i really only want plants so it looks abit better....not for filtering,its about 600mm deep with washed river stones in the bottom,with about 20 small koi,well and budget $40.000 was spent on building a back room for the pond.
You should be able to find them cheaper and with a reflector, this waas just for reference.
Hang it from the ceiling or make a PVC / wood stand for it and hang it about 24" from the water (adjust height to your liking just so the plants get enough light).
