This is my sand substrate tank.
The plants are Vallisneria (right), Hydrilla, and an Amazon sword now growing in a semi floating log , moved to the log because the Valisneria were choking it out
I don't use ferts, or CO2.

Hydrilla left side below, water lily stems toward the tight side

lily pads floating

The tank is a 180 gal, that gets about 3 hours fairly strong, eastern sun in the morning, and maybe 2 hours indirect less intense, western sun in the late afternoon.
I don't use any artificial light. It holds about 15 fish most are cichlids

in the 3-5" range, (and one 10" goby)
