Don't be worried so much. A slight smell isn't worth stressing over. A strong smell is a warning sign.

I ran out of reagent myself for about 5 days earlier this month. I test every day. I just kept adding my typical 1/3rd of 121oz 8.25% each day. Next test after getting my package shipment was right where I expected.

If you order again, use the Amazon store here and the forum will get a small piece of the sale.
