Welcome to our forum.
I rarely use the waterfall. If I have pump one on low speed it adds a nice touch, but with both pumps on full you can't really hear it over the jets.Good luck.
looking at SD Optima and Artesian Emerald. I was first sold on the water falls on any spa,but now might have a change of heart. My guess is that most when sitting in the tub have the jets on. Would you really hear the waterfall then?? For those of you that do have one do you use it much??? As far as filters, The artesian guy told me that the SD has the filter sitting sideways and the water flows right over the top. The artesian has the filters sitting up and down and has two of them. I still don't think I'm sold on the SD "no-clean"filter. Opinions from all of you please. Secondly, When I looked at the Piper glen I just loved all the lights. The Emerald only has one light. Just does only one light light uo the whole spa in the dark for that unique glow?? Personally i love the piper Glen, but my wife said we don't need anything that fancy. So opinions on the lighting too, please I probly ask the dumbest questions on here so forgive me. If it was the Sundance Optima or the Artesian Emerald, What would you buy?
My Jaccuzzi (J345) has one light, when I bought the tub I didn't get the LED option.
The aftermarket light is great and well worth the money.
