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)

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

I order this item for the second time. Good quality and enough for a long time.

This product lasts long and works just as well or even better than normal tetra. The tetra bags always clog up on me and this bag rarely does. Would reccomend if you don't want to spend more money on tetra filters as it (I think it was only the larger size, don't remember) came with a bag. Its been 3 months and I haven't had to refill the bag. All I need to do is rub it down with a toothbrush from time to time and it's fine.

It's to fine in course media, which for best results placed in-the-sump use. It works well, but this type of carbon exhausts quickly. I prefer larger diameter carbon for longer results (I have a 92 Boew front reef tank).

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.

I am using it to filter drinking water. The charcoal and polyester filter floss is packed tightly so the water, at 40 psi supply pressure, is forced through it. With other charcoal products, after replacing the media, and even after washing the new charcoal, I have had to run a lot of water through my filter until I stopped seeing black specks in the filtered water. With this product, even though it is finely ground, and without any pre-washing, I didn't see any black specks. Of course, out of caution, I ran a few gallons through before drinking. It tastes fine. I recall that this product is also sold in a 3 pound jar. The reviews seem to be separate. Amazon should merge them. Readers should look at both.

Very easy to use product great buy

Good price and but I have not used it yet.
