Great point and link, Diana!
If conventional wisdom were never challenged, then there would never be innovation (or variety)!
I think applying research and critical thinking vs following a recipe are behaviors we all employ with our reefs, and that's what makes this hobby interesting! Otherwise it would be akin to baking... add a tablespoon of liverock, a pinch of refugium, and a healthy portion of protein skimmer... mix, put in tank, and it will come out just like the picture! Ha right!
