I am interested in a waterfall for our 18 x 36 Liner pool. My wife really enjoys the noise of a waterfall. I have been looking around and came across this from Pool rock.com. I was wondering if anyone on here has purchased a waterfall from this company and how realistic it actually looks. PB said he could build us a natural waterfall as well so that is an option. But we are on a budget here so I am leaning toward this. Just wanted some opinions.
