So I have some extra glass and I thinking of building a 36x36 shallow zoa garden. my plan is to go sumpless with and HOB skimmer and bear bottom. I would like to include a collection of mushroom also. Do you think a Zoa/mushroom tank would work? Would the mushrooms over run the zoe's? I was thinking of having the zoas on the rock structure and the mushrooms attached to the glass bare bottom to make it easy to scrape and frag the encroaching mushrooms? What do you think of this plan?
