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

Goes great with the Cascade canister 1000 filter

Came quickly. All packaged in reusable mesh zippered bags. Although the carbon is really messy, these are all very generous sized bags, and have nice media inside. Great value!!

Very dusty carbon and virtually impossible to rinse. But thats not the real problem. The real problem is that I put the bag in a waterfall type filter. After 3 days, the bag disintegrated. I woke up to find my pond water dark black with a film on top making it look like an oil spill. $50 worth of batting and 4 days later, my pond has almost recovered but the bottom and all rock remain covered with black carbon powder residue.

The ceramic and bio balls are fine but the charcoal is garbage . Don’t expect anything to colonize in this stuff and your tank will be green. It doesn’t even look like charcoal. That’s because it’s not. Also the return window closes in a month and it takes 6 weeks to populate a new tank which takes you past your window for return. Don’t addle with it

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

I really like using them in my saltwater aquarium and in my pond filter I do not use the charcoal

Perfect for small filter, but if youre diy and using a 5 gallon bucket, buy atleast 2.

Does the Job

This is a great kit, and a nice sampler of some good quality filter media. I have used this media in my large reef tank, but I needed some for my office 10 gallon tank. This kit is just the right quantity to last a long time in a small tank like that one. I dont keep it in a media bag, but combined with my

Working well with the filter to keep the aquarium nice and clean.
