I can’t seem to decide on which fish to add

Anyway, in the meantime I’ve started a routine of adding Acropower at the lowest recommended dose. We’ll see how it goes. After sticking to a consistent schedule of adding Reef Chili, I have definitely seen improvement. Zoas that were fading away and shrinking have rebounded, and SPS have coloured up. It’s been easy to see with the Red Diablo for instance, that became a pale pink but has now deepened. I swear I see a hint of purple in the bonsai, which has never been purple but a light tan.
I’m hopeful to see what progresses.
