This tank embodies the BRS/WWC Hybrid Method, focusing on long-term stability for SPS corals. It features a bare-bottom design with high flow, extensive mechanical filtration, and a prolonged cycling period. The system prioritizes simple and stable chemistry management, relying on weekly water changes and a calcium reactor, while incorporating utilitarian fish for tank maintenance.

Husbandry

Protocols & Practices

  • Utilizes a bare-bottom tank with high flow to keep detritus suspended for mechanical removal.
  • Employs a 4-month cycle for new tanks, adding fish and allowing stabilization before corals.
  • Changes filter socks or pads twice weekly, or uses a roller mat for less frequent media changes.
  • Runs carbon in a reactor to remove yellowing, odors, and organic toxins.
  • Maintains target parameters of 8.6 dKH alkalinity, 480 ppm calcium, and 1440 ppm magnesium.
  • Focuses on utilitarian fish (e.g., tangs, wrasses, blennies) for algae and pest control.
  • Cleans pumps when they look dirty, not just when they stop working.
