Nothing grows!


My 13 year old reef tank is fine, but not awesome. While my corals don’t really die, they also don’t grow. AT ALL. Same with my macroalgae in my fuge. I’ve got stable parameters, excellent equipment— nothing grows. Any advice?

A lot of factors at play. Perhaps a list of those stable parameters, your dosing and maintenance regimen, your hardware, and your stock list would reveal something. It could be low nutrients, high nutrients, a missing trace element (i.e iron), insufficent light (starving), excess light (photo inhibition), the list goes on.
