Q: What is the amount of the electrolyte (i.e. 1 quart)?

You have to select the size you want in the drop down list. This electrolyte is sold in 2 quart or 3 quart bottles.

Q: Hi, is the price was per quarts or per box? thanks.

The price is each. So the 2 Qt option will come in one 2 quart bottle and the 3 Qt option will come in one 3 quart bottle.
