    Good buy but a lot of work

    By Kadotah on Jun 13, 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.

    I use this in the filters in my turtle tanks. I love the nice big sized container because I change it in 3 tanks every two weeks.

    Large container for a great price

    Use this in my house plants. It's nice and fine and much better buy than the little container from the store.

    Great product

    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.
