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

Excellent value

Love it!

Does what its meant to do.

works great in the Fluval 406. Cheaper than petco

Good product used it in my sunsun 404b and my sump works well would buy again

Very easy to replace existing filter components, a few hours later my pond water is crystal clear!

This is just what I needed to finish an Aquarium filter I was building. I am very pleased with this item!

This will be the main product and company that I purchase these from, no longer buying from the local fish store. Value is great for the price.

excellent product

Ease of use
