Chlorine granulade this year and testing kit.

[yesjenks]

Hello TroubleFreePool,

Hope you and all your families are doing well!!

I live in NNJ and like much of the nation, I try to not go out unless I absolutely have to. That said I'm looking to open my pool and in the past I've mostly used liquid chlorine which is going to be a problem this year. I'm looking into alternatives and came across this "
Doheny's Di-Chlor/Granular Chlorine". Will this shred my liner? Any other suggestions?

Also, I bought a testing kit on here a few years ago. Can someone steer me in the right direction of ordering another/refills?

Thank you!

TFTestkits.net for the refills.

The product is dichlor. It will add CYA and chlorine. In about equal amounts. Be aware it will raise your CYA rapidly.

Be sure to check Walmart, Home Depot, Ocean State Job Lots, etc for Liquid Chlorine.

Thank you!

Is there a form of granular chlorine that won't raise my CYA? Unless I'm mistaken no one will ship liquid chlorine. Right?

 

[mknauss]

I do not think anyone will ship liquid chlorine.

Calcium Hypochlorite will add calcium. What are your test results on CH in your pool water?

 

[yesjenks]

I haven't testing since the end of last year and I'm looking for, but can't find the spreadsheet I used to track last year's results.

I definitely don't want to raise my CYA as I fought that battle 2 years ago. Need to research the effect of increasing Calcium.

Thank you!!

This seems like the better of 2 evils.

 

[mknauss]

Could be. Be careful how you add it as any Cal Hypo granules that sit on your liner will bleach it out.

 

[yesjenks]

Welp, don't want to do that!

Need liquid chlorine!

Check Ocean State Job Lot. Shows availability in your area.
