Comments: This product is fantastic. Its very easy to use and it works great. All three of my saltwater tanks use the Rena systems and all have the bio chem zorb filtters. Ever since I started using this product all my tanks are crystal clear. I love this product and I highly recommend for anyone who keeps saltwater aquariums. Yes, I would recommend this product to my friends.
