I currently have 2 25W lights in the cover of my 10G tank. To help the lighting process i have considered removing the little plasitc screens that partially block the light coming from the lights. I was wondering if these little covers are essential for the health of my plants, or more importantly my plants, or if i would be fine without them on there at all. If i were to take them off would it actually help my plants receive more light because less would be blocked, primarily none at all.
