Tatuo 20 Pieces Aquarium Filter Bags Media Mesh Filter Bags with Zipper for Charcoal Pelletized Remove, White and Black

Some of your filter rocks /charol will fall through. Should be a smaller mesh .

Great bag for media. Won't trap tiny particles, and waste.

I used these to keep all of my hardscape together in my aquarium. They work really well.

I only received nineteen bags. I guess I'm fine with that, but I would have preferred to receive the advertised quantity of twenty bags. This was my second time ordering the 20 pack. The first twenty are in good shape after spending a couple of years in a saltwater aquarium. Some of the bags are coming apart slightly at the seams despite never being touched after initially filling them, but they are still holding filter media just fine.

Easy to use

Great item, you can set up media bags ahead of time and install quick when changing filter media. Re-usable and zippers are pretty good quality so they will last a long time. love these things.

They do what they are intended for! The bad reviews is pretty sad. If you can't do math to figure out these holes on these are larger than what you expect but you know basic math to figure out the size mesh you need they work perfect. These are being used for rocks for aquascape hills or used them for filter media! NOT GOING TO WORK FOR CARBON. Look elsewhere. But if your looking for something to hold your filter media or stuff this with rocks for hill scaping this is your go to! I use it for media and scaping hills and raising substrate

These bags are good compared to others I've used in the past but in general zippered bags are way too expensive for what they are. I'd normally remove a star for overpriced items....but...this 20 bag deal is better value than most on Ebay and Amazon.Therefore I've given them a 5 star as opposed to 4 star - I'd say that they were the best I have used so far and pretty good value compared to some of the trash out there. Some mesh bags being sold online literally fall apart when filled with filter media so you can buy these ones safely knowing they will securely hold media and last a long time.I often feature these bags in the series of filter upgrade videos I run on my Youtube channel so I'd definitely recommend them.

I purchased these to hold my carbon and ammonia media in my Boyu tank besides the bio rings, they're quite a good size and quality.Highly recommend 10/10

Exactly what we needed to use for stones inside for our fish tank. Safe for fish good quality

These do the job well, not much to say on them really, they hold a lot of media

Great value for money and useful to have around. Can’t fault them at all.
