There used to be 5 stars, there are purigen, there aren't that many of these bags. I've been using Purigen for years and have no complaints. Works great, purifies water, charges. The only complaint I have is that Seachem seems to have resized the bag. They used to be the perfect size for my fillet basket, now they're longer and uncomfortable. Also the new bags skip the medium like crazy, even after multiple flushes they cloud the water from the powder. I don't know why you should change the good for the bad. Please do not add pictures.
