Yeah, what he said.

It must reach a breaking point when you crank it up too much. Some things rock around more than others, so its up to you if you think it would be worth it in your tank. My gorgs and leathers are dancing, but my cartilaginous macro is at a stand still.

IMO, totally worth it. The NPS seem to appreciate it too, the wavebox and appropriate foods are a good combination since I don't have a fridge feeder. Maybe that will be next...
