Review on OASE Indoor Aquatics Hel X Biomedia by Val Bailey

After I put it to the test I was impressed with how quickly the Hel X Biomedia worked to establish a healthy ecosystem in my aquarium. It kept my tank clean and clear with minimal maintenance required .The only downside was that it took up a bit more space than other filter media I've used in the past. Overall, I highly recommend this efficient biological filter media for any fish or aquatic pet owner..
