    Price great for quantity

    By HiThere on Dec 15, 2021

    Like one other reviewer wrote, I don't think this charcoal is truly activated. If so, it is exceptionally WEAK! This product also comes without a seal. Besides that, Chewy has been a pleasure to work with and getting this amount shipped out would cost more than 6 times the price any where else (although quality MIGHT just be better elsewhere). I bought 2. I'm on my third shipment of two and will find a way to use it - although not for the purpose I intended. Customer service is GREAT!!! I MUST STRESS THAT. I might not recommend this to a friend since it doesn't seem to perform like activated charcoal I have used in the past. To be fair, I used carbon from coconut and this likely came from Like one other reviewer wrote, I don't think this charcoal is truly activated. If so, it is exceptionally WEAK!

    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.

    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.
