Reefkeeping: Old School vs. New School
Here is an "old school" soft coral aquascape featuring earth-tone brown color palette and full spectrum lights. This type of aquarium ruled the scene in the late 80s to early 90s.
And here is a "new school" stoney-dominated aquascape featuring brilliantly pastel "ultra-low-nutrient-system" coloration and blue lights. This type of exhibit dominates our hobby today.
