I’ve used this filter bag for three months now and haven’t seen any rust. The plastic zipper is sturdy and keeps the media secure. My fish seem healthier since switching from the old rust-prone bags.

It works well with my carbon filter. The micro net holds the carbon tightly and doesn’t let it fall out. A small improvement over the old filter bags I used before.
