I decided to check my water temp today before work and the digital display said eee. Like most I panicked checked the water and it was cold. Fortunately I had another digital display gauge for the heater, so I plugged that in to find the temperature at 34!! Now I've got the current heater working again, but I don't want this to happen again, so I wanted a recommendation of a really good heater for 60 gal. cube reef tank.
Thanks!
Thanks!
