Hello everyone. I'm new here but have a few questions off the bat. I have been building ponds/waterfalls for a while now and I have a client whom would like a waterfall for his pool. Now i've done a bunch of surfing to try and figure out how to go about this and have not really found anything helpfull. I hope you can help me. Anything would help. I've seen preformed acrylic or fiberglass moulds, real rock installs I'd like to know what i'm getting myself into before I say yes. Please just send anything you can my way. It would really be appreciated.
