high limit, but the readings on the panel are notoriously inaccurate. Generally it's better to have the level on the high side than low, so 3800 should be fine.
The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being optimal. Before adding salt to your pool, test the water to check your salt level. If the level is low, determine the number of gallons in the pool and add salt according to the chart below.
Instead of adding chlorine to sanitize a saltwater pool, you add salt, and then a chlorine generator converts it to chlorine. When the free chlorine level is low, that usually means it's time to add more salt, but it may mean a couple of other things as well.
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.
Answer: Partially drain the pool and add fresh water to dilute the salt levels in your pool. Don't forget to check and balance all of the other chemical levels in the pool as you're effectively diluting everything in your pool.
A saltwater pool is an alternative to a traditional chlorine pool. Although you don't add chlorine tablets to a saltwater pool, it does still contain chlorine. It just has a smaller amount that's generated through the filter system. A saltwater pool contains 10 times less salt than the ocean.
If your pool is truly low in salt, then you can add salt at any time, but you need to use external sources of chlorine such as chlorinating liquid to shock your pool to kill the algae; you can't kill the algae in a bloom fast enough with an SWG alone..
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!
Can you put too much shock in a pool? SKIMMER NOTES: It's unlikely but it could happen. It would take a lot of shock to really make the water unsafe for swimming. The best way to make sure you're safe to swim is to test your pool water and make sure free chlorine levels are between 1-4ppm for healthy swimming.
If using 6% liquid chlorine bleach, add 5 gallons per 10000 gallons. Add the Shock: With the filter system running, and the pH on the low side, 7.2-7.4, add the chlorine (granular or liquid) slowly to the pool, dispersing it around the pool edge, or broadcasting the pool shock over the surface.
Chlorine is a sanitizer, and (unless you use Baquacil products) is necessary for maintaining a clear and healthy pool. Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly.
Over-salting will not harm your chlorine generator, but it will lead to salty tasting water. If levels exceed 6500 ppm the chlorinator is programmed to protect itself by alerting the user that there are high salinity levels in the pool. To reduce the salt level, drain some water and refill the pool with fresh water.
