This 5 layer stacked polished rock makes a perfect pyrimid effect for water flowing over the rock.  The fire is ignited right on top of the water and includes the burner.  Electronic igniton is available as well but a thermocoupler sticks above the water and can get spendy.  We recommend these be hooked directly to your house NG line but could run off a tank if need be.  Email us for more pictures and videos, and more selections
