How much Purigen

I bought a 100mL bag of purigen for my shrimp tank. It says to use one bag per 100 gal, but I'm afraid to open the bag. Do people just toss a whole bag in? I might like to use some in my other tank to get rid of tannins.

And a smell is normal for new purigen, right?

Yes toss it in the filter, I use a bunch in my canisters

Yes smell and slightly wet is very normal, run it under some tap water before putting it in

You never open the bags they come in?
if you buy purigen in a bottle, you can pour the dosage you need into a media mesh bag otherwise the ready made bags are just plop and recharge
I bought the 100mL bag of purigen for my shrimp tank too. Just kept it in its bag and replaced my HOB's carbon with it. Everything is fine (it's a 30 gal tank too lol).
Yes, you can put the bag right in your filter. I use it on a 12 g with no issues. I'd rinse it off first just to get dust and debris off it.
I pre-rinsed my purigen in prime water before using them.
