I just opened a brand new container of Purigen, and when I broke the seal, it has a yellow-tan color and a slightly vinegary smell. Anyone ever experience this? I thought it was usually white and odorless. I haven’t used it in a while and just decided to order some.
What was the verdict? Did you use it. Me too! Mine is orangey in color. I used it anyway. There is another thread that mentions Seachem said the color can vary from white to tan to Orange depending on batch.
