I do not think that we can say that this is DSB for sumps. The result may be the same - lower NO3 as rest product. But the biochemical pathways are different IMO. This is a fresh water system from the beginning. Fresh water aquarists believe that free NH3/NH4 will favors micro algae growth and NO2 is highly toxic for fresh water organisms. They need a fast method to take care of the NH3/NH4 and NO2. Maybe this can work in SW too but more observations and experiences is needed.

Agreed, thanks Lasse.

Then everyone got infatuated with Wizbang "reactors" so they could spend more money on their aquariums.
