Do you have a brand name or amazon link for the mineral packets ?

Just a suggestion as well, theres countless 'water recipes' that let you easily do the same thing for a fraction the price. They arent doing anything complicated. Some mixes are simple two ingredients, some go up to several, but all are pretty dead simple.

Lets you fiddle and fine tune things more for your own preferences too.

Third Wave Water is a well known one.

There is a whole book on the topic (2015, with a new edition supposedly coming soon):
