Heater Advice Please

[Waffen06]

So I dont know what I was thinking but bought a 150w eheim heater in the spring for my last tank. Moved it to my reefer 250 a couple months ago and it kept it a nice 80 degrees. Well in ohio we had a quick drop in temp down to the 40s at night and only a high of 61 today. Not enough to kick the furnace up yet but realized my tank has dropped to 77.4 degrees. House was kept at 76 in the summer so it didn't have a problem keeping it at 80, now the house is around 70 and it cant keep up. Should I upgrade to a larger heater or get a second 150 eheim? Was looking at getting an inkbird controller as well.

I would get a second heater. This way if you have a heater get stuck on, you lessen the chance of turning your reef into 250g gumbo.

I would get a second heater. And definitely get a controller, like inkbird or even better, ranco.

Redundancy is good and seperate controllers and temp probes! And I would get a titanium heater.
