Bleach vs Cal Hypo.

Technically, both bleach and Cal-Hypo raise the TA when they raise the pH, but they do so in a way that the consumption of chlorine returns the pH and TA back to where it started.

However, bleach does not increase CH whereas Cal-Hypo does. Cal-Hypo increases CH by 0.7 ppm for every 1 ppm in FC that it provides.

Now I got the whole formula now

baking Soda : increase TA + PH
Muriatic Acid: decrease PH
Borax: increase PH
3" tablet: increase Clorine + CYA
flush/refill: decrease CYA or CH or anything too high
(special procedure): decrease TA
Cal+Hypo: increase CH

Increase PH: Borax,
Increasse PH + CH: Cal+Hypo
Decreate PH: Muriatic Acid
Increase CYA: 3" tablet
decrease CYA: flush/refill
Increase TA: baking soda + mutiatic acid
Decrease TA: special procedure


Do I miss any ?

Don't need muriatic acid when increasing TA..just use baking soda. Your pH MAY rise but it will only be a very small amount....mine never does when adding baking soda. If you want to raise TA and pH at the same time, use soda ash, or Borax brand washing soda.
