Review on BiOrb Service Replacement Airstone Bundle by Kim Smith

This product is a lifesaver for my aquarium it's much easier to replace the airstone than an entire air pump. Through trial and error, I found that these replacement stones work best with my BiOrb aquarium and help to keep my fish happy and healthy. The only con is that it can be tricky to replace the stones without getting water everywhere, but THATS more of a user issue than a product flaw. Overall, I'm very satisfied with this purchase and would recommend it to anyone in need of aquarium pet supplies. .
