Their plastic screen is just fine. Realize you will loose a fair amount of light through the screen. I actually used screening as part of my light acclimation when going to LEDs.
Is it pretty much the same as what you get in a kit? I have a glass top but I'm trying not to loose light. Whats a common screen used to keep small fish in?
I thought you were talking about conventional screen you find on a storm door. The bird netting mentined above is much more open than convention screen and therefore will allow more light. The BRS screen (FOUND HERE), comes clear and is available in ¼ inch and ½ inch sizes.
