Dear Sir or Madam: <"Will you read my book..."> I am acquiring a large amount of live rock for a new 75-gallon reef aquarium with a 29-gallon refugium in the cabinet underneath. The live rock is coming from another metal-halide illuminated aquarium populated with corals and anemones. I plan to “cycle” the live rock for a period before introducing new organisms. I plan to divide the live rock into two categories. The live rocks with anemones and corals will be placed in my main tank to enjoy 300-watts of DE-HQI-MH lighting. The main tank will also have a deep sand bed of oolitic aragonite that I will “seed” with SeaChem Stability. The live rocks that have no anemones and corals will be sharing a bare-bottom refugium with a hang-on-tank skimmer, a cooling fan, a heater and an external pump but no lighting at all.
