I have purchased the bags , rocks , food, plants and various sponges. I feel very confident when i order from Aquarium Co op. Great shipping. Very fast and always good.

This bag is just the right size and very inexpensive.

Got a few of these for adding crushed coral etc to my canister filters. Good quality and a little bigger than I was expecting.

Does the job good price love it

Way to small. Was looking for about double the size.
