Brightwell had (maybe has) some incorrect values for the potency of its magnesium product. Jack Kent corrected some I pointed out on their website, but there may be problems elsewhere on labels.

It is good forever.

For dosing, assume it is anhydrous magnesium chloride in this calculator:

Still has terrible errors in their advertising.

They fixed their web site:

http://brightwellaquatics.com/products/magnesionpt.php

Ingredients
Magnesium sulfate (anhydrous), Magnesium chloride (anhydrous)
Guaranteed Analysis
Magnesium (min) 24% (240,000 ppm)

But not their advertising at resellers:

https://www.marinedepot.com/Brightw...-Brightwell_Aquatics-BW01118-FIADMIDA-vi.html

Guaranteed Analysis (by weight)
Magnesium (min) 43% (430,000 ppm)
Ingredients
Magnesium sulfate (anhydrous), Magnesium chloride (anhydrous)
