Get the video course. Absolutely worth it. I ditched my pool guy and have been following this program for the last two years and my pool chemistry and water has been fantastically maintained. I’m too lazy to clean my DE filter so I get a pool guy every six months to do that. Saved me thousands of dollars.

This is good channel. This is my first year with a pool. I've always tested in acceptable parameters since we opened thanks to these videos.

You are awesome. I am learning so much about how to care for my pool through you. This is my first pool so thanks and keep ‘em coming.

Been checking out all your videos, very helpful and informative. Thank you. Also enjoy your humor and presentation.

With being a novice to the inground pool community, your videos help us so much! The pool company ran through all of this upon opening/ cleaning our pool, and of course I've forgotten everything LOL, so needless to say your pool tutorials are a life saver! SUBSCRIBED!!! Thank you so much for this!

Nice video! Excellent explanations. Very helpful. Keep ‘em coming!!

Great video! When shocking your pool should you turn the In-line chlorinator off? I notice when i add one bag of shock to my 15,000 gallon pool it take several days before the Free Chlorine gets back down to 3ppm

thanx for all your videos, your suggestions are simple & work 👍🏻

Love your videos! First time pool owner here.. Would you recommend using a chlorine free sun shock (copper rod) instead of "chlorine shock"?

I've watched enough of your videos and I'm ready to make a purchase but do I need to get both your handbook pool subscription and also the spa/hot tub or does 1 cover both. I'll make my purchase as soon as u answer me. Ty u in advance.

Thanks a Lot, very easy ti understand

Smart man. Knows how to market his craft. I like this guy.

Learned a lot.... Thanks!

In general, can I use sodium hypochlorite as a shock if I normally use muriatic acid to reduce pH? I know they should never be mixed together or added at the same time.. but I want to know if I'll have any issues long term by using them in my pool. Your videos are great very helpful

This is the best and most straight forward video I’ve found about pool shocking. Although, I don’t agree with everything, for example, I live in Tampa bay, the US capital of lightning storms. If I followed rules 5 (at 3:15, shock after a heavy rain) and 6 (at 3:26, shock after extremely sunny or hot weather), I would have to shock the pool almost every day starting from mid Spring to the end of Fall, lol.

Thank You!!!

quick question... when I shock my chlorine level is still high for days after including use and rain.. should I add maintenance pucks or am I good too go till it lowers

Thanks. You're to the point. Always correct. Saved my pool. And 100% on the money!👍

Thanks for the video! Do I need to remove my suction-side pool cleaner during the shock? If so, I imagine I need to completely disconnect it from the pool wall and leave it out so that it doesn't try to run when the filter is on right? I appreciate the help.

In the process of learning pool care because getting an Intex here very soon. It's just a small pool, 12' x 30in. Still researching so any info would help. My understanding is if using non chlorine shock, you need the chlorine tablets but what about if using chlorine shock, would I still need to use chlorine tablets?

Great Show 👍😎🤝

Thank you. I will clean the filters and run the pump longer. I can’t vacuum to waste because the of the cartridge filters I can only take them out and hose them down. Would a clarifier help or more liquid chlorine?

Can you recommend an all around good pool testing kit? Maybe something a little better than those strips? Thanks!!

Do I still need to shock weekly with a salt water pool?

I bought XtraBlue Algaecide 40 oz. Algae Prevention and Algaecide and Xtra shock. Can I put them both in at the same time

i bought an ozone pool with a hayward cl200 chlorinator , was told my free chlorine levels should be at .5 ppm ? i have slim developing on sides and bottom should i shock it? also is there a video or tutoral on how to operate my pool thanks

When would you use non chlorinated shock and other than not raising the chlorine level, does it serve the same purpose? (I do have a salt water pool but prefer to use the granulated shock over the generator 😉)

Hello Swim University, I have a SWG Intex pool, 14,364 gallons. I have a SWG that came with the pool(it produces 11g of chlorine/hr) and it has a "boost" mode where it simply runs the chlorinator for 36, 48, or 60 hours. My question is this, is running the boost mode weekly going to obtain a similar result as the traditional shocking method(of putting a large amount of chlorine into the pool by adding bags of shock)? If so, then I have a follow up question. I would like to use this boost mode to shock my pool if possible(since it wouldn't require me buying bags of chlorine) but it seems impractical to boost my chlorinator which takes 36 hours to do(and me not being able to use it due to elevated ppm levels), and THEN once the chlorinator turns off to wait even more time for my free chlorine numbers to go back down to 3ppm. I would lose almost 2 days of swimming every week, unless i'm calculating something wrong. What would you do if you were me and wanted to use your pool almost daily? thanks.

Will this work on a above ground pool it's a 18 x 4.9 inch swimming pool above ground

Hello Matt I been watching your vids , now since I purchased my pool so can you please make a informative VIDEO ,on how to actually to shock out the COMBINED CHLORINE not 1 video on KZfaq you will be the ONLY 1 each step after you get your FC, TC, & then CC , how to find out on how much shock you actually need to RID THE CC, I hope you read this thanks.

Did you say mix in pool water? Want to make sure ☺️

Can you do a video unless you have one already that explains everything to do after your pool is installed and pool has water- for a Day 1 after install new pool owner

How does shock and keeping your pool clean videos apply to a pool with Perma salt system?

After adding shock the next day I noticed a small increase in the de filter presure gage. Is normal to see?

Thanks for this video .what I need to add or check after finish filling the pool for the firsts time ?

I used a 54% chlorine shock is that ok? do you just use more?

Hi! Cheers from Panama in central America, ok right now we are in summer and every day the sun is very 🔥 HOT 🔥 How should I shock my pool? I have a 18 x 48 intex above ground pool, I'm adding soon a 2100 GPH sand filter pump, had to empty my pool since it got green and I did a clarification and all the Algae when to the floor but the pump I have right now that is a cartige filter did not have the strength to pull that algae out.. so I don't want to go though emptying my pool again.. please help

New pool owner once I fill my pool do I shock it ????? Also I’m going to be using chlorine tablets in a floater adding weekly do I still shock ??? If so do I use non chlorine shock or with??

What is better? Liquid shock from the pool store or the kind in the bags?

Hi thanks for the video, if my shock tablets is chlorine free, do I put chlorine straight away after I shock it or leave it for 8 hours ?

It is the same procedure for a above ground pool with vinyl walls ?

Do i back wash before or after shocking the water?

Nice!

I shocked our salt water above ground pool last night with pump filter running woke up and it’s green. What I do now I did everything as I should.

I live in California Kern county desert area so should I shock my pool after 100+ degree days

I have been shocking at night but I have an auto cover. Should I leave it uncovered for a time after shocking?

how much (ppm) of chlorine normally.... and how much when shocking?

I have noticed that the little granulars do not all dissolve in the bucket, will the hurt my pool liner if it stays on the bottom? Thanks for all of the Great Videos.

How can I treat white mold?

My pool water is Green and can't seem to get it clear after a bag of shock. I backflush the filter twice a day and I still can't get it clear. Should I use two bags of shock?

just got the intex above ground pool which is better liquid or powder shock?

So should I not shock if ph and alkalinity are off?

My pool was installed 4 years ago and we keep it open year around. It has always been Crystal clear and have never been shocked. As a matter of fact we have only added salt and baking soda each year, nothing else. Easy peasy!

I have an in-ground salt water pool, and I know that the iChlor system will produce chlorine on it's own through electrolysis so I should not need to add chlorine to the pool. However, in the winter the water gets too cold for the iChlor to work. Is it recommended to shock the pool regularly with chlorinated shock during the winter months? I watched my pool go from crystal clear to dark green in the matter of a few days as soon as the indicator light on the iChlor that it was no longer producing chlorine.

I need help with getting rid of algae. I have a sand filter.

Is ok to leave floating chlorine tablets when using the shock

Ha, I live in Florida. It downpours one day and the 100 and sunny the next.. so shock rules that you stated would literally be everyday..

I was told by my plasterer (I have a new pool...2 months old now) NOT to use shock the first year as this is bad for new plaster. Have you heard anything like this?

how much shock for a 2000 gallon pool with low ph levels?

What is the difference between regular chlorine and pool shock?! Is a pool shock simply a lot of regular chlorine?

If you are using non chlorine free pool shock do you still need to add chlorine?

Can you please explain it these processes are the same for salt water pools? We use salt in our pool and have a salt generator, so we're never clear on if we should be using as much chlorine or any at all??

My pool guy just came today threw a bunch of shock powder all over the pool and didn’t turn the pump on I didn’t see him mix it in a bucket it’s just sitting on top of my pool water what should l do turn on pump mix it ?? This is a new pool guy not my olde one so I’m used to our old pool guy just coming and doing his think always had a magic touch but never seen shock just sitting on still water l might be wrong tips?

Do you leave it covered or uncovered after shocking, why?

can you shock even if chlorine is high?

Hi mate, I m first time own the home with pool I haven’t any experience how to take care the pool so can you help me I check my pool the chlorine low nothing and ph high up 8 so what best chemistry and what brand I have to put in the pool to balance it, please let me know 🙏

My pool has 7600 gallons of water. Do I still use 1 lb shock?

I shocked my pool last night, but realized it needed more water (about 3 inches). So I filled it. I'm guessing that was a mistake - - throwing off the shock. Now there is algae in the pool. Can you plz confirm? Thx!

Think I already messed it up. I put a bag of shock for 13,500 gallon pool in a 2,500 gallon above ground. Any advice on what I should do. I'm a dummy.

Where buy pool shock in the Philippines?

When you have a sand filter you put it on recirculating or filtering?

Thoses shock treatment are sold in small plastic bags. If I use granular chlorine bucket is it the same product? seems to me but I wanna make sure. I also use chlorinator with pucks for daily dose.

How soon could I shock the pool after using ascorbic acid for stains not to come back?

Orale nice

I can't find chlorine tablets anywhere!! But shock is readily available (and not at a sky high price either). Possible to just add less pool shock granules on a daily basis rather than a floating chlorine tablet holder? Any advice in this regard?

Hi, newbie pool owner here. I have a saltwater pool, should I still shock it weekly?

when shocking your pool should you refrain from other chemical needs of your pool? For instance if you need to shock but Ph is low can you do both at the same time or do you need to wait? If you need to wait how long after shock do you need to wait?

What about us that use a salt water generator?

We have a 10ft above ground pool. I have been using 20g multifunctional chlorine tablets in a floating dispenser in it, and have tested the levels every day, most to all levels are ok, but the cyanuric acid level is high. We have tried draining some water out and replacing it but it’s still high. Someone has suggested using chlorine shock in. Will this help? If so what is the best thing to get (we are in the UK), and how much do we use? It’s 10ft diameter, 2.5ft deep and holds around 1250 gallons of water.

Do I shock a new above ground pool water before swimming?

Should you shock weekly when using a chlorinator like Pool Frog 6100? I do run my pump on low 24/7.

If I shocked my pool two days ago and it rains today do I need to shock my pool again? Solar cover is covering pool during rain. Thanks

Done a backwash, rince, vacuum, shocked it, and all levels are perfect yet my pool is still cloudy

How long after adding Baking Soda should I wait to shock the pool?

I have a pool that I had to fill with well water. I finally got it clear ,Will shocking it turn it green or brown? I have read that it will

…..but if I shock every week it can take 3 days to burn off the chlorine?

Do I turn off the chlorinator after adding shock to the pool?

Lots of us use frog systems etc ...why you always dusting us like we ain't here😂

DO I need to shock a 10ft above ground pool weekly?

Someone told me a photometer also measures total chlorine which test strips cannot do. If your total chlorine is high, then your free chlorine cant work and means your pool is full of dead chlorine. So are they saying the test strips are useless because you can’t test total chlorine? I always thought that as long as test strips says your free chlorine is at 3ppm then that means it’s above total chlorine and everything is ok? OR.. Is it in fact possible for the test strips to read ok at 3ppm free chlorine but total chlorine can still be higher rendering the 3ppm free chlorine useless?

Hopefully you can answer this and point me to the right video. Why do I need chemicals in pool and do I really need them in the pool? My family grows impatient waiting for balancing levels lol

Hi I have a small pool 12x 10 I just filled it with clean water should I shock it I also bought the clear balance. I’m so lost

Do you need to shock your pool if the levels are always nicely balanced? Like I check my chlorine levels weekly and it's totally fine. The salt cell generates chlorine on it's own. Pool is always crystal clear. I also vaccum my pool at least once a week.

What if the temp is 100+ outside everyday do you have to shock everyday?

so shock when you open your pool, shock when you close your pool, shock when its too hot, shcok after a party, and shock every week. so basically live in shock constantly. got it.

First off I am extremely great full for your videos. We bought a house last year and it came with a pool, so after watching your videos I felt fairly comfortable with the idea of pool ownership. Fast forward to today. I shocked my pool two nights ago and added stabilizer because our levels were lower than the recommended level. I expected yesterday to find the pool high in chlorine and a higher level of stabilizer. What I found though was that our chlorine levels, according to the test strips, near zero and stabilizer was almost non existent. I broke out the chemical test kit and checked everything that way. Alkalinity and PH are in normal levels but the chlorine, free chlorine, and stabilizer seemed to be near zero??? I’m so confused. I even checked to make sure that we had chlorine tablets in our Nature2 pod and sure enough we do. Oh and also now the pool is also ever so slightly cloudy. I did add clearifier to help with that but to no avail. Did our chlorine magically evaporate in less than a day? I was curious and did test our test strips by getting them wet and waving them in the chlorine tablet bucket. They almost instantly turned purple on the chlorine square so I know they are “working.” Any helpful suggestions here would be great!! Is it possible our stabilizer is way off the charts and just blowing our test strips and chemical test kit away??

The Clorox company that makes my shock strictly says "do not pre dilute before adding". And they recommend sprinkling it around the pool evenly. is there a reason to not follow their guidance on this?

In Florida it rains everyday. The rain water turns my pool green in just a few days.

When will you put a copy of the "How Often Should You SHOCK Your POOL?" on your Web Site?
