These are for the new 20 long I'm going to set up for Cardinal Tetras, but thought I'd put them on the 20 long I have going now. I never liked the hinge on the glass tops. It blocks light to the front and doesn't allow me to put the light exactly where I want it. This top is 2 custom cut pieces I had made at a glass shop. Only disadvantage is having to remove front piece and set to the side while feeding. I like the Aqueon LEDs. This is my first LED
setup. And the blue night lights are really cool. Only thing I don't like about it is the LED
strip doesn't go all the way across and doesn't put as much light in the ends of the tank.
