Aquarium Advice Apprentice
I'm looking for a new heater for my 75gal. I'm leaning towards 2-200 watt heater cause my tank is fairly long (4ft). I'm looking for opinions on brands like Viaaqua, Odyssea and Weipro.
Good point, I didn't look at it that way. I prefer to have the ability to support the tank temp on one heater if the other the should fail. I have both of my 400's powered through an aux relay that is being controlled via a electronic thermostat that I added circuitry too, and is set to kill power to the heaters should the temp get above 84. I'm worried because my tank is in the basement and it does get quite cold down there in the winter.Redundancy isn't really what you're after. One of the schools of thought for using 2x heaters is that you size each of the heaters for 1/2 the load, so that combined, you have the wattage you need. That way, if one of them sticks in the 'on' position, it takes longer for your tank to get to "death zone" temperatures. That extra time gives you a longer time period to possibly find the problem and react before it becomes a serious problem. Same thing goes if it sticks in the "off" position - you at least have *some* heat going into the tank and the temps won't drop as fast.
