Tetra® Whisper Bio Bag Disposable Filter Cartridges
No small size???
Why do they not have small size bio bags? I would like to have larger than 2 pack small filter cartridges.

Horrible idea that doesn't work
I grabbed what I thought was a box of 12 regular Bio-Bag filters. The box says in large letters: "Bio-Bag Disposable Filter Cartridges." Nothing about "must be assembled." "Easy to assemble" is in small print further down the box. These are the messiest worst things ever. I'll never buy another box. No matter how careful I am I wind up with "carbon" pellets all over my counter, in my sink, all over the place--either the old ones as I remove the frame from the old bag or as I'm trying to put the new pellets in the new bag. What a horrible idea.

These are the only wafers my little plecos will eat. They are just the right size for rubber lipped plecos.
