I hide the false bottom of my tanks by filling in the gap with gravel. Let me explain, when I cut the egg crate I make it 1/2" too narrow leaving a space in the front of the tank. I wrap my screen under the spacers and then around the front of the eggcrate. Fill the gap with gravel. Just make sure you secure the screen so you don't get a blow out allowing the gravel to slip under the eggcrate.
