Getting ready to set up my 90 gallon shortly. Need a bigger heater. I'm looking for something that will heat the 90 and sump but not be 500 watts. I live in an apartment and only have one outlet close to the tank so I don't want to overload it and have the breaker tripping constantly. I saw an eheim on Amazon that's 200 watts that's ok for up to 110 gallons. Any advice would be helpful. Thanks.
