Is the window screen something that can be attached to a fugeray instead of covering the tank?
Yes, supposedly there is no difference. By some weird chance I happened to have a window screen in a wood frame that almost perfectly fits the top of my tank so I just set it on the tank (it leaves a few inches of space between the top of the water and the screen). But I've been considering growing emersed plants, so I'm pondering how I can put the screen at the light. I have a plexiglass piece that covers the lights so I've been considering putting the screen along with the plexiglass.
