i want to add depth to the substrate in my parahybana tank, she's in a ten gall and the sub is only 2" i know it needs to be a lot deeper. but i don't want to spend 20$ on coco fiber to fill it up..so will it work to use some dirt from my backyard to fill it about halfway up and then put the coco fiber on top of that? does anyone else do this?
