I have a cobalt neotherm 75w currently heating my 13.5 gallon tank. When I set the temperature to 78 it keeps it at 76. When I set it at 80, it keeps it at 79.5. I would rather keep the temp at 78, but apparently this heater won't let me hit that range, it's either too hot or cold.
I've tried recalibration as best as I can tell and it still does this.
Every time I look for the best heater option the cobalts are topping the list and obviously it's not working for me. What's the best heater I could replace it with for this tank size?
Thanks!
