In a month or two Ill be changing my sumps DSB to Miracle Mud. Iv got a 12" x 4" weir with a 10" tall lower stand pipe and it's crossed my mind to setup a new DSB in there. My return pumps turn over is about 7000lph. Do you think this is a good or bad idea? Pro's & cons? Is it a big enough area to have an effect on the system?
