Humidity problems for large tank

[ClubReef]

The tank will be a room divider with 3 viewable sides so I won't have a dedicated room...a sink won't be installed either (my wife already told me no . I will have to use the sink in the washroom or the utility room.

I'll look into the hotwater line though...I might as well since the walls are bare and I might have a dedicated sink or wet bar built close to it in the future .

Do you think 3 circuits will handle all of the power requirements? I don't want to get too overboard because at the end of the day everything will add up (they charge $130 for each circuit). 3 circuits will be 45A of power. I can see my biggest power draw will be from the MH (3 X4.5A) +Chiller (9A) ~21A
