After a shock treatment, it's recommended to wait until chlorine levels drop to 1-3 ppm, which typically takes about 24 hours.
Ideally, you should shock your pool at night, so the sun cannot interfere and destroy the active chemicals before they can do their job. Then, you can add your chlorine post-shock after the chlorine levels have fallen below 5 ppm.
What is your cyanuric acid level? Most likely, you aren't showing chlorine as it's getting consumed faster than you can add it. You need to get a cyanuric level reading. If it's less than 50, you'll need to increase it.
Unfortunately, you can't shock your pool using your regular 3-inch chlorine tablets. Common chlorine sanitizing products are great for maintaining chlorine levels, but not necessarily eliminating new waste, bacteria and algae.
Never mix hot tub chemicals unless instructed to do so by a specialist. Always add chemicals to water, never the other way around. Never add chemicals to your hot tub water while it's in use.
After NON-CHLORINE shock wait 10-15 minutes before entering. After chlorine shock it can take up to 24 hours to clear. Therefore it is recommended to use non-chlorine shock. It is always recommended to test with a PH strip again before entering.
No, you should not add shock and chlorine at the same time. The best thing to do is add spa shock treatment first and allow that to work, then test and add chlorine if needed.
A chlorine level between 10 and 30 ppm, sustained for several hours, is usually needed to remove severe algae, bacteria, and chloramines. Super Pool Shock can deliver 10 ppm per 10,000 gals from a 1-pound bag in good water conditions. If water conditions are poor, you may need more.
The quickest way to lower your sanitizer levels is by diluting the water in your spa. Grab a bucket and remove some of the water in your tub. Start with one or two buckets full of water if you are only lowering it. You may need to remove as much as half the water to make a difference.
Liquid chlorine and granular shock have the same active chemical that sanitizes your pool, what changes is the strength and the way you use it. Liquid chlorine is less costly, unstabilized and comes in liquid form. Granular shock is stabilized and comes in a solid form that dissolves in your pool.
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.
If there is too much chlorine added, wait for the chlorine to burn off after a few days or, for a more immediate result, partially drain the pool and refill it with fresh water. Is it possible to shock your pool too much? Yes—excessive shocking of your pool will keep it at an elevated chlorine level.
Bacteria, algae and microscopic contaminants, such as urine, sweat, sunscreen and beauty products, take a toll on your swimming pool's water chemistry. These substances, when present in your pool water, accelerate chlorine demand and can affect your chlorine's ability to maintain properly sanitized water.
Most shocks will take about 8–12 hours to work. For those using non-chlorine shock, 15 minutes should be enough to circulate the product and sanitise your pool.
It's best to add chlorine to your pool at night, so it can work while no one is swimming and the sun has set. If you use a slow-dissolve chlorine treatment like a tab, adding it at night gives it time to dissolve, so the pool will be ready to face the day.
In addition, keep your oxidizers (chlorine, shock, etc.) and acids (dry acid, muriatic acid) separated to avoid an inadvertent chemical reaction between the two. Also keep your trichlor chlorine tablets away from your pool shock. In fact, all oxidizers should be kept separate from other chemicals.
Can you over-shock a tub? Yes, you can indeed over-shock a hot tub by adding too much shock to your water. This is why it's so important to closely follow the instructions for application laid out on your purchased hot tub shock. Otherwise, you risk damaging the pipes and filters of your tub.
No, baking soda (sodium bicarbonate) is used to raise alkalinity, not lower chlorine. Why is my pool using so much chlorine?
The effect of excess chlorine in pools is an alteration in pH levels of pool water, making it more acidic. Signs of high chlorine levels can include itchy sensations in the eyes, nose and throat, nausea, vomiting, dizziness, lung irritation, and skin rashes.
Low chlorine levels often cause green or hazy water, so if your water looks a little cloudy and you haven't shocked in a while, adding shock is the first step. It is always best to shock the pool in the evening, when the sun if off the water. If not, the sun will suck it out as fast as you add it.
Once you have cleaned the pool, you should move on to the sand and DE filter. The expert says you should backwash them.
SKIMMER NOTES: Calculate your total pool volume first, then check the package of shock for dosing recommendations by volume. Typically for granular shock, you'll need one pound for every 10,000 to 13,500 gallons of pool water.
The best hot tub shock to use is dichlor. Dichlor withstands the heat of the hot tubs as long as you leave it open and is not used during the day if the hot tub is outdoors. This is because the sun dries up chlorine easily. The second best hot tub shock is a non-chlorine shock used with fluorine or chlorine sanitizer.
If you've got a floating dispenser, remove it before swimming. The chlorine levels around it could be higher and irritate swimmers. Also, it could be used as a toy by children or dogs.
The typical chlorine level in a pool should be between 2-3 ppm the aim when you shock a pool is to raise it much higher to over 10ppm which is guaranteed to kill any algae and bacteria that is in your pool water.
