Is my heater broken

[Roman'sReef]

my eihem heaters havent had the orange light indicating there on in what seems to be several days but maybe ive just been at school and havent been there to see them on and the water seems so cold but here

Thats around 81F... pretty warm for a reef tank. No tank should ever feel like a nice warm bath to us

Now for the heater idk maybe your ambient temp around the tank is keeping it that hot

27,8 is high. That’s not cold at all. Get an inkbird controller if you want to make sure your heaters are working fine.
