If I am understanding this correctly, it sounds like a bare bottom makes a cleaner, easier to maintain tank. DSB is only a temporary solution (3 year term) to export NO3 and must be eventually replaced. Does it make more sense to keep your DSB in the sump and use a bare bottom in the display tank? You can easily siphon the display tank and, when necessary, you can replace your DSB without disrupting the display tank. Of course, your sump would need the critters necessary to turn/sift the sand. Would it make sense to cover the display tank bottom with shrooms, zoos, etc. to make it more appealing to the eye?
Thanks for any clarification I need here.
