I've bought these many times in the past. This is my review. They flat out work. On top of that, quick shipping. You can't go wrong.
This quantity that you get for the price is awesome.
Very good value you get for money also very fast shipping
Works great with my filters on all my tanks.
These Bio-Rings are a necessity for a healthy and happy aquarium! In my opinion anyway.. And these bio-rings from aquarium co-op are such a great deal! I was previously purchasing the aqua clear bio rings and they are much more expensive! although the aqua-clear bio-rings work amazingly as well they are much smaller in size and they are quite a bit pricier. Still a great product just not as great as the larger and less inexpensive ones from aquarium co-op. Even with having to purchase the bags to put them in you still get way more bang for your buck! Thank You Aquarium co-op!
