This seems unusual. Would you please explain the reasoning for the design of the sand bed this way?
Thx,

The sand bed closed to glass is keep in empty, maybe we will try Garden Eel in this area, so the sband bed is more deep

Are those black things on the sand huge worms? Eels?
Thanks, now we have four 400W metal halide (XM 10000K) as supplement, sunshine in Beijing in winter is not powerfull enough , but we do not know how about it in summer.
The entire house is build with the pool, the location and direction is design to maximize the usage of sunshine, so I think reflectors could not help much for this setup.
