Help Me Figure Out What These Bags Are, Please!

I used these years ago in my saltwater setup but I completely forgot about them.

I have two bags, one with larger beads that I believe was a Nitrate remover and the other with smaller beads, I think, was to remove Phosphate.

I can't remember what the brand or name of the product was, or how to clean them.

If I recall, I would soak the nitrate beads in 10% bleach once a week or so to reset them.

I can't remember how effective they were. I know my setup had no diatom algae problems.

I attached some pictures to see if any of you recognize them. Any help would be appreciated. Thanks!

Yeah, it's purigen! You're only recharge them when it's turn dark brown color, white = good and black/brown = need to recharge...usually every month not every week
