This video is a review of the Eco Bio Block. This product is also commonly referred to as the Eco Bio Rock. This is a great product to have in any aquarium. You can purchase this product on Amazon or at the company's website at www.onedersave.com.
I want to apologize for the background clicking it is my cameras focusing system going through the internal mic.
I will be purchasing an external mic soon.
