If you find that your pool is cloudy, you can check out our ultimate guide to clearing a cloudy pool , but here are six quick tips to follow:. Skip to content Today you're going to learn how to shock your salt water pool In six EASY steps. Let's dive in! Quick Navigation Should you add shock to a salt water pool?
Should you add shock to a salt water pool? When should you shock a salt water pool? To remove algae. To remove chloramines. If so, that means the combined chlorine is too high, causing a build-up of chloramine. To remove contaminants. This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM. Only then should you introduce algaecide to get the best results. Chlorine when introduced separately combines with algae and kills it.
However, when free chlorine combines with algae, very little of it is available for combination with bacteria and other potentially harmful contaminants. When you test the pool, you may find that it is chlorine deficient. Hence, a good way to handle algae is to ensure that the pool is shocked and quickly raise the levels of chlorine to 10 PM or even higher. Algaecides surely kill algae but they work slowly. This is because they release ions that are positively charged. Make sure you check the directions for the right dosage for your size swimming pool.
Circulate the water for about 2 hours to ensure the flocculant is fully mixed in, then shut off your pump and let it sit overnight. During this time, the chemical will start to bind the particles together and settle them to the bottom of the pool.
In the morning, you should wake up to a nice healthy particle cloud at the bottom of your pool. Hook up your manual vacuum cleaner. If you have a cartridge filter , unfortunately you do not have this waste option and all waste will go through your cartridge, more than likely clogging that cartridge filter element and leaving it needing to be replaced.
We do not recommend floccing your pool if you have a cartridge filter unless you plan on replacing the cartridge filter element when you're done. Then you can go back and continue vacuuming. You may have to do this several times, depending on how much debris you need to vacuum. When you are done vacuuming the pool and everything looks good, we would suggest double shocking 2 to 3 litres of acid over a space of 48 hours and adding 2 to 3 cups g of granulated chlorine your pool to make sure ALL the algae has either been removed or destroyed.
There are some good algaecides which directly kill algae, though they are almost all a glorified combination of chlorine and acid. These algaecides may have to be added in large doses, and depending on the brand, can get expensive. Unless you're using specific black spot algaecide for a specific black spot issue, hydrochloric acid dosing and bumping up your chlorine levels should also do the trick.
You can add mL every week to prevent algae from growing in your swimming pool. Metals in your water can cause staining. Remember the old saying "An ounce of prevention is better than a pound of cure?
Keep your pool from getting sick algae! Keep your pool in top shape and algae-less by doing some periodic maintenance, it may be a bit time-consuming, but it is worth it in the long run. Don't have much time? Don't worry, it doesn't take too long if you follow our tips and tricks on how to test and fix your pool water. And probably one of the best ways to ensure that your pool water stays algae-free is to ensure that your pool filters are in top condition all the time!
By using this method, you're keeping it simple by focusing on chlorine and acid, while using your filtration system to bring it back to life. It tends to be a bit of a work-in-progress and can take 1, 2 or even 3 weeks, depending on the state of your pool, but it's definitely the easiest.
We also personally like to recommend keeping an algaecide on-hand year round for monthly dosage. If your pool is clear and balanced, an algaecide will do its part in keeping any green, black or mustard algae bay during a chlorine or pH fluctuation.

Physically cleaning the algae and then shocking the water with pool shock works just as well. The best way to use an algaecide, according to Pool and Spa Resources , is as a preventative and not a remedy for an existing algae problem. You should shock your pool regularly in the summer months, especially after periods of heavy use, and adding algaecide after shocking is a good practice.
Because the algaecide can cause a harmful chemical reaction if the chlorine level is too high, as it is directly after shocking, you should wait for the chlorine level to return to normal, which usually takes about 24 hours.
Copper-based algaecides are most common, but they tend to stain metal components of the pool, and they don't work well if the pH is too high. Quat and polyquat algaecides are good alternatives, but they aren't as strong and only inhibit algae growth instead of curtailing it completely. If you use a quat or polyquat algaecide without much success, try a copper-based one. The best defense against an algae problem as well as cloudiness and other sanitation problems is to keep your pool water balanced.
That means maintaining the pH between 7.
