Yeah, my secret to what my fellow local club members suggest is a wicked looking tank is based on a few things besides just lighting. I have alot of water turnover... 60-90x is my goal usually. A calcium reactor is beyond what I could do with manual dosing or just a kalk reactor. I run carbon, and a very effective skimmer. From time to time, I will even dose ethanol to 'strip' my water of nutrients, although as the tank matures, this is less and less necessary. It was more to get the tank through the initial cycling, but once past that 6-9 month period, the tank balances out and nutrients usually arent as much a problem. Then I start dosing potassium, iron, iodine, etc. (Oh, and rather than fancy Fauna Marin Ultra Organic for $40 a little-bottle, get KENT Essential Elements or Coral Accel... its the same thing for 1/4 the price). I am considering an Ultralith/Zeovit setup... not sure yet. But yeah, there is alot more than just lighting going on.
