10 Pieces Aquarium Filter Bags Fish Tank Media Mesh Filter Bags Net Bag with Zipper for Charcoal Pelletized Remove Activated Carbon, Biospheres, Ceramic Rings

Work great

So far, bags have held up very well and have not had to replace due to tears or holes. Easy to rinse filter medium without stuff flowing out of mesh.

Zipper breaks too easily. Sometimes it's an easy fix, sometimes it is completely broken.

These are very easy to clean and easy to use bags that anyone with a fish tank should have around.I using them to hold carbon and bio media in a cannister filter as well as two hang on back filters. They are more suited for a cannister but still work well. I also have a small amount of crushed coral to improve the KH for my shrimp and snails. It holds that well also.You get a nice amount for the money and overall this is a great value.

Makes rinsing your media so much easier and kids it together.

Bought these impulsively along with some crushed coral for my aquarium, got lucky, holes are small enough to hold all the little pieces of crushed coral and durable enough to rinse and boil it in too.

Excellent

A little too thick in my opinion but my biggest issue is the holes. Theyre fairly large for aquarium media.

Bought these but was only given the white bags. The holes in the white bags are much larger so many things fall out.
