I am new to Aquariums as a whole and and am currently experimenting with Freshwater tank.

The above attached photos (3) show the coloration of the sand in my Fresh water tank.
The deposits are not even on the sand since I disturbed them to mix the sand.
Can anyone at a glance tell me reason for such deep discoloration and how I can avoid it?
