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.
When the chloramine level is 0.3 ppm or higher (just a bit darker on the Total Chlorine test), it's time to shock the pool – to remove the buildup of combined chlorine.
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.
Add 1lb of Saltwater Oxidizing Shock for every 5,000 gallons of pool water.
As shocking has a tendency to push metals out of solution and salt (even when labeled as pure) can contain trace amounts of metals, it is recommended that you add salt at a different time from shocking.
In this case, you should double shock your swimming pool water. To double shock, you will need to add 2 pounds for every 10,000 gallons of water. For instance, if you pool is 20,000 gallons, you will add 4 pounds of shock.
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).
For safe swimming conditions, the ideal salt level is going to be between 2500 ppm and 4000 ppm. 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.
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.
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.
A pool filter should be run for a minimum of 6 hours after shocking a swimming pool. This is to allow the filter to clean the water and give the shock enough time to fully mix with the pool water. Running the filter after shocking for 24 hours to 7 days is necessary if the pool has a large amount of algae.
What happens if too much shock is added? You cannot overshock a swimming pool or add too much. Adding too much shock or overshocking your pool will kill off algae. The negative of adding too much shock is it will upset the chemical balance of your pool.
Neither will chlorination be effective with a diffuser and without a pump. The best thing to do is to apply liquid chlorine in the pool. Then, you have to circulate the pool manually with the use of a telescopic pole or paddle. This will ensure the chlorine disperse well.
Wait until the shock process is complete, then put in the salt. It'll dissolve right away and be ready for the SWG by the time you get ready to use it.
It's recommended to wait at least 20 minutes to swim after adding salt to your pool. If you're adding calcium chloride to your pool water, it's recommended to wait two to four hours before swimming again.
Salt is usually needed due to loss because of backwashing the filter, bathing suit drag out, water splash out, leaks, or rainwater overflow. The AutoPilot's patented Tri-sensor is designed to let you know when and how much salt to add when it is low on salt.
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. What is this? Remember, the pool pump needs to be running simultaneously with the chlorine generator for the salt cell to produce chlorine.
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.
Annual booster additions of pool salt are usually required, but only to replace salt lost from backwashing, splashout or lowering the water for winter. If you fully drain the pool for maintenance, you will need to replace all of the pool salt.
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.
