Rated 1 out of 5 by from No small size??? Why do they not have small size bio bags? I would like to have larger than 2 pack small filter cartridges.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from They USED to be great ! I have been in the hobby for close to 30 years and have set up quite a few tanks for friends. I have used and suggested this product for years but now they have gone down hill so bad that they are terrible. They used to last so well that you could rinse them out (keeping the bacterial alive in the filter) and reuse them. Tetra even used to have a PRO model. If they still offered that I would not be so upset because I would be able to at least purchase something for the filters that I have running. All that is offered now is one products that is poor quality. Its a real shame that they are messing up a product that we have used for years and were happy with.

Rated 1 out of 5 by from Quality has gone down They changed the material and these inserts breakdown far too fast. The old version lasted a lot longer and would keep me a customer. The new version has me looking for another filter. To lose all the good bacteria that is in these inserts is frustrating.

Rated 5 out of 5 by from THESE CLASSIC FILTERS ARE STILL GREAT! I first used these cartridges 24 years ago in my Whisper filter on my first tank. And I still use them! They are easy to use and they trap a lot of dirt and keep the water clear. They are easy to assemble and you can add more carbon or other media to them when needed. They can cost less than $2 per cartridge when bought in the unassembled packs. They may not seem as "modern" as some newer filter cartridges, but if its not broke why fix it! They have been around for years because they work!
