When filled about half full with activated carbon or carbon/zeolite, they fit perfectly inside the filter housing and keep the water clean for about two weeks. They have held up well and clean up easily for reuse. Would buy again. Review: best media bag - These media bags are great. Quality is A+. No you can't use them with GFO but you can use them with phosguard and small particle carbon. Can't bet the price for an 8 pack, I'll be buying more of these when needed. Also buy their filter socks they have a great price for the quality of them. ## Features - Versatile Compatibility: Fits small filter media, especially activated carbon, zeolite, peat, crushed coral, and other types of granulated filter media. Will NOT work for very fine resins such as Purigen and CupriSorb, for these use our Extra Fine Mesh Media Bags. - Durability and Reusability: Easy to fill and empty with a top drawstring design. Washable, durable, and reusable. - Optimal Water Flow: Place the mesh bag filled with your chosen media in flowing water. Optimal hole size allows water to flow freely around and through the media. Adjust bag length by partially filling, folding, and tying it off. - Secure Closure: Custom bags prevent loose media from damaging water pumps or filter motors. Safe for both freshwater and saltwater aquariums. 🐠🌊 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0737Z7DQY | | Best Sellers Rank | #9,887 in Pet Supplies ( See Top 100 in Pet Supplies ) #61 in Aquarium Filter Accessories | | Brand | Aquatic Experts | | Brand Name | Aquatic Experts | | Customer Reviews | 4.6 out of 5 stars 731 Reviews | | Global Trade Identification Number | 00679360098844 | | Item Form | Granules, Pellets | | Item Weight | 0.31 Ounces | | Manufacturer | Aquatic Experts | | Manufacturer Part Number | 7.59615E+11 | | Model Number | 7.59615E+11 | | Number of Packs | 4 | | Pet Type | Fish | | Target Species | Fish | | UPC | 679360098844 | | Unit Count | 1.00 Count | ## Product Details - **Brand:** Aquatic Experts - **Item Form:** Granules, Pellets - **Item Weight:** 0.31 Ounces - **Manufacturer:** Aquatic Experts - **UPC:** 679360098844 ## Images ![Fine Aquarium Media Bag, Durable Drawstring Bags for Fish Tank Filters, 450 Micron Mesh, (Fine, 3"x 8" - 4 Pack) - Image 1](https://m.media-amazon.com/images/I/81iN+wnGm4L.jpg) ## Available Options This product comes in different **Pattern, Size** options. ## Questions & Answers **Q: What micron size is the mesh?** A: Our Fine mesh media bags have a 450 micron rating.
