Tetra 26158 Whisper Bio-Bag Cartridge, Medium, 1-Pack

I bought other bio bags that didn't have enough plastic inserts. You can reuse the plastic insert and clip on this bio bag for other bio bag filters.

I bought this filter for my six gallon tank, they seemed to be falling apart already so I put it into another bag, went ahead and bought another filter, because of these bags, the last one I used, not from this seller, also fell apart and some of the inside particles got into my tank,what a mess! I didn't return them b/c they are so cheap.

It is totally wasteful. After a month or two I usually clean the filter cartridge.

This bio bag is unable to be reused. It simply tears apart after I rinse it off to

use it again. This maybe the only brand that makes you buy cartridges over and over.
