do I need a bottom drain?

Ok, I'm nearing the first stages of pondhood... the digging. As soon as I
can get my sister-in-law's electrician husband to put in my outdor GFI
outlet digging will commence. Once that's done I'll get the liner, the
pump
etc for the waterfall, the edging rocks. I have a few questions:

1) Does remnant carpet or carpet padding work ok for cushioning the
liner?

2) Can I put old carpet for cushion on the bottom too or is that only for
the sides and I must use sand on the bottom?

I was going to use carpet under mine, but when I had to fight my utility
knife to cut through the EPDM, I said screw the underlayment. If I have to
work to cut it, there ain't no root that will be stopped by carpeting.
