Wow, looks awesome! 11mL sounds low to me; I dose more than that daily in my 22g. But your corals look healthy and growing. Do you do frequent water changes that replenish the Ca, Alk?
I like those frags on the tonga branch up top that you were worried was too high. Think of it as a much nicer alternative to a magnetic frag rack stuck on the back wall. The open water under that branch looks very cool and highlights the awesome branch itself.
Still weird about no luck with shrooms and zoas. Is your water too polished?
