Interpretation of MSDS
Currently, I'm trying to reproduce a pool chemical, "BioGuard Mineral Springs Renewal" because the price of it is outrageous, $40USD/4lb bag, one bag
per week. I found the MSDS online and it lists all of the ingredients with a range of percentages(it doesn't list that the remainder is sodium
chloride but I know that from the package). However, some of the percentages range as much as 20% by weight, is this the allowable range, or is this
to prevent people from reproducing it?

Do you have any of the product currently? Maybe you could buy a bag and attempt to analyze it, still save money in the long run. Besides, there might
be more ingredients. Those are just the so-called "hazardous components." There may be more than just sodium chloride making up the remainder.

I already bought a bag and it list the ingredients as sodium bisulfate, sodium chloride, boron salt, organic acid, and aluminum salt.

They list ranges usually.
In your case, 15-35% NaHSO4, etc.
I'm not sure why they aren't more precise. Maybe it is a matter of quality control being weak.
Yes, companies just throw together chemicals and add inactive ingredients to bulk it up and add color, make a pretty label and just sell it.
A good example is Windex (pretty blue color) and Draino (pretty green color added to NaOH. Not sure why they add 1% NaCl).
Every clone of Windex also adds the pretty blue color. Some of them add green coloring.

We must attach the electrodes of knowledge to the nipples of ignorance and give a few good jolts.
Yes my evolutionary friends. We are all homos here.

Well I guess if that's the case then you'll probably be fine mixing it with those approximations, and then seeing if it works like it should.
