Is there such a thing as too much lighting?
I already have 175w PC 50/50 on my 40 and from what I've read I can only have "the basics" as far as coral.
If I got a 175w MH, do I still keep the other lights or is that too much?

When looking to lighting...the amount and quality of light penetrating the depth of your tank is what you guide by. I do not know the measurements for a 40gallon...but my 45 is 24 inches higher and I opted for the 250w MH.
