di chlor question

[chem geek]

I'm updating the table to improve formatting and to add columns on the effects on pH and TA after accounting for chlorine usage/consumption:

Type of Chlorine . FC CYA CH . pH . TA . Salt .. Typical Dosage per 10,000 gallons per FC
Trichlor ................ 10 . 6 ... 0 ... -- .. -7 ..... 8 .... 14.6 oz. (109 grams)

Dichlor ................. 10 . 9 ... 0 ... - . -3.5 .... 8 .... 24.1 oz. (181 grams)
.................................................. ..................... for Dichlor Dihydrate

Calcium ............... 10 . 0 .. 7-8 .. 0 ... 0 . 10-12 . 20.7 oz. (155 grams)
Hypochlorite .................................................. .. for Cal-Hypo 65%

Sodium ................ 10 . 0 ... 0 ... 0 ... 0 .... 17 ... 102 fluid oz. (800 ml)
Hypochlorite .................................................. .. for 12.5% (trade) chlorinating liquid

Lithium ................ 10 . 0 ... 0 ... 0 ... 0 .... 17 ... 38.3 oz. (286 grams)
Hypochlorite

Chlorine Gas ......... 10 . 0 ... 0 .. --- . -14 ... 8 .... 13.4 oz. (100 grams)

Saltwater Chlorine . 10 . 0 ... 0 ... 0 ... 0 ..... 0 .... N/A
Generator

I show the hypochlorite sources of chlorine as being pH neutral, but they do have a small amount of excess lye (or equivalent) in them so slightly raise the pH, but the main source of pH rise in pools using these chlorine sources is outgassing of carbon dioxide.

all typed and entered in my Pool Care binder. Thanks much

Chem_Geek's very helpful table, in a little different form:

Is there a way this can be made available out in the open for everyone....like before you ask...CHECK THIS OUT!! This is super great! looks like bleach and cal hypo are the non invasive way to go for just raising chlorine other than salt

[PoolDoc]

Yeah, I've saved it for use elsewhere. There are 2 other calcs I've asked Chem_Geek about, though.

thank you
