I recently just installed an aqueon submersible heater into my new tank and a few hours later i saw condensation inside the glass. Is this normal for a submersible heater to have water inside it? cause the light is still on and its still warming up the tank. its just there is a bit of water inside it.
also if i need to return the heater what other heaters could i buy that is a lot safer than the one i have? any suggestions?
here is a picture of the heater.
