EheimThermocontrol e250 Heater, Black (AEH3638090)

I use the e250 in my 40 gallon Reef cube. I have a Neptune Apex that can control the on/off temp, but that isn't necessary. I set the e250 for 79 degrees on the manual dial and my temp stays 78.7 to 79.1.That is the most accurate heater I have owned and the most consistent in very close temp control. A second to none heater!You may see a very slight amount of condensation in the bottom or middle of these heaters. It isn't leaking, it is the sealant Eheim uses when putting the heater together.I've use every titanium heater you can use and they've all went bad very quickly and tripped my GFCI outlet. After this E250, I have never had another problem with GCFI issues.

I have been using Eheim heaters for years and have yet to see one burn out or fail so when I upgraded my 20 long it was a Eheim to the rescue .It is extremely accurate and easy to set up , dial in your temp , and forget itIt has 2 led lights , one lets you know when power is on , the other when it is in heating mode , nice ! :)

Desastrozo!!!!
