I have put these in all my HOB and canister filters seems to really be doing a good job and decent price

Good amount, great for filtration!
My order arrived well packaged. I bought these to add to my Aquaclear 110 HOB because I decided not to use the charcoal insert. I have not added them yet, but expect them to work great and fit nicely!

Good deal
Too many for my hobs. Bought smaller bags to use on 2 of my aquariums. That will work wonders. Rinsed. Soaked. Put in one hob loose while I wait. Definitely helping with the bioload.
