Thanks. I can't fill it up anymore because the other side has a leak. That's why I divided it half land. I made it just for a cool vivarium, not to keep a turtle in. I wasn't planning on adopting a turtle when I set it up, that's why the water isn't deeper. I was in the process of making this turtle an escape proof outdoor enclosure. I just started on it and now something is wrong with the turtle and I can't find her. I've really looked through that dirt. I will have to empty the whole tank tomorrow when I have the time.
