<I cut a flower pot in half, and I cut a small hole at the top.> Congratiulations ! I always get several pieces :-) For a more natural approach, try one of the Coconut Shell's. Maybe even more fun then the flower pot ! :-) The coconut shells will also release over time a certain amount of beneficial humic acids. Sand is a lot of fun too. But I am affraid it will not work in your set up. The Sand will always sink to the bottom and push up the gravel.
