Review on 🔥 Ehm Heater Jager 300w: Powerful and Efficient Heating Solution by Monique Lopez

Received in excellent condition as expected. It maintains the ideal temperature of 78.5 degrees in my 55 gallon fresh water tank. I thought I had enough room to mount this heater vertically in my tank, but I didn't. My tank is just under 24 inches, but even with the heater end down to the gravel dug glass bottom, it barely made it past the minimum water level gauge. So, contrary to the instructions below, I installed it horizontally in the back and center of my tank. I believe the reason the MFR only recommends vertical installation is because of how it controls temperature. The heater kept my tank much warmer than when I installed it when I originally installed it. I calibrated it after 24 hours and now it keeps the ideal temperature. It doesn't need to be running in my tank very often or for very long. I have thermometers on each end of my tank and they both read the same and the same temperature. It never fluctuates above 78.4-78.6. So, while I haven't followed all of the instructions fully, this heater has worked great for me so far. It works exponentially better than the cheap 200w heater that came with my tank kit. the temperature would drop by two degrees if it were cold. This heater keeps the temperature right where you set it.
