hi,
My mum's boyfriend has one on his pond and it looks fantastic in the dark. His one has got lights built into it so the whole mist seems to have strange a glow to it, it looks realy amazing. He also some lights emdedded into the brick work around the edge of the pond just above the waterline, when these are switched on and the mist rolls across the pond it is really nice to watch. HIs pond is full of Koi and it doesnt seem to bother them.
