hi everyone!!! it's been years since i've had a reef because i've been moving around so much. i just moved into a house and plan on staying put so it's reef time for me. i have some work to do on the house before i start up but i want to figure out if an electrical upgrade will be necessary for what i plan on doing. i have a room which is 19' by 12'. i plan on having 2 6' tanks in an L shape along 2 walls. one will be a reef (180-210 gal.) with metal halides and everything else needed for a successful tank and the second will be a 210 gallon fish only tank. of course there is the possibility of the fish only turning into a second reef over time. the capacity of my service panel is 100 amp. i have a feeling this will need to be changed. what's everyones thoughts on this subject?
