As some of you may know I'm in the process of a slow tank build. As a result, I've been carefully selecting everything I will need. I've been thinking of doing biopellets but haven't heard about them in a while. When the craze was going on, I know a lot of you were running them. Do you still run them or did the results start to vary over the long run? If your still going strong, what does your rig consist of, how much is the cost for the whole setup (guesstimate), and cost to keep them running? Thanks.
