    FINALLY FOUND IT

    By HAVILAHSPRINGS on Jul 22, 2021

    This is a great product and at a SUPER price, very happy with the transaction. I tried to find this in my local big name pet stores that say they carry it, but don't. The shipping was a different story. One of the major shipping agencies had my orders sit in Las Vegas for three days.

    Good stuff

    Been using this product for 20+ years, it's cheap and does the job. I use it in a bag in all my canister filters and never get spikes in ammonia levels.

    Mandatory for my big goldfish tank!

    By on top100Contributor

    Goldfish are notorious for producing lots of ammonia. This stuff along with activated charcoal pellets, inside my 350 gal/hr Eheim canister filter, keeps my 75 gal tank clear and non stinky. I've found putting the carbon and ammonia reducing media into mesh bags, shortens my cleaning time for full filter system breakdown and rebuilding. With media inside bags, it is simple to thoroughly rinse off any crumbles and dust, which could damage the impeller and cloud the water if this step is omitted. I'm glad this stuff comes in a large container, as I need more than 1.5 cups of each media type on every filter maintenance session. Couldn't imagine keeping goldfish without this stuff!

    Works well

    Can add this to filters since most filters don't add this to theres. Really does help keep ammonia down in my tank.

    I use a blend of 25% zeo and 75% carbon when needed - works great for me. And with Chewy the shipping is fast
