couldnt give you a exact price but i would say its at least $1500 tank was $250 then lights were $450 then theres all the other stuff like pump, wave maker, sand, salt, corals, live rock, filter media, cuc and so on but a little birdy has told me there are soon to be some awesome all in one nanos comming out specificly for salt water with good quality gear that should not need to be upgraded and they wont be too badly priced (not made by a big name company but combining the best gear from the big name companys to create a awesome all in one package)
