Yes, you can put it either in your HOB

You can either buy it in bulk up to 1000 ml which doesn't come with the mesh bag or in 100 ml increments which come in a fine mesh bag.
If you buy it in bulk make sure you put it in a fine mesh bag
before using. More info is on SeaChem's site
Considering the 100 ml bags treat up to 100 gal
for up to 6 months it should be all you need.
You can regenerate it but I've never tried personally.
