Premium Activated Carbon, Aquarium Carbon for Fish Tank Filter, Aquarium Filter Media, Granulated Charcoal for Fish Tanks, Activated Charcoal Bulk (5.5 lbs with Fine Mesh Bag)

You can tell the quality right off the bat. So much less dusty than other leading brands, rinsed clean almost immediately. I like the smaller granulars as it seems like fit does a much better job filtering the water through it and my tank is amazingly crystal clear. Will always buy this going forward.

Charcoal does its job keeps aquarium water crystal clear either use bag that comes with it or purchase extra fine bags I used my fine media bags and charcoal was coming out now that issue solved will definitely purchase again.

Well packaged, quick delivery. Packaging had no leakage of carbon at all. Very sturdy and full container.

Seems working good

The cleanest carbon i ever used, this stuff is plug and play it's rinsed so we'll that a pre rinse before install produces no black ash residue at all. Highly recommend

Hyundai evacuation canister repack. Perfect amount of charcoal for my purpose. Also used aquarium charcoal matting material. Cheap fix compared to new purchasing new canister.

I kinda wish the crystals were a little bigger, but it does what it says it does. I have a 40 gallon tank with a lot of wood. Water became dark brown, even after allowing the wood to seep; the water is now a light tea color. I integrated the activated carbon into the filter and the water stays relatively transparent/light brown. I just have to replace/rinse the carbon once every few weeks or every other month. Really happy with the purchase overall.

Bag was too small
