Great Product

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!
