my understanding (from reading this and other expert forums) is that a remote DSB does not work because the DSB does not get enough food to sustain a reasonable infauna. Why would a DSB in a bucket work, when a DSB in a 25" X 15" refugium would not?
IF we had a buckets worth of sand in a small refugium, would that make the small refugium DSB usefull in reducing nitrates, or does this have something to do with the configuration of DSB in a bucket?
Thank you for the help in advance.
