After eight years my old Tetra filter died and I just purchased a new one that utilizes the bio-bag cartridges. They work very well!

Nothing wrong with product but came in a cardboard box without any instructions. Looked like it was packed by a 2year old. Pieces just thrown in.

These filters are very easy to assemble and I found them to be very effective at trapping a lot of my aquarium's waste. If you have an aquariums with a lot of fish and cloudy water, I recommend rinsing off the surface of the filters every 2-3 days for optimal performance.

I have 2 systems that use this filter, it's pricey because of the little tablet you put in the middle, "Stay Clean Technology" my butt, not only do you have to assemble it but it is no different then the bio filter w/o it. It It should be cheaper since we have to assemble it, like anything else we by. Save your money and buy the bulk pack w/o stay clean technology, it works the same, tablet is just a buffer which you already have in some chemicals you add or Aquarium Salt, pillow softeners are cheaper and work great and last longer.
