Expiration Date on Brightwell Aquatics Products?

[BioRee]

Hi all, just received Reef Code A-P and B-P to start 2 part dosing for my tank. Before that, I would like to know what is the shelf life for these product? I didn't see any expiration date printed on the label. The only thing I found was the lot numbers:

Lot #: 1050115
Lot #: 1682614

I would appreciate if someone knowledge of the product to let me know of the expiration date or when it was manufactured according to the lot #. Thanks.
