well, there is no "set amount" (shock! right..)
since you are using a dosing pump, am i correct in assuming you are not using this as top off water?
if that assumption is right, get a measure of your
Ca and
Alk, and them start with about 1/2 a gallon a day. after 2 days, measure your
Ca and
Alk, if its still dropping, increase by 1/4 gallon.. then test, and so on.
if you are simply doing it for there other benefits besides
Ca and
Alk, then i would keep to 1/2 gallon a day or less, and confirm its not disrupting your
PH, or raising your
Ca or
Alk to much.
