Re: [GSAS-Member] Do heaters die of old age?

Hi Matt,

Based on what I can find, if both heaters are working properly and the tank
has good circulation you should not have a problem.  I think Shango may have
hit on one possibility; one of the 250 watt heaters has failed or is turned
down too low.  If only one heater is working on that 90 gallon, heating
capacity would be undersized for your tank and during a cool night the
aquarium temperature would drop.   If the heaters have indicators, do both
light?  If so, do both heating elements get warm?  (Obviously check with the
heaters in water!!  LOL)
