CA-Delta;4839651; said:I don't think there is a minimum or even optimum size when you are talking about heaters. It has more to do with ambient air temp and desired tank temp. For example I have a 240 gallon tank in my living room. The room temp is 68-72f and the tank temp is 78f. This is achieved with a single 250 watt Ebo Jager.
