Great video, agree with everything! Liquid chlorine only temporarily increases the pH. Afther a few hours the pH should be equal to before you started the addition. HOCl turns into HCl (which lowers the pH) and NaCl (salt) if you have a salt water pool. I would advise anyone with a swg who temporarily shocks the pool (to lower combined chlorine e.g.) to turn off the swg for a couple of hours as inside the swg combined with higher pH will create a (higher) LSI violation and may create calcium. Thanks for this video with your great advice.
I did liquid chlorine for a while thinking it was better because it would be effective immediately and not have to be disolved like granules or tablets. It worked for a time but then I would still get green water even with very high chlorine levels. Dichlor granules seemed to work better for me. I do have a question though - some sources say it is not advised to use different chlorines in the same pool, such as using dichlor and trichlor at the same time. What are your thoughts on that?
Yeah, that's the downside to liquid chlorine: it's less potent. Great for smaller pools, but requires so much more in bigger pools. Plus CYA. I wouldn't risk mixing chlorine. You should never mix two types of chlorine together outside of the pool. Which also means that you shouldn't mix them in a "container" like a chlorinator or floater.
@@SwimUniversity I understand not mixing different chlorines before adding them to the pool, I was asking about using different chlorines in the same pool. I would assume that is OK?
Are you saying “maintenance dose” as one treatment? For example my 10k gal pool adding 1 gallon of 12% raises my chlorine 12ppm. Should I be dosing it all at once because I usually daily dose around 12-24 oz depending on my daily loss. Thanks for sharing these videos with all of us!
What size pool do you have? We have a 18x42 BestWay. I’m thinking about switching to liquid because I’m having an awful time balancing and seem to always have more total chlorine than free. I definitely think the tablets are better for larger pools
The CYA reducers have mixed results. You can try it if you absolutely can't drain and refill your pool. But that's the only guaranteed way to bring down CYA.
I just went through this. bought a 1/2 hp utility pump off amazon and hooked up a garden hose. ran the hose to my sewer drain out. just do partial drain and refill. I let it drop 7 or 8 inches then refilled. then repeated that process three times. My CYA and total hardness dropped to good levels and I was able to slowly balance it back correctly. hope that helps.
I have a hot tub and have been using stabilized chlorine granuals. In your opinion is liquid chlorine and cya better than granulated chlorine. Should I consider changing?
My hot tub is cover at all times unless its being used. If thats the case, should i continue with the chlorine granules or change to liquid chlorine? Is there a benifit one way or the other? Thanks.@@SwimUniversity
Hi Matt, I have been using trichlor tablets for a long time and my CYA is really high at about 200 ppm. I replaced a lot of the water and still have really high CYA. I know if its high the CYA, the chlorine is inefective. The more I use the tablets the more the CYA keeps building up. I want to go to strictly liquid. Sooo will the CYA disapate? Al;so I must have chloromines because Im adding 10oz of liquid everyday and which brings up the free chlorine but by evening its gone. HELP!!!!! It cost mucho$$$$$$ , thanks in advance
Definitely stop using tablets and the CYA should stop rising. Unfortunately, you'll need to drain and refill with fresh water to bring the CYA down. Once it comes down, the chlorine should be able to work better. You can tell if you have chloramines if there's a big difference between your FREE CHLORINE reading and TOTAL CHLORINE reading.
@SwimUniversity My Liquid trichlor chlorine gallon bottles say they're 90% chlorine, not 10%; in such case, how much should I drop weekly? shock? I have 22,000 gal pool. I also have a chlorinator where I can drop chlorine tabs; how many chlorine tabs should be in there at a time? fill up the whole chlorinator and change the setting?
You need 4-5 tablets (3 inch) to sanitize 22,000 gallons of water (1 tablet for every 5,000 gallons). What brand is your liquid chlorine? It should definitely not be 90%.
Dear, we have an dancing fountain, of around 1.6 million gallons. And our ss equipment in it is now covered with stubborn sticky algae, and also dark greezy spots on floor. These problems came after an incident of 400 liters kerosene was leaked inside ... Is there any thing to eliminate its effect ??
Why does my pool have a chorine block? I’ve taken it to 2 different places for testing the waterline alkalinity and ph were adjusted. Water is clear . I can see clearly in the deep end. My pool is close to 30,000 gallons.
The bottle says to add 13oz for 10,000 to increase 1ppm. I have a 7600 gallon pool so I added 30 oz and saw zero difference. Guess I’ll just add 3/4 of the gallon and test again.
I shocked my salt pool due to Algae with tablets and had calcium issues for months. Bought liquid for the future. Never again. No pool guy is using solid chlorine, they all use liquid!

Thanks for the science behind that! And good advice on turning off the salt water generator for a bit
Thank you for your helpful videos! 💦 👍👍👌
Glad you like them!

Are you doing this daily without CYA?
@@SwimUniversity cya 45 using pucks in chlorinator set very low.
Been using liquid chlorine for years ...never had an issue 😊
That's great! What size is your pool?
@@SwimUniversity 12 x 18..2 cups of chlorine a day all summer snd that's it ! 😎
You add 2 cups every day? Our pool is 14 feet.
I get it. He said if you don't add stabilizer, do this daily. Got it!
@@nathanharper7562I bring up my stabilizer to the correct level at the start of the season and never touch it again
i have an oxygen-systems(ozone) pool. do you have any videos or insights on that?
We can make a video about those systems in the future!
I use liquid chlorine. Never have to worry about shocking my pool or turning green like I hear alot of people complain about.
People complain because they dont live where u live.

Is your hot tub uncovered during the day? You shouldn't need stabilized chlorine if it's not exposed to sunlight.

What's your chlorine at? Check out this article we have for help: www.swimuniversity.com/chlorine-lock/ TLDR: Shocking can help.
Too much CYA?

No true many pool guys use shock especially in areas where the weather is really hot
Now talk about the downfall of CYA
For the life of me I can’t get the pool clear up its still cloudy
Use a clarifier
Check filter. 🫡
What have you tried so far? And how are your chemistry levels?
A good corded pool vacuum with extra fine filter will also help with proper chemicals
When is the last time you did any maintenance on your pool pump?
How’s your circulation?
Liquid is not great for super hot climates.....Texas for instance. Cali designed vids
