lighting recommendations
I have about a 70 gallon aquarium. dimensions are 48 long x 21 wide x17 high. I am gonna go with metal hallide i believe. probably 250W 20k. Would i just need one or would I need more. If you think 175's would work better let me know. I am starting with just FOWLR but will soon be getting into corals and eventually SPS. I would like to buy the proper lighting to start so i don't have to uprgrade. Do i need any special light for the live rock to start with? Thanks guys
