Which chlorine & why?

[Huckleberry]

I use granular chlorine since it is dust free and dissolves pretty fast.It can also be applied as shock for regular chlorination.

At home I use an Aqua Rite Chlorine Generator. This equipment does all the work for me. It was packaged with a chlorine solution already. With this I no longer need to change the chlorine of my pool frequently. For me, this pool equipment is wonderful!

I have a 30,000 Gallon Hayward saltwater pool with an Aqua Rite Chlorine Generator. I live in the Philippines and as you can well imagine, It is hot all year and the sun eats chlorine like Pac-Man. Even with my Generator set to Super Chlorinate (Shock setting) it is not enough to keep up with the chlorine demand. I keep 4 or 5 Gallons of Chlorine bleach on hand and add a gallon when the level drops. The main reason I use the regular bleach is the availability of pool supplies is very limited here in a small city.

What you say makes the most sense, other products put additional chemicals (CYA) in your water making your chlorine ineffective and building up your calcium
For every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm.
For every 10 ppm FC added by Dichlor, it also increases CYA by 9 ppm.
For every 10 ppm FC added by Cal-Hypo, it also increases Calcium Hardness (CH) by at least 7 ppm

When your SWCG packs up make sure you get one that is at least double (or larger) than the rated output requirement for your pool and isn't running 24/7 at 100%

Do you have any CYA stabiliser in the water? Unless you buy stabilised salt you'll need to add it. Without it your chlorine will burn off in a couple of hours and your cell will not last

I'm glad you posted this topic, as I've been wondering which one to use also.

Without knowing what the pros and cons are you'll be in danger of posting stupid nonsense like some of the previous posters.
We have the information and we don't charge for it so ask and also have water test results to hand and not from dip strips.

Liquid chlorine is generally less costly than granular shock and comes in refillable containers, where granular shock does not. Liquid chlorine does not need to dissolve in your water as it is already in liquid form. In addition, liquid chlorine is non-scaling and leaves no residue. So I prefer Liquid chlorine

And you are not adding unnecessay CYA

[tcjack]

Trichlor primary, bleach and liquid chlorine for shock.

Look at Chlorine / CYA Chart
Excessive CYA renders your chlorine ineffective and you have to use more to get the same sanitation
For every 10 ppm Free Chlorine (FC) added by Trichlor, it also increases Cyanuric Acid (CYA) by 6 ppm.
For every 10 ppm FC added by Dichlor, it also increases CYA by 9 ppm.
For every 10 ppm FC added by Cal-Hypo, it also increases Calcium Hardness (CH) by at least 7 ppm
To reduce your CYA you have to do a partial drain and refill
Continuous use of Trichlor/Dichlor will raise your CYA which means you have to raise your chlorine level as well

[Marilyh]

I usally use Trichlor Tablets. Because Chlorine with stabilizer (CYA) is crucial for consistent treatment as UV radiation can rapidly degrade chlorine; however, CYA accumulates over time and doesn't naturally decrease. To reduce CYA, partially draining the pool, ideally from the bottom where CYA concentration is higher, is the most effective method.

[Jentiferr]

I usually use Trichlor Tablets for my pool. It is convenient and cheap.

[Teapot1]

Well cheap until you have to partially drain and refil to lower CYA level. If you have treated the water further to lower Alkalinity etc then you go through more process's. Some areas have water shortages which forbids emptying and refilling.
All this can be avoided by switching to liquid bleach.

[Denniswiseman]

Clorinating liquid and plain bleach are the same thing Sodium Hypochlorite
