Great little media bag and a wonderful price. This is a great biological filter addition.
I'm a newby to all this and learning as I go, but the bio bag & beads are a super addition to my filter. Such a great container for the beads.
I use them on the end of the gravel vac, to protect tiny fry and shrimp, I fill them with crushed coral or bio rings, etc, etc, etc
Great working product makes my job easier! Good pricing an very
