Which type of chlorine do you use in your pool?

@loucatozzi7656 5 лет назад

I have a salt water system for chlorine generation. My question is about stabilized vs unstabilized SHOCK. I was told by another pool person that I should buy stabilized SHOCK but now my CA levels are slowly rising as the season progresses. I've had to drain out most of my water once already after using the shock to fight off an algae bloom when I opened the pool for the summer. Should I switch to unstabilized shock? I do have a supply of CA left over from last year.

@SwimUniversity 5 лет назад

I get buying stabilized shock for a salt system, but you'll have better control if you use unstabilized shock and add chlorine stabilizer separately. You don't want the CYA levels going too high.

@Griffin8s 5 лет назад

My question is using a salt system I make my own chlorine why spend the $25 for 4 lbs. of stabilizer? A bag of salt is $9. I do take my water to the pool store to be tested and the only thing they tell me I need is stabilizer. Should I buy it?

@loucatozzi7656 5 лет назад

@@Griffin8s My salt system is from Intex, the same maker as my pool and other equipment. It is very inexpensive (compared to other salt systems, at least) and it does not produce a whole lot of chlorine each day. As the summer gets hot in Texas I find that I cannot maintain the chlorine at 2-3 PPM as needed unless there is at least 30-40 PPM of stabilizer present. Without stabilizer the salt system just cannot make chlorine fast enough to keep up with the sun burning it off.

@SwimUniversity 5 лет назад

It's just for those times when you're not running the generator that the chlorine will stay in the water while the sun's out.

@jANETbERRY-go5er 19 дней назад

brilliant! we can find this info in gits and pieces all over the web..... BUT you do a super great job of explaing in a way that it all ties together nicely and youre slightly more entertaining thjan most of these "POOL HOW TOs"! Thank you.

@GuinnessPhish 3 года назад

"commonly shock is unstabilized chlorine". If the shock lists "calcium hypochlorite", then it doesn't contain any CYA (cyanuric acid/stabilizer). If the shock lists di-chlor... it does contain CYA/stabilizer.

Your videos have really helped me. I created a Playlist called "pool school" in my you tube account just for my quick go to vids when conducting maintenance on my pool. I feel like it's a calming /relaxing job now to perform the weekly maintenance, vs like before feeling like it's a foreign language with all of the pool jargon. I believe I will save a lot of money by learning how to take care of my pool by watching your vids. and downloading the quick guide. I will be purchasing the handbook soon! Thanks!

It is such a pleasure to find a site that takes their time to thoroughly explain all aspects in such a manner, that the regular home pool owners can actually understand what information is being presented. Please continue with presenting more information that answers the questions of regular and commercial pool owners.

@rocko107me8 Год назад

This was super useful. I changed my Salt Cell last year to my AutoPilot system(original last 10 years), and this year in particular it just doesn't maintain a clean water even though the level looks correct. Tested my cyanuric acid level after watching this...its its practically non existent. Combine that with a hot and dry summer with hardly any rain and that is probably the issue. Going to add stabilizer for the first time in 12 years :D

i tried adding stabilizer to my pool, its the first brand i tried but it was little hard pieces so i tried to crush them in water and add it once it desolved but i could not get it to disolve so i just added it into the pool thinking maybe it takes a while..well nah it just settled to the bottom so i had to vacuum it all up..did i do something wrong?

I'm in south Florida... where it's about to get HOT. I use liquid chlorine /shock from PAP. I also was told to use 2 3" tablets to float (they have stabilizer 4 in 1) a week. Does this make sense or is it excessive? (10,000 gal pool non salt)

@andrewpaschalis4055 Год назад

I balance my pool with a Taylor CK - 2005 test kit about 2 months ago. Recently the past week my free chlorine has been registering over 10 ppm. I turned off the automatic chlorinator for the past week and the free chlorine does not seem to have lowered at all when testing daily. I use stabilized chlorine pucks and wondering whether that may be causing an issue. Any help you can provide would be appreciated.

@laurakingdom4 2 года назад

Still pool learning! So this is great. I hadn’t realised there were two types of chlorine. So hadn’t been shocking my pool! 🙈 I soon learnt after my PH became to high. We had an algae bloom. We have now shocked the pool using unstabalised Chlorine. I may have over done it! My dip stick is the darkest colour for chlorine….. and it’s been cloudy all week 🙈😂 this pool maintenance stuff is hard work!!!

@webneko9842 10 месяцев назад

So, before I found your video and just learning my pool, I used only stabilized chlorine granules for weekly maintenance and pucks in a floater. I found that doing this, I raised my CyA way too high. I didn't understand why, especially since I regularly flush my sand filter, so I am draining some water and replacing and my CyA was still high and not dropping. I then watched this and realized I need to be using unstabilized. I buy liquid version and it is easy. And later, use stabilized when the CyA is back to normal to shock and to maintain that CyA level is what I am learning.

Thank you for your videos! I am new a new outdoor owner! For my chlorinator, I have Nature2 Vision Pro Vessel that uses a chlorinator canister. I have the V-Pack Chlorinating Canister that has the tabs inside. The canister label states that it limits chlorine exposure. Every time I test the pool water, my chlorine level is low. Do you know if this could be because of the cartridge? The water looks clear, but I'm just wondering if it is safe to swim even though the reading is low. :)

@charlies.5777 5 лет назад

I typically use the ABC method ,whereby : A= Maintaining the chlorine level with Trichlor pucks (stabilized) in a floater. B= Shocking weekly with liquid ( unstabilized) shock. C= Adding a weekly maintenance dose of POLY algaecide/clarifier. If I want to lower the pH and add a bit of stabilizer @ the same time, I'll add Trichlor or Dichlor granular shock.

@johnroberts7018 Год назад

I love Swim University and these videos. Only thing I would say is....wouldn't you want your FC just a little higher if your CYA level is 50 or so? like 4ppm instead of 3ppm? If I'm wrong feel free to say so. Thx again for the great videos!

@x65535x 3 года назад

Your video makes it sound like the straight NaClO doesn't benefit from the separately added Cyanuric Acid. I have found with my heated water (95F) and SoCal UV exposure that I can burn 1 gallon worth of dilute NaClO in 2-3 days even with 40ppm Cyanuric Acid. I've run 2 stabilized tablets at a time and found no improvement in levels. The liquid seems to be the only thing that can keep my free Cl levels in the proper range. I do have rather hard water, and I also usually add about ½ gallon of Muriatic a week to keep the pH 7.5. Should I be using stabilized Cl or is the manually added Cyanuric granules to hold 40-60ppm sufficient with the liquid Cl to get the most bang for the buck out of sanitizer?

@angusmcpherson 10 месяцев назад

Using pucks for a year my CYA levels got up to 150 ppm which knocked out the chlorine's ability to sanitize. Next thing i knew i got an algae bloom that no amount of chlorine could stop. I had to raise the Ph with bicarb of soda and address the algae with algaecide and clarifier. Ran the pump 24 hrs and my pool is clear. Algae settled to the bottom which i will vacuum to waste.

@jenniferoxendine9648 3 года назад

Thank you!!!

@lsmuz66 3 года назад

Great review, but which Chlorine tablet do you use if you CYA is 150 ppm, and your hardness is over 800 ppm. This is my case. I know the answer is to drain the pool, but we are under server water restrictions. I do plan to drain the pool, but after we are off water restrictions. I am now using Sodium Hypochlorite liquid for chlorinating my pool. It does not leave extra CYA in the pool, and does not add to my Calcium hardness problem. It is not that expensive.

@hunglong6587 2 года назад

My fool same if your. I am wait this winter the water restriction off to drain the pool during I have to use more sodium hypochlorite liquid for keep the pool has chlorinated. But the sun burn it very quicker, My pool PH high 8.2 I try to lower ph by pour muriatic acid in but not go anywhere ph still stay the same and my pool start has some yellow algae grow around the wall and step what do you do fix that.

@DrinksandDIYwithSuzy 3 месяца назад

I have a saltwater pool with salt cell to generate chlorine. I've noticed my total chlorine is always high (like 10ppm) while active chlorine is always low (0.5-1.0 ppm). I've added dichlor shock, and I see total chlorine keeps at the 10 ppm level, instead of balancing it. I've tried to increase my chlorine production in my salt cell, and still total chlorine is high, but active is low. Do you have any advice? Thanks!

@whoknows9063 3 года назад

My first time purchasing a 10 by 30 pool what should you recommend for cleaning products?

@brendaannan5154 2 года назад

I recommend Leslie Pools “NoPhos” down the skimmer to clear up algae. Then I recommend “Perfect Weekly” sold by Leslie Pools. You can purchase online and have it shipped but we live near a Leslie Pool Store. First test for pH and alkalinity. Use an algaecide once a week. Shock once a week. Don’t use too much shock because you will have to wait until the chlorine level is between 1-4 ppm before you can swim. With heavy rain the algae is more apt to grow so you may have to add an additional dose. If you use the Perfect Weekly from Leslie Pools you will have a beautiful, clean pool and less work. On a daily basis you can use chlorine tablets. When you begin the season each year and your pool is green, I highly recommend NoPhos. It kills the phosphates which feed algae. Without phosphates in your pool the algae disappears.

@PanTheManInNeverland 5 лет назад

Great breakdown of the different Chlorine forms and their uses! Question, is a floater (with adjustable vents) a good way chlorinate? I didn't know you could put it in the skimmer basket, is this a good route?

@SwimUniversity 5 лет назад

It's an OK way, but I would recommend a chlorinator first, then just using your skimmer basket. Though some folks would say that's a bad idea, I've been doing it for years with no issues. It distributes chlorine more evenly than the floater. I just avoid floaters altogether.

@PanTheManInNeverland 5 лет назад

@@SwimUniversity I normally put about 3 pucks in for my floater. Should I drop that down to 1-2 and refill more regularly if I were to use the skimmer basket?

@SwimUniversity 5 лет назад

Possibly. Hard to tell. Try it and keep testing it to make sure it's working. The pucks will dissolve faster in the skimmer for sure.

@ovslugger6588 4 года назад

If you have a heater, I would avoid putting in skimmer because that could cause big problems to your exchanger and other internals. Best bet would be an in line tablet feeder. But without a heater, skimmer works great like he said.

@macknumber9 2 года назад

If i add the pucks that have stabilizer in them wouldn't the stabilizer levels keep rising each time i added new pucks seeing how the stabilizer doesn't go down unless the water evaporates (you drain the pool)... Wouldn't stabilizer just keep rising? I'm really confused by this....if one puck provides say 5ppm stabilzer would i not have enough stabilizer until i added around 6 pucks? Then i would keep adding 5ppm every time? I know this isn't the case but i like to understand how this works

@kanwalsmalik 5 лет назад

@50kal44 3 года назад

Nah commercial pools are really high all the time it’s fine

@brendaannan5154 2 года назад

Try using “NoPhos”. It lowers phosphate levels in your pool. Algae feeds off of phosphates. Then when your algae clears up you can add “Perfect Weekly” by Leslie Pools. That way you won’t have to use so much chlorine. Your pool will be a clear blue. Of course, balance the pH and alkalinity as much as you can first.

@markusahn 3 года назад

What about Ozone Pool System

@ruthlessluder 3 года назад

Since you said the only way to lower CYA is to dilute your water, does that mean once your CYA gets to 50 ppm you can stop using tablets forever and just use unstabilized chlorine? I know pool water evaporates but other than that, does CYA work indefinitely as a stabilizer?

@carlwillms3049 2 года назад

It appears I may be having a Chlorind Demand issue for the first time in 10 years. I tried increasing the chlorine with extra tablets in the return basket and some floaters along with the inline dispenser. Despite all the tabs disproving the chlorine level is still less than 0.5 but I am worried that my Cyanuric acid is getting too high as it approaching 80ppm where it is normally around 50ppm. Normally 2 bags of shock in my 25,000 pool in the evening takes care of the issue and leaves the pool chlorine at around 4ppm the next morning, but now the chlorine is still staying below 0.4ppm. PH and alkalinity are fine. I am going to try some liquid chlorine, significantly less expensive than bags of shock, but I am not sure how much to add. I noted a recommendation of "You'll need about 52-104 oz of liquid chlorine per 10,000 gallons of water. This amount should get the chlorine level to between 5 and 10 ppm." So I am thinking approx 200oz or about 1.5 gallons. Any suggestions? If the liquid chlorine works, I will post an update.

@carlwillms3049 2 года назад

I added 2 gallons of liquid chlorine and in the morning before the sunlight hit the pool, the chlorine level had dropped even lower than it was before I added the liquid chlorine.

@thespencerowen Месяц назад

@vrglcom 3 года назад

Can I please ask, you say you can use un-stabilised chlorine to shock pool, and then normal stabilised chlorine to keep the pool sanitised on a daily basis.. I’ve read some websites warning that if you use both un-stabilised and stabilised chlorine in the pool it can explode!? Is this true??

@nationalstreak 3 года назад

Not true at all. Although, I definitely would not use stabilized chlorine on a daily basis, only as needed. If the stabilizer level is too high (above 50ppm), you should only be using unstabilized chlorine.

@chaysecsongedi2480 11 месяцев назад

You should be shooting for a 30-50 ppm on cya, anything over 50 will cause lock out on stabilized chlorine and at a 60 you need a 6 to have any active chlorine. Currently they are working on changing suggested cya levels to 8-32 ppm. Also keep in mind adding cya lowers ph as it has a ph from 3.3 to 4.0, which as it sets in will counter act a shocking treatment. If cya gets to high you out risk to teeth hair bones as well as lowering ability to remove pathogens.

A day, a week, before changing to unstabalized tabs? Please help and let us know if there is anything else to be aware of to transition.

My pool over the winter has insane algae. I have shocked it so much over the last week it should be glowing in the dark by now. But I still have algae stuck to the walls and staining. And the stains are more brownish red. Probably coming from the leaves from our trees falling in the pool. What are your suggestions for the algae stuck on the walls and the staining

@bobwachter8811 2 года назад

Get a phosphate test kit and a good phosphate treatment. At 150, algae can't grow. Not sure about stains. Good luck

@megalou6567 Год назад

You may have high cya now . If you do the chlorine won’t be effective

@lrakwons9799 Год назад

If the water is clear I’d say to balance your chems, get your alk then ph where they should be. If the linear is literally stained green where you can’t get it up from all other methods there’s stuff called stain remover. Have done it for 3 different customers now and have been impressed

Question - When I add unstabilized chlorine in the evening and it works its magic overnight, how quickly does it burn off the next day when the sun starts to hit the water?

@SwimUniversity 5 лет назад

Roughly 1ppm every hour in the sun.

@brendaannan5154 2 года назад

This is just my opinion, but I think it will burn off more quickly if you live in Arizona and Florida. If you live in New England it could take longer because the sun is less intense the further away you go from the equator. I’m not an expert.

@@TimLewallen you must have a much longer pool season than us New Englanders! It was even shorter this year due to the rain, but we can always use rain, so I will accept this as a shorter season than most.

What I realized is chlorine/pool chemistry is just crazy. Trichlor is mostly tablets but it does exist as granules and vice versa for dichlor. Calcium hypochlorite increase CH. dichlor increases cya. There’s stabilized and unstabilized chlorine in forms of granules/ shock and I bet even in forms of tablets. And then there’s completely different forms of “chlorinating” such as bromine, salt, and probably a whole lot more I don’t even know about. I give up, it’s just crazy.

I have a LOT of cyanuric acid in my pool. Well over 100 ppm. How could/did that happen? Thank you for your videos!

@SwimUniversity 5 лет назад

From adding chlorine stabilizer or stabilized chlorine tablets. Just drain the pool a little bit and add fresh water to bring it down.

@mikehatley4325 4 года назад

Ok when I add unstabilzed chlorine, it turns my pool green. I’m guessing I have a metal problem. I’ve added sequestering agents to get it blue again. But this last time I shocked with liquid it turned green and stayed green, even after the sequestering agent.

@brendaannan5154 2 года назад

If your pool turns green that is probably an algae problem. Algae feeds off phosphates. Your phosphate level could be high. You can buy NoPhos liquid in a bottle from Leslie Pools. If you have a 10,000 gallon pool you add two capfuls of NoPhos on one day down the skimmer. The next day you add two more capfuls of NoPhos down the skimmer. This will lower your phosphate level. In turn, it will take care of your algae problem. You may have to repeat this procedure the following week. There is a wonderful product sold by Leslie Pools called “Perfect Weekly”. You can add some of this once a week down the skimmer. Your pool water will look really great! Be sure to add your algaecide once a week. Shock the pool once a week. I believe you can order products online and have them shipped from Leslie’s Pools. I had so much success with the NoPhos and the “Perfect Weekly”. Amazing results and it makes pool care much easier. You can read the great reviews on the Leslie Pools website for “Perfect Weekly”. Doing these things turned my very green pool to a clear blue. Of course I did try to adjust the pH and alkalinity first.

@justinbailey9950 2 года назад

So how do you keep you cya from getting too high and also keeping your calcium from getting too high

@simmonsco Год назад

If both your cya and calcium are both at their maximum level or higher, use liquid pool chlorine as it doesn't have calcium and it doesn't have cya. Walmart, Lowes, and Home Depot has it by the gallon and it is 10% Sodium Hypochlorite.

@theotherguyspoolservice8387 4 года назад

Does'nt putting tabs directly in the skimmer can mess up your equipment

@Paggy6668 3 года назад

Yes, it can. When the pump turns off, those pucks are sitting in the skimmer and and the water around them becomes very concentrated with chlorine. Then your pump turns on in the morning, and guess what, that concentrated chlorine goes to your equipment and can deteriorate o-rings and rubber gaskets prematurely.

@giobucks6498 3 года назад

Only way to lower cya is to dilute water? What about a cya reducer?

@ArKka2311 4 года назад

Please tell me why every time I shock my pool my water turns yellowish. I was told it´s caused by minerals--primarily iron. How can I prevent this from happening? I would really appreciate it.

@akronorka 3 года назад

You need to use a metal and stain product in a double or triple dose, treat staining with vitamin c, and use a maintenance dose of scale and iron remover if topping off with well. Basically when you shock, you’re super oxidizing copper or iron and that’s why it’s turning on you. Need to remove the metals before somehow. If your water is that bad you’re gona need in line hose filters for filling.

@Rithius3485 5 лет назад

Thanks for this video!! I was just dealing with this. I got stabilizer from my pool store in the form of a bag of granules and it said to just put in pool, and they just sit on the bottom for a long time.. I tried to pre-dissolve in a bucket, no better.. what do I do? Also how do you test for the 50ppm of stabilizer?

@SwimUniversity 5 лет назад

Keep brushing it up until it dissolves. And you can buy a test kit or strips that’ll test for CYA. Or take it to your local pool store to get it checked.

@ovslugger6588 4 года назад

I have always added stabilizer directly into skimmer but slowly and with the basket in. I have also seen techs get rushed and end up causing clogs by pouring into skimmer without the basket in.

@jakegraenicher3633 4 года назад

Stabilizer should always be added slowly to the filter (via skimmer usually) Allow 48hrs to dissolve. Best to backwash before adding. If added directly to the pool by mistake I recommend brushing into to the drain or manually vacuuming to the filter. Also consider that adding to much stabilizer at one time may clog your pump basket especially if added too quickly.

@dasottonator1363 11 месяцев назад

I have never added pure CYA to my pool . Only the micro dosing from the floaters . But some how i have excessive stabilizer when testing . Cant afford to dump large amounts of water due to being in a water scarce region . Is it possible the the micro dosing from the floaters builds up to high levels over time ?

@benparsons5197 11 месяцев назад

My understanding is CYA does not decrease on its own. I’m currently draining my pool bc of this.

@larrysmith2612 11 месяцев назад

I was having to change my pool water every year because it was becoming overstabilized. What I did was drain and refill my pool then use tablets until the stabilizer reached the proper level (50 ppm) and then switched to liquid chlorine that is unstabilized. It's kind of a pain to hustle gallon jugs of chlorine around but my pool water is 3 years old now and it looks and tests great. Your pool water should last 3 to 5 years using this method.
