I'm stuck with this product/system for now by Adele from Los Angeles, CA04/16/2014
What a mess the bio bag has proven to be! I am stuck with it because I unknowingly bought a filtering system for my 5 gallon tank that requires this. You have to make up the filters yourself, and try to pour the little bits of charcoal in without spilling them all over the place. I would much rather purchase a pre-fab filter that won't make a mess of things. When this filtering system dies, NEVER AGAIN! I will ad, however, that entirelypets.com did an excellent job. Product was delivered quickly, and in excellent condition.
Best prices I have found by andi from cape cod,MA12/01/2012
These unassembled bio-bag cartridges are just as good,if not better than the much more expensive pre-assembled bags.
They work really good in my turtle tank filters.
serves it's purpose by ndonsomd from md04/30/2014
We use these bio bags with a whisper filter in our aquatic turtle tank. We use two filters and they server their purpose. We like these because we can reuse the plastic part of the filter and it reduces waste.
Good purchase by Dulcinea10/27/2012
These filters are easy to assemble and work as expected.
good product by bobe from Charlotte, NC05/05/2012
the product is much cheaper than the pet stores because you have to do a little assembly yourself. very simple to assemble, definitely worth it for the savings.
