This carbon pouch is great cuz it fits in old aqua clear filters and new ones. Once you open and rinse you are good to go. You did have to tuck in extra material of pouch. I wish they would make alittle shorter but, still fits pretty good. Last for about a month with 5 med size tropical fish.

Nice idea for more thorough aquarium filtration

I really like the idea of how this is part of such a seemingly complete aquarium filtration system. I think fish will be healthier because of it. It's easy enough

I really like the idea of how this is part of such a seemingly complete aquarium filtration system. I think fish will be healthier because of it. It's easy enough to use with the appropriate filter housing.

Fits great

The charcoal bag fits great in the new Fluval AC50. It rinses easily and fit the tray perfectly. The tank water cleared up quickly after a major clean.

Love it

Was a little unsure about trying a new filter but so far I’m really loving it. It also seems like the filters will last a bit longer before needing to be change

Worked as it should

The fluval system can not handle a 50 gal tank. That being said the Carbon work as it should. It needed to be changed soon than it should. A small tank like 20 gal

Simple replacement

Bag fits neatly into the filter stack. Very little carbon dust when removing from packing. Securely stacks in filter for decent water flow through the media.

Don't last long

Fit the filter but don't seem to last long. And don't take the smell out of a cycling tank.
