Nativevaman from this forum helped me pick out my lighting setup. Everything has gone great from his advice. Bulbs may be about 6 inches above the water surface, but I will have to verify this. Only time water quality goes down at all is when I feed DTs or Coral Frenzy at night an turn the skimmer off.
