CNZ Media Filter Bags Activated Carbon Charcoal Aquarium Fish Tank Pond Canister Filter, 4 lb., Black C4PK

Small enough to fit almost anywhere and gets the job done

It is what I needed for my canister filter. Thanks

Coal pellets in good condition, miminum amount of dust,mesh bag looks to be good.time will tell.

These little bags of activated carbon charcoal worked wonders in my aquarium. Within a short period, they effectively removed the water's unpleasant odor, colors, and organic pollutants. The water became crystal clear, making my fish swim happily and visibly content. I was thrilled to see that the product lived up to its claims.One thing I learned while using these filter bags is not to overload them. Using one bag for every 60 gallons of water proved to be the sweet spot for optimal results.

We had been having trouble with our turtles water getting dirty extremely fast. I decided to change the type of charcoal we had been using and tried CNZ filter bags. Wow! What a difference!! The tank still has particulates but the water is now clear for a much longer period. Wish I had tried these earlier. The bags also wash out extremely easily.LOVE this product!!

Great value. Easy than buying from the pet store. The bags have zippers so you could fill and reuse them.

Help with all kinds of filtering. They are easy to clean and seem to recharge in sun very well. I love them for pond filtering in temporary setting. I just lay my pump intake on them and let them filter. My pond is crystal clear since I started using them

Use For Media And Put In Water Filter For Red Ear Sliders.

If you have a 4 feetter or more with preferably a sump. close your eyes and buy it.

I like it. Got it at good price.
