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

thought they were bigger than that. Got the wrong size, but I guess it does ok for the size

Excellent value

It is exactly what it says works great for my canister filter

what can I say its activated charcoal to help eliminate smell and enhance clarity in a KOI pond

looks good..

Does the job

As advertised and pretty fast shipping. Would recommend

I give it a 5 star, just what I was looking for.

IT DOES WHAT IT DOES

Great product !!
