well i got a 55 gallon today and my old 20 is in the corner away from my window.the plugs by it are not grounded. i can put the new 55 by my window where the plugs are grounded..but could it get too hot? the windows have thin sheets and blankets over it too block out the sun..cuz im a vampire.
do the plugs need to be grounded? i have two lights a heater and a filter...all not grounded..will it matter?
