How Much CHLORINE Should You Add to a POOL?

How much chlorine does your pool need? Usually, it only takes a few tablets or a cup of granules to keep your water sanitized. But it all depends on the size of your pool and what type of chlorine you buy. So here’s a quick guide on figuring out exactly how much chlorine you need to add to your pool.

Have a bestway 18ft by 4 ft tall pool that hold approx 6092 gallons of water. Only 1 inch tablets I could find at Walmart were the HTH sanitizer with added clarifier (Trichloro-s-triazinetrione). Do you recommend using only one or two of these 1 inch tablets as maintenance in my pool?

Love your videos, they’ve helped me maintain my pool great, thanks so much! ❤️

You can get chlorine granules without CYA then add stabilizer separately when and if you need it. Not sure why this wasn’t mentioned

Hi there, how much granules of chlorine in my 15' round and 3' high pool need? And how often would I put chlorine? It's the pools that you put air in top and fill with water. I'm also wondering, would I need to put shock in? I just added fresh water to it a few weeks ago. Thanks 😊

Thanks

I have to use liquid chlorine because my CYA levels are outrageously high.

I've had good luck with 3" tabs in the past (30, 000 gallons, auto chlorine feeder), but my cya levels were of the charts last year, even with replace about 10, 000 gallons. Advice?

What do I do if my pool is only 1080 gallons of water

bro there is beeping sound in ur video

[mattdudamusic]

I’m sure you have a valid message to convey but it’s difficult to concentrate on your words with all the sound effects (whooshes, music, etc.) accompanying the visual arrows on screen. Perhaps mixing the music and sound effects much lower than your voice would be more effective

[Petreski]

It says on the label bro, what this? 90% chlorine for me 3 grams/m3
Also it’s 2 to 4 ppm

In your email you said "I just published a video that breaks down exactly how much chlorine you need based on: 

Your pool size

The type of chlorine you're using (tablets, granules, salt or liquid)

Your current chlorine levels 

You never included any information about salt in this video.
