Getting closer to a reef tank at work

[Ippyroy]

The owners of the hotel I work at are getting closer to accepting a reef tank. I am getting stoked about it. It will be either a 120 or 125 gallon. I live in an older cabin and keeping my PH up is not an issue. In a hotel with over 300 people in it every night will be a different story. Other than PH, is their anything else I would need to look into? I am going to use a canopy for obvious reasons.
