To decontaminate, you need to super-chlorinate or super shock the pool or spa water with granular chlorine (or substitute granular bromine or lithium for chlorine). Our goal is to maintain 20ppm or more of chlorine for 72 hours.
The Super Chlorinate Button. The superchlorinate button on a chlorine generator simply sets the chlorine output to 100% for a period of time, usually 24 hours or until the system is powered off.
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).
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.
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..
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.
The high dose of chlorine and dead algae spores suspended in your water will make it look really cloudy right after shocking. That's completely normal. Fortunately, you don't have skim all of it out by hand. Run your filtration system overnight (or for at least eight hours) until your pool water isn't cloudy anymore.
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.
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.
Superchlorination, also known as shocking or chlorine shocking, is the process of adding several times more chlorine to the pool than is normally needed so that the chlorine can "burn" through resistant compounds, chemicals, oils and strong types of algae.
Always superchlorinate your pool in the evening to prevent evaporation from the sun. This will let you get the most out of the process. DO NOT SWIM for at least 12 hours after superchlorinating your pool. Make sure to test the water before entering the pool to ensure the chlorine is between 1.0 - 3.0 ppm.
If using granular pool shock (Cal Hypo), use 3 lbs per 10000 gallons, for a complete shock that will kill anything in the pool. If using 6% liquid chlorine bleach, add 5 gallons per 10000 gallons.
1. Shock the pool with chlorine every day until all the green is gone (possibly 3 to 4 days). 2. Run the filter 24 hours a day and backwash every day until the green and then cloudiness is gone (usually up to 7 days, sometimes as long as 2 weeks depending on the filter).
Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.
To clear cloudy water, you may need to run the filter 24 hours for a day or so to expedite the clean-up. For sand filters, adding a small amount of Alum acts as a filter aid, and flushes out with a backwash. Both sand and cartridge filters benefit from a chemical cleansing, using a filter cleaner.
The green is probably iron. Don't add more chlorine. Add a quart or two of good sequestrant. Brush the pool really well multiple times and then add the sequestrant.
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.
To add salt, turn on your filter pump and add the salt directly to your pool water. Use a brush to help the salt dissolve and to prevent the salt from piling up on the bottom of your pool. Run your pump for 24 hours to help distribute the salt evenly throughout your pool.
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.
