Could I have ruined my heater?
I have a Aqueon 50w heater in my tank, Evolve 4. I have the heater in the pump chamber.
I was doing a 1gal water change, and forgot the pump area will become empty immediately. So I quickly put the water back in the pump area.
Did I just ruin my heater? I know it says to keep it submerged the whole time, otherwise unplug.
