This is the 215 gallon Acropora dominated reef aquarium which I set up and maintain. This aquarium is using 2 full sized vortech pumps, H&S skimmer and reactor, 4 x 250W DE Phoenix 14k halides, 150 lb tonga rock, Aragonite Reactor Media for the substrate and it it about 4 months old. It replaced a 2 yr old 220 and 90% of the corals were grown from frags or aquacultured colonies.
