CNZ® Aquarium Filter Media Kits (Double Pack) - Activated Carbon, bio Ball, Ceramic Ring

i little smaller then i hoped for so i use both together work great

Love it paid half as much as I did at the local store for one and so accurate!

Great buy! BUT.... the carbon is really just charcoal :( You can never rinse off the black. So its of no use.

Very good

Used for monthly filter cleaning.

Goes great with the Cascade canister 1000 filter

This will be the main product and company that I purchase these from, no longer buying from the local fish store. Value is great for the price.

Very nice product. Each item is bagged by itself and is in a zipper pouch to adjust sizing. Well done

Excellent price for this combination of items!

Does its job and i saved money! Definitely worth buying in bulk instead of every few months!
