Kind Of Swimming Pool Chlorine To Use

by Mike
(South Carolina)

I have a question about swimming pool chlorine.


I know there's a couple different ones out there but which one is the best to use, the liquid or granules?

Which one does a better job?




Thanks for your questions Mike

I actually prefer Calcium Hypochlorite (granular pool chlorine) over liquid chlorine for a few reasons:

1. It's safer
2. Lighter
3. Easier to store
4. Easier to apply

Swimming Pool Calcium Hypochlorite

Swimming Pool Sodium Hypochlorite

If you live in a part of the country that has high hardness fill water you might be better off using liquid chlorine as the granular pool chlorine does contain calcium which may increase your pool water hardness.

As to which one is better; I think both kinds of swimming pool chlorine will do a great job sanitizing your pool.

For ease and convenience I always go for Calcium Hypochlorite.

Hope this helps

Grocery Store Bleach/Clorox Instead Of Pool Chlorine?

by Judy
(Kansas)

Can I just add bleach or Clorox to my pool instead of pool chlorine and buying expensive pool chemicals?

I've heard that it's the same stuff but other people have told me not to do it because it's dangerous.

Any help?




Thanks for the question Judy

There is a ton of misinformation in pool land about this very topic.

Clorox, or regular grocery store bleach, is roughly 6% sodium hypochlorite and the rest is water with a tiny bit of salt.

Liquid pool chlorine is normally 10-12% sodium hypochlorite and the rest is water with a tiny bit of salt.

Swimming Pool Sodium Hypochlorite

Swimming Pool Calcium Hypochlorite

THEY ARE IDENTICAL except for strength.

Clorox and bleach have been used in thousands of pools daily. It's not necessarily cheaper, but frequently more convenient.

More importantly, places where you might have high hardness fill water, sodium hypochlorite is, by far, the BEST thing you can sanitize a pool with.

Simply because nothing gets added to your swimming pool except the little bit of salt.

All other forms of chlorine add other things to your pool.

For places with low hardness or very soft water, I've always preferred calcium hypochlorite because it's a bit safer, lighter, and easier to store and apply.

Hope this helps

Difference of Calcium Hypochlorite & Sodium Dichlorite Triazinertrione?

by Yvonne
(Jeanerette, La.)

What is calcium hypochlorite? What is sodium dichlorite triazinertrione? Can both be used in an inground pool?




Thanks for your questions Yvonne

Calcium hypochlorite (cal hypo) is the granular form of chlorine and has about 65 - 68% active chlorine. The rest is calcium which is used as a binder and it usually comes in a bucket.

Calcium Hypochlorite

I prefer cal hypo. because it's a bit safer, lighter, and easier to store than regular liquid chlorine. A drawback is that places that may have higher calcium or hard fill water shouldn't use cal hypo. because it introduces more calcium into the pool.

For sodium dichlorite triazinertrione, I think you might be referring to sodium dichloroisocyanurate.

Chlorine Tablets

This is a granular, stabilized, and fast dissolving form of pool chlorine and is often used as a pool shock. While Dichlor does add pool chlorine it will also increase your cyanuric acid (CYA) level while lowering your pool water pH level. Take care in using Dichlor as your CYA can get out of hand very quickly.

Adjust Your Swimming Pool Chlorine

Both are safe to use in inground and above ground swimming pools. Remember to read the safety labels and take the proper precautions when dealing with any pool chemicals.

The above links will show how much chlorine and CYA to add to your pool to bring them to their proper levels. Hope this answers your questions and good luck with your pool

All the best
