John's 200-gallon mixed reef, known as MidnightReef, is a stunning and meticulously maintained peninsula tank in New York. It features a diverse coral collection, including SPS, LPS, and soft corals, supported by a complex lighting system of AI Hydras, Kessils, and ReefBrite XHOs. The tank's stability is achieved through a unique dosing regimen combining a calcium reactor, kalkwasser, and a doser, alongside an automatic daily water change system and robust filtration including mangroves in a refugium.

Husbandry

Protocols & Practices

  • Lighting scheme evolved from AI 32s to include ReefBrite XHO 50/50 strips and Kessil lights for intensity and shimmer.
  • Flow was initially challenging in the peninsula tank, starting with MP40s and Jebao pumps, then transitioning to MP60s for varied flow.
  • Uses AB+ to test water flow patterns in the tank.
  • Maintains a mixed reef, despite a perception of being SPS dominant, with a love for soft corals, torches, and elegance corals.
  • Rescued a nearly dead Acropora that regrew with two colors.
  • Has a burgundy coral that is three and a half years old, originating from a fish-only tank transition.
  • Has a Green Slimer Acropora that is about two years old and grows continuously.
  • Clownfish host in a leather coral and tend to stay in one corner.
  • Acquired clams from Clam Mania at Reefapalooza.
  • Utilizes a calcium reactor, kalkwasser, and a doser with AWC to maintain stable parameters and counteract pH fluctuations from the calcium reactor.
  • Feeds seaweed every morning and frozen food four times a week.
  • Maintains nitrates between 15-25 ppm, preferring no less than 10 ppm and no more than 30 ppm.
  • Aims for phosphates at 0.08 ppm or below.
  • Grows mangroves in the refugium for nutrient export, which are about four years old.
  • Uses a roller mat, filter sock, and additional floss for mechanical filtration.
