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

This set was a perfect starter kit for my filter. It includes everything youll need and all three mesh bags are still holding up with no ripping or tearing.

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

Great price, as pictured.

This is a good thing to get for first time! I love it! Thank you for the fast shipping.

Had to repack medium because of metal zipper closures. I’m using this for a saltwater tank.

Great as always. I have been getting these for our fishes from this seller. This is our second or third order. My goldfishes are very very happy and this lasts us for 4 to 5 months. Fish tank water is very clean too if I may say so. Thank you CNZ Aquarium. I recommend this product and this seller to everyone.

Makes a huge mess. Water became very cloudy after I added the bio-balls.

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.

So thrilled with my purchase. Never have to buy the disposable ones again. I was hesitant when I saw the other reviews, but I’ve had no issue with these and had nothing but clear water since I got them. I only use two of the bags at once in my 65 gallon filter. I switch between the media. I soaked it in hot water for about 20 minutes before using and rinsed a couple times.

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