I have that $100 pump/filter combo from Lowes and it came with a nozzle head that sprays water up in 3 levels....it doesn't look it in this picture but it's actually quite high. I don't like that though, it makes my plants wet, so I'll be getting a bubbler one soon that just sort of bubbles out without splashing too much. I mean I love the way it looks, but it's not practical if you have pond plants. When I bought that set the man told me there were lots of interchangeable fountain heads.
BTW, the pond isn't THAT green, I had the camera on foliage setting and it makes things seem greener than they are.
New mulch makes a big difference!
BTW, do you already have a filter in your pond? You just want a pump or a pump/filter combo?
