it'll be fine, but you're certainly not going to have to worry about the light getting to the corals, more just nutrient control and salnity control, since you've got a tiny water volume. The evaporation rate and conecncration of nutrients rate in a tank that small is what are going to be your difficulties, not getting enough light over your corals.

Ya everyone sais about evaporation, but if all I have to do is add a small amount of water out of a jug everyday that's no problem. What's annoying is lugging 5 gallon jugs up to my 75 to fill it up that's annoying!

You'll be fine. I ran a 10g with a 70W MH that was loaded with SPS.
As others said, keeping your parameters inline & evaporation will be a bigger issue. I'd definitely invest in an ATO if it were me.

yep, plenty of light. I would look into some sort of ATO to deal w/ evap. I would at least look into the salinity swing in a day by testing before your top off. I generally find a few times a day is better than once a day.
