What a lame response to make in Friday night, I know, but I'm busy
tasting too many bottles (of spirits) I brought from NH this week.

Disodium and tetrasodium EDTA have different degrees of acidity and
one should check the original formula before buying them. Either one
can be used if you are willing to adjust for the difference in
acidity, but, buying the form specified in the formula is the easiest.

Non-lame responses may have to wait for Monday after lunch hours...
