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

The metal zippers on the bags dissolved into my water.

Very good

Great Value

have a 1500 gal koi pond which had tea colored water. I purchased two 5 pound activated carbon in media bags and in several weeks have a clear pond.

I have bought several media kits from this seller. Don’t read the negative reviews for which I ignored. I am very happy with my purchases. I rinse the media well before using. Isn’t a negative factor since the amount you receive is far greater than smaller filter media. So of course you would have to rinse them a little longer before use. I will continue to purchase these kits from this seller. Great value for the money and packaged very well!

Used this for our Rainbow Filtration system and looks like it fits the canisters.

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

I have only had these running for a month and they seem to be doing a great job. Perfect kit to start your aquarium, these bags are quite big. Awesome pricing too

Used for monthly filter cleaning.

Purchased this product to help remove the tea color from my pond water. You do need to take about 15 minutes rinsing the package with a garden hose to get all the dust off. It will never be perfectly clean. I have a 2500 gallon pond and just dropped the whole bag in behind some plants. No additional discoloration of the water and already seeing clearer water within the first day.
