Good buy but a lot of work
By Kadotah on Jun 12, 2020
Great deal for the money but be prepared to spend 20-30 minutes rinsing then gravel. There’s an unbelievable amount of dust in the package.

Activated Carbon
By Ktorlando on Dec 28, 2019
Works great in any tank size, more cost effective to refill and wash out the bags in filters rather than the pre-filled bags. Lasts much longer with a greater volume when you fill and refill yourself.

Great Carbon
By Barbara on Feb 2, 2019
I use this carbon mixed in with the cats’ clumping litter for safe odor control. It also is useful in keeping items dry to prevent the growth of mold or mildew.

Amazing stuff ..
By Deodorizer on Jan 5, 2019
I was given a little hint to use this in my litter box. And when I say this stuff works! Wow. No more stinky litter. I use a scoop every few days and it's is a life saver.
