My electrical outlets and everything I have plugged in in my fishroom makes me nervous . I only run one 15 watt light strip on one ten gallon and eight diaphragm air pumps are about 35 watts total , give or take 5 watts but eight heaters totaling 495 watts seems high . The heaters are not on all the time or all at once so it’s okay ( I tell myself ) . Now I’m adding two more air pumps and one more heater of 50 watts to total 545 watts . I have gang plugs and extension cords everywhere and they are good heavy duty ones but I still get a funny feeling looking at it . What do all the rest of you do ? Do you have nightmare electrical outlets too or do you have a method to control things ?
