I have a Fluval M300 300 watt heater in my 75 gallon. FX6, ambient room temp is 69. Heater is set to 82. Fluval says the M300 is good for up to 80 gallons.
The heater turns on for about 20 seconds, then turns off for about 2 minutes. And repeats this all day. I work in the room the tank is on and hear the audible click every time it cycles on/off.
I read posts where other heaters turn on/off 10 times a day, not 20 times an hour.
Is this normal? Why such short cycles?
