Have anyone tested the best location to place the heater for maximum heating and low electric power consumption? I have a Red Sea 350, and I place my heater in the main sump area, and I'm using a Eheim Jager 200 watt heater. During winter time I have to turn up my heater to the max, and the temperature fluctuates between 73-78 depending on the ambient temperature -- I do have a temperature sensor to shut off the heater if temperature hits 79 degrees. When ambient temperature is low, the heater kicks in and can consume quite a bit of electricity, and the electric bill can go up quite a bit. Let me know if you know of a best place to position your heater for maximum heating and low power consumption, cause I'm trying to saving some money on the electricity bill. Thanks!
