I've purchased this 4 lb canister several times. The first in mid 2011 and it was excellent, dark rich green and smelled slightly "fishy" but also had a good smell. The second canister I purchased in August 2012 was slightly off and had a bit of a harsh or strong aftertaste and a bit of a pungent kick and was a darker green a bit more black, it just didn't seem as high a quality as the first. I just received the third and I'm sad to say its got even worse. The color is almost a dark brown green slightly blackish and there are visible gritty particulates in the spirulina. It seems like this may be a bad batch or that quite possiby Now Foods has compromised quality by choosing a poor supplier to offer these lower prices. I have contacted iherb about a return and refund. I will request a reship to see if this was just a bad batch.
