Any Chemists out there? Seachem's Fresh Trace vs. Kent Marine's R/O right?

[michaelg210]

Can anyone tell me the difference between these products, or even Seachem's equilibrium and Kent's R/O Right? I am using R/O water and wish to know what is best for restoring minerals, trace elements, and general water hardness..... i know nothing about chemistry, so simple explainations if possible pls. Thanks in advance:

Kent Marine » Products » Liquid R/O Right

Seachem. Fresh Trace

Seachem. Equilibrium

Kent Marine will not disclose anything beyond the MSDS which simply has:

<B>

Ingredient Name - (CAS Number) - %​

​

​

CALCIUM SALTS (10043-52-4) < 0 - 20​

CARBONIC SALTS (144-55- < 0 - 20
MAGNESIUM SALTS (7786-30-3) < 0 - 20
SODIUM SALTS (7647-14-5) < 0 - 40
SULFATES (7757-82-6) < 0 - 20​

I even emailed tech support, in short their reply:

This is the extent of what I am able to give out except that a major part of the salts in the product is sodium chloride as this is the highest occurring salt found in nature. The specific ingredients are held proprietary. I am not even allowed to see the breakdown formula.

(Bold is mine, but Seachem claims Sodium Chloride is bad)

Elemental potassium is present at a concentration of 195,000 ppm (19.5%). Archaic fertilizer laws force us to list potassium in terms of equivalence to a material that is not present (K2O) rather

Unlike competing products, Equilibrium contains NO SODIUM CHLORIDE. Both sodium and chloride are not rapidly depleted elements in a planted aquarium, and, in the case of chloride, can do more harm than good. Competitors’ products generally contain primarily sodium chloride (because it is inexpensive),
