Issues with the electric service here. Had to revamp the way I am doing this. I ordered a vent free heater to heat the basement instead of heaters in the sumps. Thing is they are in one of my breeder tanks that I don't run off the system. Lack of tank space. Since the individual heaters in the breeder tanks overloaded the system and keep tripping breakers I had to put heaters in the most important tanks and hope for the best with the others until the vent free heater gets here. I will be relying on ambient room temp to heat the tanks instead. That will eliminate the need for any heaters.
