If you've read my posts, you know that all of my displays are macroalgae dominant, with little to no coral. I recently was told by some hobbyists that macroalgae does not belong in a display, especially caulerpa, and only should be in a sump or refugium. That also makes me realize that I know very few people online that actually have macroalgae in their display tanks. I assume many of you also keep your macros in a fuge, but why exactly? I want to read your standpoints. What experiences do you have with macro in your display? Good? Bad? My clownfish seem to love the softness and smoothness of my caulerpa, my clown gobys like perching on my textured, firm gracilarias, and macroalgae will keep nitrates low, make homes for my copepods, and are visually appealing. so I would imagine they're a positive contribution to a saltwater aquarium.
