trying to decide if i need a dedicated circuit for my tank? the outlet near the tank that i was going to use(before i saw this thread..lol) has about 6 outlets/4 ceiling lights on it. it is a 15amp circuit with 12-2 wiring. the circuit runs in the den so there is the normal audio video load. tank is 120gallon with dc pumps and t5 lighting also running a chiller. am i over thinking it?
