how far above tank for lights?
The problem isn't always with light escaping the hood when it's far above
the tank. A lot of light is lost because of the angle that it hits the
water, it simply reflects off the surface and get's bounced around in the
hood until it either escapes or gets absorbed. When you raise the height
of
light source the ang ecome less favourable for entering the water. So
even if you've got a perfectl losed hood, it's still best to have the
bulbs as close to the water as possible, unless of course your hood is
covered with mirrors inside.
