Using Bleach To Shock Your Pool

Bleach contains sodium hypochlorite , but at a lower concentration. The level of sodium hypochlorite in bleach is between 5% and 6%, while chlorine is between 10% to 15%.

What that means is that you would need twice the amount of bleach as normal chlorine. And to ensure that the bleach doesnt get degraded by the sun, you should add it late in the afternoon.

Do I Need To Add Other Chemicals

After using a shock treatment, its best to give your pool a break from other chemicals and use it for a couple of days. Shock will drastically change the chemistry of your pool and youll need to wait to test your water. Its important to adjust your pools water after a shock treatment because it will help to maintain your water and deter further algae growth. To make sure your pool doesnt grow algae anymore, try to keep your water pH around 7.3 and your chlorine levels at 1 to 3 parts per million. If you take these steps, youll likely never see algae growth again.

When To Shock Your Pool And How Often

Shocking your pool is not a one-time thing. It should be a regular part of your swimming pool maintenance routine. I recommend keeping a record or logbook near your pool to stay on top of this maintenance.

If you are operating on a weekly oxidizing and shocking schedule, you should alternate between a non-chlorine and chlorine shock each week. Following this system makes chlorine much more effective when it is implemented. Plus, it will lower the amount of chlorine required.

So what are some specific circumstances where you must shock the pool?

Rain and thunderstorms can contaminate the water with debris, dust, and excess rainwater. This is why you should always shock your pool after rain.

Algae outbreaks are also a key signal for pool shocking. When algae begin to appear, you should utilize a shock type with more chlorination to kill and remove the algae.

You should also make sure to shock your pool when you are opening and closing for the season. After you have balanced the other chemicals, shocking the pool will eliminate bacteria and make the water nice and clear.

It is also a good idea to shock the pool after hosting events where many people will enter the pool.

Turn Off Your Filter System

Another important step is to be sure to turn off your filter system. It doesnt matter if your filter is a sand filter, cartridge filter, or D.E. filter you need to turn it off before filling up your pool.

You dont want the dirt from the bottom of your pool being sucked right into your pump, which can cause severe damage.

Shocking a pool with liquid chlorine or a granular pool shock kills or inactivates pathogens and algae. Shocking will also oxidize other unwanted materials inhabiting the pool water.

    How Often Should You Shock Your Pool

    The frequency of pool shocking isnt set in stone, and it really only needs to be done when your water starts going haywire.

    Some things youll be able to visually see , but most water pollutants will be invisible.

    There are some pool owners who like to shock once a week to keep the water its cleanest, while others will do it on a 3-week or monthly cycle.

    Shocking frequency also depends on how much use the pool is getting, and what kind of weather its being subjected to. Heavy rainfall and storms can disrupt the pool waters chemical makeup by introducing backyard debris and air pollutants like dust and pollen spores into the water.

    Likewise, an increase in the number of people using the pool will bring in more organic bacteria, resulting in a chlorine level decrease. If you have a pool party, youll most likely have to shock the pool once its over.

    Youll also want to apply shock treatment when opening the pool, and closing it down for the season.

    On opening, after youve balanced its pH level, shocking will sanitize and oxidize the pool, restoring its clear water. On closing, pool shock is used as a disinfectant to prepare the pool for the winter months.

    Also of note, if you were wondering, you cant overshock a pool. The worst that will happen is the water has an abundance of chlorine for a few hours. Once the sun comes out, it will quickly destroy the chlorine and bring the pool back to a level that is safe for swimmers.

    Shocking For Algae Removal

    Its a generally accepted notion that 30 ppm of chlorine residual will kill all algae. Assuming that your pool is clean, and you have adjusted the pH, you can now add the granular chlorine to the pool.

    Most pool shock packages will list directions to add 1 lb. of shock per 10,000 gallons of pool water. That may be fine for normal conditions, but if you have a severe algae attack, a triple shock is needed. 1 bag will get reach 7-9 ppm, but for 30 ppm, you need 3, 4 or sometimes even 5+ lbs per 10,000 gallons of pool water.

    Shock it until the water turns Blue-ish, said Davy Merino, our blog editor. Thats what I do. A fine technique you do want to add shock to the pool until the water loses the green color, and turns a blue-ish gray color.

    Heres a chart that can be used with our Pool Shock and Super Pool Shock products. The numbers indicate the amount of shock, in pounds. You may need more to see the blue color begin to return to the pool.

    How much shock is needed to achieve 30 ppm will vary depending on the available chlorine percentage of the shock you are using. For example, if using In The Swim Super Shock, its a 73% cal hypo shock, but HTH Shock -N-Swim is only 45% cal hypo so youd use more or less, depending on the shock potency.

    Computing The Amount Of Bleach To Use

    Now you can know the gallons of bleach you would need to shock your pool as follows: use 0.5 gallons of Clorox per 10K gallons of water to increase the level of chlorine by 5 ppm.

    If you want to raise the level of chlorine by 2.5 ppm, then you would need ¼ gallon of the product per 10K gallons of water. You can use the above math to determine how much gallons you would need to use and ensure you continue to test the water.

    How Do I Find The Right Shock For My Pool

    There are four major types of pool shock, but my top recommendation is to use calcium hypochlorite, which is the most popular and for good reason: its effective, and its the most affordable shock on the market. Unfortunately, its usually pretty labor intensivesince its slower to break down, you generally have to pre-dissolve each pound in a five-pound bucket of water first. My solution? Skip that process entirely by using calcium hypochlorite that you can add directly to your pool, without pre-dissolvingand thank your lucky stars it exists!

    What Is Shocking A Pool And Why Should You Do It

    Shocking a pool, also known as pool chlorination, is adding chlorine in swimming pool water to sanitize itgetting rid of chloramine , contaminants, bacteria, preventing algae, ammonia, and other living organisms from thriving in your pool.

    Chlorinating a swimming pool is a very important and necessary part of pool maintenance.

    Every pool owner should at least understand how to do it, how frequently, what amount of chlorine to add, and which chlorine shock to use in a pool.

    Moreover, the cornerstone of keeping free chlorine active all the time is keeping it in proper balance with cyanuric acid.

    The higher the cyanuric acid level in your water, the more your free chlorine will be ineffective, and the more chlorine you will use in your pool.

    Confirm on Trouble Free Pool’s Chlorine/CYA Chart to know the correct amount of chlorine to add at a given level of cyanuric acid.

    By regularly adding chlorine shock to your water, you completely avoid the hassle of SLAMing your pool to clear algae and ammonia.

    To have a trouble-free pool throughout the summer, I always recommend the use of non-stabilized chlorine known as sodium hypochlorite with a 12.5% chlorine concentration for pool sanitization.

    You can also use sodium hypochlorite with a 10% chlorine concentration, but not a regular household bleach that comes with low chlorine concentration of 8% and below.
