Ceramic basin I think I found at a garden store... antique hand water pump at a garage sale or junk shop - can't remember. Pump is super cheap fountain pump like at home depot. Abalone shells have been collected from the beach over the years. Whole thing is maybe a foot and a half around. Can't remember why I put it up on the Cedar blocks - statuary is garden store clay something or another...
I've had this basin and other parts in a variety of configurations over the years - this is just the current one. Water is blue from a splash of cool mist fluid to keep the iron pump from rusting. I drop a bromine spa pellet in to keep algae away. It runs an little more than a trickle, so not really a sound mask, per se...
