I use pool sand. I too thought about putting a layer on top of my gravel but Kristin talked me out of it. Through time it will seep through into the gravel and you'll end up with a mess.

I changed to sand to prevent my Cories from injuring their barbs and I'm glad I did. It looks a lot better, and most of my plants will stay in it without floating. I was even able to get my Java Fern roots to stay in without having to tie them down to anything.

I haven't had my plants long enough to say how well they are growing but they are looking great.
