Review: Just what I needed - Works just as i needed! They close nicely and do not feel cheap. They hold the amount needed for my 10 gallon tank nicely and safely. You get several of them so its a good deal. Safe for aquariums just make sure you rinse before adding! Highly recommend!
Review: Use within manufacturers recommended tolerance - Functions well as storage bags for small items that need visual rapid identification or to contain aquarium health products requiring high flow.

## 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. 🐠🌊

### ⭐⭐⭐⭐⭐ Use within manufacturers recommended tolerance
*by R***R on January 25, 2026*

Functions well as storage bags for small items that need visual rapid identification or to contain aquarium health products requiring high flow.

### ⭐⭐⭐⭐⭐ Perfect for water changes!
*by O***O on May 29, 2024*

I use these 5x9 High Flow bags over my gravel-vac (secured with twist tie) or attached to the hose outlet of gravel-vac. Small critters like Ostracods (seed shrimp) will flow through, but baby shrimp and tiny snails will not... Perfect sized mesh to protect my drains and local waterways! These bags are worth the price, made in USA and are quality. My original ones are still holding up, the only reason I'm ordering more is because I haz more tanks (it happens) :")
