this is my list so far
light = 129 (hellolights.com)
2 powerheads = 37 (cheap from aquariumplants.com)
salt, high pH kit, aragonite sand, hydrometer, 10 gallons of R/O water-$74 (LFS)
This is with out live rock or any livestock. Live rock is gonna cost at least another 50-60 bucks if not more. Also I already had a heater, thermometer, tank, stand and nitrogen test kits.
