Great product
By JunoLouise on Dec 11, 2020
Sadly, I no longer have fishies since we hit the road in our RV full time. I use this charcoal to stuff old socks to stash in closets, drawers, and cargo compartments, and it works great for that. The bay where we stow our pupper supplies no longer reeks of old dog foot. LOL. I also use it in the bottom of our planter pots.

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.
