just go with flourecent lighting. It is cheap, easy to run and cheap on electricity. I have 3 lengths of my tank and I keep LPS and SPS. Everyone says it should not work but it does! You don't need all this fancy MH stuff unless your either really hard core or you have alot of money. Just keep the more sensitive stuff near the top. It is the best to buy the flourecent holders are everything at hardware stores and just buy the real aquarium light sticks.
