I actually reset mine up....the same way. I wanted a little more water, plus the base layer wasn't deep enough or level enough. So, I added more and cut a new screen divider. I got a huge roll for $5 at home depot. It's the same screen that came with my kit. I took a pic to show you how the water line doesn't touch the soil. I guess your way is fine too? I'm just goin' by what I read on blackjungle.com I like the gravel look better, but the say the terralite or hydroton allows better drainage. Did you use a screen divider? That keeps the soil from creepin' down and cloggin' up the gravel...
