How To SHOCK a Swimming POOL | Swim University

[@drdrew3]

This video is a great example of making a ridiculously easy task over complicated and potentially dangerous. With the pump running just cut a small hole in the corner of the packet and then drizzle it in around the edge of the pool. Keep the bag low so wind won’t redirect the granules. It takes about 45 seconds and all you need is scissors. Easy

[@Suntan38]

I have done the same thing for 20+ yrs

[@Skyking6976]

WTF…thank you. New pool owner and want it to be as uncomplicated and safe as possible.

[@KINGTITO316]

Facts this guy over complicating things lol

[@ni_wink84]

Yeah or just use liquid chlorine so you aren’t jamming your pool full of stabilizer and making the shock almost useless 🙄

[@duypham76]

So when I cut open the bag and fump it in different sides of the pool should be ok?

[@braddavis8552]

Matt is correct on this one. All pools need to be shocked or superchlorinated during hot Summer months on a weekly basis.

[@dannymeeusen]

I just bought a home with an above ground pool and this channel has absolutely saved the day. You guys are great, and myself and my family are VERY appreciative of what you've done here! Super clear and concise, very easy to follow having never owned/operated a swimming pool in my life! Thank you!

Grandular shock specifically says, "Do not pre-disolve".

[@twistandsproutmicrogreens]

Yep. Mine says that too.

[@laserbeam1620]

Not all say it

[@SwimUniversity]

Remember, some shock says NOT to pre-dissolve on the package, so always follow your brand of shock's directions. And if you want to know when to shock your pool, check out our other video here: kzbin.info/www/bejne/aaOap2aJZtiFqLc

I use this method and it takes to the water way better.

[@guillermosalce6236]

But the package says do not pre-dissolve ....

[@mrrobvs]

It depends on the type of shock. Check the ingredients. Usually, calcium hypochlorite (cal-hypo) gets pre-dissolved (which makes it extremely annoying to use). From my knowlege, trichlor and dichlor do not need to be pre-dissolved. Just cut a hole in the bag and pour it in with the mentality of "i'm gonna pour so little in this spot that it dissolves before it hits the bottom." Or just go buy some bleach or liquid and save yourself the trouble of adding other stuff to your pool.

[@jaybee3679]

I literally just said this to my mom lol

[@mc-cockpot5791]

hmmmmm….then dont

[@TomWilson8003]

Im looking at Poolife Turbo Shock 75% calhypo and it says in the package DO NOT mix with water - just add to your pool. This is an old vides so maybe things have changed. This video appears inaccurate for Poolife calhypo

[@buckethat_nino]

On the shock treatment I use it says NOT to pre dissolve. Is this a preference?

[@andreaardemagni6401]

Isn’t it better to use liquid chlorine? Just curious …

[@lovelylyfe932]

How will happen if I put more chemicals plus shock in the water at the same time. ?

[@Sonikbytes]

Sorry, had to chime in: dissolving super-concentrated 'trichlor' shock in a bucket is not very wise and somebody could end up in the hospital- happens all the time. Better just put in a skimmer with a pump running, This video will not tell you the level of the chlorine in PPM needed to shock the pool used by pros. (should be around 10). And of course there are different kinds of shocks on the market for different pools types and applications

[@drdrew3]

NEVER put highly concentrated chlorine such as shock directly in the skimmer. It should first be diluted by diluting it in the 15,000 gallon pool. You won’t have a problem right away but soon enough your plumbing will fail.

[@joelexis8887]

Is liquid shock just as effective or do I want to buy it in powdered form then mix it in water?

[@courtneypope8979]

Why at night ?

[@ronotardo]

Can i just walk around the pool slowly sprinkling the pool shock directly into it? and avoid using a bucket?

[@drdrew3]

Yes. You are doing it the quick and easy way. This video makes a project out of a 45 second task.

[@bw536]

When I shock it..should filter setting be on recirculating? Or filtration

[@johnw274]

Run the filter as you do normally. If you have a timer set it to cut off after 8 hours. If no timer it won’t hurt to run it till you wake up

[@vishp8151]

Is it okay to add the shock through the skimmer while the filter system is running on the re-circulate position while adding the pool shock.?

No

Filtration if you are shocking to get rid of algae because your going to want to filter out the dead algae.

[@aysede11]

Do you have to get out the chlorine tablets before using the shock? Or can you leave it

[@blakeeiu]

I'm curious as well. Should have turn off my autochlorine feeder while shocking?

[@drdrew3]

Doesn’t matter

[@livinginhorror5679]

How do you know how much to shock your pool if there’s less than 5000 gallons of water in it

[@madeleinefinley96]

Hi! I have dead algae in the bottom of my pool, and can't get it out. My pool is crystal clear, and then i will walk around in it, and the algae disperses and causes the water to get cloudy. I've shocked my pool a bunch using hth shock, and still have my chlorine tabs floating around. (my pool is a 13' round summer waves easy setup)

[@jodileaedwards6869]

Me too

[@alexalopez7239]

A chemical will not rid the algae. If the water is cloudy then you would use a flocculant to get all of the algae micro particle to fall to the bottom (clear water) which is where you currently are. The only thing left to do is to vacuum all of the algae that has not settled on the bottom. That's the only solution for your current problem. Hope it helps :)

[@drdrew3]

Add clarifier then brush vigorously to suspend algae. Run filter until it clogs and then rinse. Pump will need to run 24-36 hours and brush several times but then the water will be clear

[@bikesandbeats4693]

No explanation of exactly how much shock to actually use based on current chlorine and cya levels and how to test if the chlorine you added actually reached shock level? 🙄

[@carijames1981]

When I was a kid, my dad used to shock the pool this way, pouring it in a bucket, dissolving it and pouring it in my husband and I just got our first pool this year and we started pouring the packet directly in the pool. We quickly learned that it is a lot harder doing it that way because you have to then take the brush and brush all around the pool staring, the shock up better because when we just poured the powder straight in the pool, a lot of it would float to the bottom and sit in that will stain your liner and it’s not effective that way. To each their own know some people prefer to pour it straight in the pool but if you want it to be an easier job, dissolve it in a bucket first. My dad went to pull professionals when we got our first pull as a kid and asked every question about how to take care of it, and that is what they taught him.

[@ezzlon3241]

So is chlorine tablets or shock better

[@SwimUniversity]

They serve different purposes.

[@applepie2190]

This technique work perfect for my pool was a little green then 4 hours past then it turn to a foggy blue after running the pump for 24 hours it's Cristal clear😊

[@kennymacdowell1257]

Just pour shock around the edges on an inground pool. place tabs on the white steps (not ladder). If tabs sit on a liner they will fade spots on the liner. A chlorinator like Rainbow is the best way. A floating tab holder is great too but usually ends up in front of the skimmer. Tie a string to the floating tab holder and tie the other end to the edge of the pool to prevent it blocking the skimmer. And NEVER dump shock or put tabs in the skimmer!! NEVER!!!!

[@anitabiernaski8775]

so does ur pump have to be on filter or recirculate?

do you add pool shock daily? or ounce a week?

Every few weeks. Wherever you bound chlorine starts to appear on the water test.

[@akeavid]

Hey tnx for the vid .. I do think though that more stress shoujld be put on the reason, the DANGERS of adding water to a bucket containing 'shock' chemicals .. A near-explosive reaction could occur requiring hospitalization, or worse ... Another point might be: just wheN and how often does one do this chore?

[@AndrewStravitz]

If the water is in the bucket is pretty safe. If the water is poured on chemicals, that could be dangerous.

[@kennymacdowell1257]

An explosion?!! 😂😂😂 Adding water to chlorine powder can splash the chlorine on you, cause the powder to cloud and you breathe it, and some granules may clump in the bottom and not dissolve. Pouring the granules directly in the pool all the way around the edges is just easier. But be careful of wind direction.

[@TommAceAZ]

Hello Matt, sorry to bug you but have a question regarding running a pool vac when shocking. I know you suggested shocking pool at night but out her in AZ I run pump at night and run pool vac in order to clean and save energy use off peak hrs. So is it ok to run the pool vac as well as Skimmer when shocking the pool? Thank you for your time.

[@drdrew3]

Yes. You want the water circulating for a few hours after shocking - so skimmer and vacuum both ON.

No!! Never put tabs or shock in the skimmer. Sprinkle around the edges with shock. Tabs should be in a floater tied to the edge so it doesn’t end up blocking the skimmer.

[@flz9231]

What is whuter?

[@dankelly]

Do you need to leave your filter pump on overnight?

[@drdrew3]

8 hours is sufficient

[@ni_wink84]

Don’t use stabilized shock if you use tablets. In fact don’t use tables at all, use liquid chlorine and dose CYA yourself, Make sure you know your CYA level before you shock with cal hypo or other stabilized shocks, send your pool into chlorine lock and it’ll stay green no matter what, best method is use liquid chlorine to shock your pool, no mixing, no mess, no stabilizer to ruin your water

[@samxoxo5520]

After I put the shock I always brush the pool to let it circulate better. If you are using liquid shock, make sure you don't get it on your clothes b/c they will get ruined.

[@Viralclown]

I don’t get the shock. Shock packets here are the same dosage as chlorine buckets doesn’t make sense

[@drdrew3]

No. Liquid chlorine is only about 12% concentration (88% watered down)

[@kevinmatechak852]

hey I have an 18 foot round above ground pool and I use 3 inch pucks in a chlorinator and my cya acid is high I wanted to know is there a better chlorine to use for my pool? do all 3 inch pucks have stabilizer in them? my wife bought this Hayward chlorinator so if I can still use it I would like to cause it does make it easier then adding chlorine everyday

[@AndrewStravitz]

Pool shock does not contain cyanaric acid.

[@drdrew3]

Liquid chlorine does not contain stabilizer. After a few months of using it your CYA will slowly return to acceptable levels. Then you can start using pucks again but sparingly. That’s what I do. Then start shocking with 1 gallon liquid chlorine weekly. Use a non chlorine shock about 1 lb packet monthly when bound chlorine starts to appear. The mechanical aspects are even more important than the chemicals. Clean filter every 2 weeks, skim and empty baskets every few days, brush weekly and keep that pump running 8-10 hours. Every pool is different but once you get a routine it’s quick and trouble free

[@818richardrajic]

When you shock the pool do you leave the pool pump on over night or off? :/

[@AndrewStravitz]

Let it run overnight

[@julioochoa2583]

Guys make sure the shock are disolve very good because after couples months or after 2 years you will see your pool liner more and more decorations and the bottom of the liner go white fast and dried the liner , We replace our liner this year after used shock in our pool Do your own tes disolve the shock and get glas and full with this mix shock and water and you will see wath happens All closin go to the bottom and drie your pool liner

Always do twice the recommended amount. Unless your pool is green then go 4x

[@6977warrior1]

Just use sodium hypochlorite (about 12.5% to 13%) liquid shock. Works better, faster and no premixing, no staining of liner from unmixed particles etc.

[@memegosha2326]

What's that

[@bwebsclips]

People say not to pour Hth into skimmers. WHY. I've always done this, for 30 years. I dissolve it in a bucket and pour it into the skimmer. It goes through the filter, cleaning it out and goes straight back into the pool, spread out across it. It goes blue very quickly. I then add the cyanuric acid the same way. WHY SHOULDN'T YOU DO THIS. Mine is a parapool with the same liner for 30 years, and the same filter system.

[@lakshmandalpadado9066]

Apperently the high concentrate chlorine damages rubber items in the pump/filter system. Always put in the pool to dilute.

[@jamesb8488]

I add in through skimmer aswell if I am doing one shock I'll just pour out in the skimmer without filter. For full cycle let the jets do the work.. liquid chlorine should be added on the outside border of the pool all the way around. Aswell as calcium chloride

[@AndrewStravitz]

Never put chlorine in skimmer. Cynaric is ok.

[@erickimmy1493]

What about a salt water pool? A guest at my hotel took a crap and I just had it open first time in 3 months. Going to back splash it and shock it in the morning. Do I still pre dissolve with a salt water system? Or just directly dump the 1 pound bag In the pool, and how long exactly until I can safely say they can return

[@jamesb8488]

It's much easier to take the filter cartridge out... Reassemble your filtration system without the filter. Take the shock packets and dump them into the skimmer next to the pool let the jets do the work for about 3 minutes. Then replace the filter. That's how I add in most chemicals except calcium chloride......

[@DigitalAndInnovation]

I am not so much up to date with this- but I am curious about the idea of carrying this out blindly. In general wouldn't a pH test be done before and after? Or is that not really the protocol these days if the correct amount of shock is put in and the time is waited?

[@gayle-aka-ideaswoman]

Why at night time? Because you cannot swim or another reason?

[@racheldodds9607]

Because UV light breaks down chlorine. It just gives it more time to be effective at night.

Taft Tinnin if the bag is good for 10,000 cut that in half an that gives you 5,000 but since your pool is 3,000 I'd put about half from the 5,000 from the first half. hopefully that makes sense.

That is exactly what happens when your CYA is too high - all the chlorine gets bound up instantly and rendered ineffective. Test your stabilizer level - sounds like you are locked up. I’ve had it happen from using 3” tablets

Why at night??????

[@erickrhernandez1451]

Should I net, vacuum and brush my pool first before shocking my pool?

Yes. Vacuum and skin before adding shock. Sanitizer is more effective AFTER organic debris is removed from the pool. And brushing suspends the algae particles into the main body of water where they are more vulnerable (compared to the pool surface).

I’m in Texas with a salt water pool and we use Leslie’s salt compatible pool shock bags. They say just cut bag open and pour in and it’s done. I don’t get this video- maybe because it’s not salt water??

[@SwimUniversity]

Depends on the type of shock you bought. Some can be added directly to the pool because they dissolve faster. And if you have a concrete pool, it's no problem either way. If you have a vinyl and the shock doesn't dissolve, it won't mix properly and bleach your liner.

[@eastwestmommy9001]

Swim University I see We have a gunite/plaster in ground pool.

[@uptownphotography]

Do you think there is any advantage to buying granular shock using 73 percent available chlorine over 65 percent available. Leslie Pools sells both types in 50LB Buckets and wondering if it's worth the extra $15 to $20. (depends on sale they're having the price difference). Thanks...Philip

[@Bugg7354]

Can it be any type of shock??

[@tr3slech3s]

If you have one 5 gallon bucket of shock, how much scoops do you put in the 5 gal bucket of water? I have a scooper

[@DadBooom]

1 lb, typically one "sock"/bag of shock. How much water you mix it with (i.e., the size of the bucket) doesn't really matter as it'll further dilute into the pool water. You premix it to help avoid it damaging your pool liner (which can happen from applying the shock directly into the pool)

[@shannonsweeley237]

How much shock do you put in a 1,185 gallon pool?

[@bmoreblondie6301]

Thought you are never ever supposed to pour shock into a bucket with water . thought its always spose go right into pool ??

[@SwimUniversity]

Depends on the type of shock. Fast dissolving shock can be added directly to the pool. And if you have a concrete pool, you don't need to pre-dissolve in a bucket because you don't have a worry about bleaching a liner.

But if the shock says don’t desolve

[@SwimUniversity]

Then you can follow it. But they say that to protect themselves. Makes sense. If you find shock that doesn't require pre-dissolving, then use that. It's out there. But not all shock products are the same.
