I mixed cork, cypress wood, and foam covered by coco bedding. It seems to be working out great. Next time i would make sure i control the drip wall better though. The water seems to have a mind of its own.
1. I layed the tank on its back do you are not fighting the foam/gravity.
2. Arranged my wood pieces
3. Filled the gaps with the foam. Be warned this stuff expands a few inches and is very flammable.
4. Added a few more pieces of wood and cork bark after the original foam was fairly solid, about 3 hours.
5. Filled in the gaps
6. Repeat until your happy.
7. Working in small areas, apply silicone and coco bedding or similar material over this.
8. Once its dry remove excess material.
I also siliconed the entire back and enough of the sides and front to hide the false bottom and foam. This gives it a nice finished look. Of course my tank is in the living room and not on a rack like most here.
Thats how i did it. Let me know what you do different.
No, i get most of it from around my house(realy good stuff) got my frogs from pet Bizzar in castleberry, and going to the tampa show tommorow to pic up stuff. I love miami its so awesome down there. I go every now and then its so much fun.
I used the foam to fill in behind the cork bark and the cracks in between the pieces, and that in turn held everything in place. I didn't want my frogs to be able to get in behind the background. After it dried I just carved away the excess and smoothed it out with a Dremel, then used the 100% silicone to attach the coco mix to cover any foam that showed. It is really easy to work with.
