I bought a new eheim jager 150w heater for my 40g and it been on for 3 days now and my tank won't exceed 68f. It claims it's good for a tank up to 75g. The room my aquarium is in is around 65f.
Any ideas ?
Thanks !

The red light hasn't shut off and I left it on max setting the whole night and it still hasn't went over 68First off, welcome to R2R.
Is the little red light still on? Are you simply relying on the temperature set point on the ring? If so, you first need to calibrate the heater....that outer ring rotates to calibrate the heater to the actual temperature.
