I'm afraid its mono color and flat look would not work out. Thanks anyway.
They used to sell this rock printed liner but it appears to have been discontinued.
@Tai and I would also think that over time it would just get all covered w/green and you wouldn't see it unless you cleaned all the good stuff off of it all the time. The only part that would continue to show the rocks would be liner that is out of the water. Which would tho possible look kind of neat maybe.
