Brightwell Reef Code A/B DRY form - Expiration date or Lot No?

[reef-rc]

I have both brightwell reef code a/b in dry form in a bag and was about to use reef code b-p for alkalinity and noticed this on the bag "EXP011222". Is this the expiration date? I did noticed the "EXP011222" is RIGHT ABOVE the "LOT NO" so I am confused by this. Or is this the LOT NO? Thanks.

This looks like an expiration date. Some brands will use the exp date as the lot number as well. If you bought this from us recently, please feel free to reach out to our customer service team and we'll take care of you.

That said, dry supplements, especially if stored unopened, rarely go bad. For example, we say that the dry BRS two part powder has a nearly indefinite shelf-life if stored in a dry place. I personally wouldn't hesitate to use this as normal.
