You make a good point. There is that risk of having most of my denitrifing load remote to the display. But I hope to have a mature sps display with some open space above it. All in a 50-60g cube. Thankful power outages are very rare where I live.
The recent thread on GAC and dissolved organics had Matt Waddell mentioning the at least one of the displays at the cal Academy of Sciences is supported by remote bioballs.
There seems to be some nice sps displays started with dry rock alone. So one may conclude that, excluding a comparison of surface area, it doesn’t matter what the composition of the biological filter substrate is.
There will be rock in the display but minimally so. So in order to have a decent bioload I’ve got to plan for remote.
