I have a BioCube 14. Currently stocked with two clows, a yasa goby, pistol shrimp, and various zoaz and acans. I want to keep the stock look of tank, and I am considering either purchasing a media rack for the middle back chamber and configuring it with chaeto and filter floss, or purchasing a Sapphire Aquatics NC12/BC14 Protein Skimmer. I know the media rack will be the cheaper route, but I am not concerned about cost as much as benefit. So does anybody have and opinions on which would give the most benefit to waste removal and in turn water quality?
