DSB's create an anaerobic space for denitrifying bacteria. By limiting nitrogen via these bacs, you limit the the bacs dosed in a ULNS. Same reasoning why GFO should not be used.
Also, DSBs can accumulate nutrients and cause algae issues as it leaches out due to the ULNS lowering nutrient levels in the water column.

every tank is different, but FWIW we dose .75mls on our 90g.
