The heater I had was a cheap odyessea (sp?) I will look into a better model for the next one. Any recommendations?
I originally had a floating thermometer, took it out fearing the aro which has quickly grown to ~12" might try to eat it. Went without for awhile and picked up a digital one with a small probe in my overflow, that's when I noticed the heater was not working.
I do not believe my fish are in immediate grave danger as all are active, feeding, growing like crazy and showing great color. Just thinking maybe these fish can thrive in wider temperature ranges than most people think.
As far as the cost to run a 300w heater, at 15cents/ kwh it could cost hundreds a year if that element is energized for more than half the day. Nothing wrong with trying to save money imo IF it won't harm the fish.
