Hey John, this is cool! I've been wondering about how to get a false/draining bottom to co-incide with a pond without silicone-ing anything permanently in place. I didn't want to have to scrape it all out again if I decided to change it in the future. I posted a thread but alas no-one answered it. I guess looking around pays off. Figures that I'd find it in the most obvious place lol. I think the Dart frog part at the beginning of the title lead me to believe it wouldn't be so versatile. I was wrong YAY! Now all I have to do is find a long enough piece of bark that can withstand water.........
