Can the EHEIM Jager 50 Watt be placed horizontally?
I have a 10 gallon, but this heater already seems way too tall. The water is evaporated so I need to do a water change soon. I’m just keeping the heater in there before I turn it on before I plug in my old one
Can it be placed horizontally or it must be vertical?
I believe you can. I don't use eheim, I don't see the problem of placing it horizontally.
