Theresa_M Posted January 18, 2021 Share Posted January 18, 2021 I have a 75 long with a nice Eheim heater. I have the thermometer set up on the complete opposite side of the tank to monitor the temp. This is a newer tank - about 5 weeks now. The temp has maintained at what I've set the heater to. However, I have seen recommendations that two heaters for a tank of this size is ideal. Thoughts on that? Seems to be working fine as is, but would it increase the life span of the heated?? Link to comment Share on other sites More sharing options...
