I ordered this for my sister’s tank and this thing doesnt filter at all, it was only in for less than a week and left the tank worse than without a filter.
Different product should have a different name.

I ordered these "Tetra Bio-Bag Disposable Filters" because they had the same name and looked just like the previous ones I bought. However, these require assembly and the others did not. It turns out it only saves 50 cents per filter, and the assembly is messy, confusing, and time-consuming. They should have a different name for a different product. I would never buy these again.
Excellent for my 7 fish tanks

I've used the bio-bags for years. They do the job. The price and fast delivery service at Chewy is top class...
Used This Product for Years
on Jul 13, 2020
I have used this brand and type of filter for 7 years and the same brand for 9 years. Works like it is suppose to, especially the carbon. Helps with odor and clearing the water. Ordered these, took a good while to get them due to the covid pandemic. Not complaining about that, I understand. Still got my products and using them
Got What We Ordered; Shipping Slow, Expensive!

We ordered. They sent us what we ordered and none of that free shipping nonsense, either. It also took longer than it would normally. They warned us. Age of COVID. Nothing great, nothing wrong. Three stars, two off for so-so pricing and costly shipping. Did I mention Age of COVID? This is what there is.

Tetra filters are the only ones I have ever used. I was thrilled to find a 12 pack box of them. I have a large aquarium and need to change filters often and this saves having to keep ordering them so often. Thank you, Chewy once again for your great products and service.

This product works like it's supposed to. Unfortunately chewy did a not so great job packaging it for shipping so it was pretty beat up when I got it.
trying something different.

I have not used these yet. that's why only 3 stars. will update after using them. They look like they should be easy to put together.
