So, some people wanted to know about noise, and after I took this video (which was for the strict intent of hearing the waterfall), I realized that I do not have a professional camera. You hear the background noise that you get when you cup your hand to your ear.....that loud consistent noise is NOT there. The pumps are all outside and there is no AC on....

But, you CAN hear the waterfall and the crabs "clicking" noises so I thought I would post anyways...

Hope you enjoy it....very nice to relax to. This is exactly what I stare at for hours a day!
