Yesterday's poll looked at preferred macro algae and chaeto was the overwhelming preference of those that participated. In second place, albeit a distant second place, was Caulerpa. The one negative thing I've always read about Caulerpa was the potential for sporulation (going sexual) and how invasive it can become - both in the refugium and in the display if it makes its way there. So I'm curious if those that have used/tried Caulerpa have had an experience with Sporulation. If so, which species was it? Share your story for those considering using the macro algae as part of their nutrient control.
