Well, your daughter getting hurt is not worth it, is it? Is the aquarium a DIY, or manufactured by a company. I know ours had a tag on the bottom glass that said it was an all galss aquarium. I agree with the eye sore statement - it just takes away from the beauty of the reef. And, I also thought that from my research on pumps that the sequence dart was pretty energy efficient (if you can call any pump that). You shouldn't need any power heads in the tank at all if you get the holes drilled so you get the flow you want. My opinion of course, and I'm relatively new to this, but so far our closed loop is giving great flow - without any wires in the tank...
