I have observed that in the past week some sort of brown spots are appearing on my sand bed and a bit on some rocks, not sure if this will become some sort of algae outbreak ? My tank has been running for a month with fish I used dry rock and cycled with bacteria.
What is this? Should I worry

It will normally go away on its own as long as there isn't a source of free silicates.
Using tap water can keep it from going away. Otherwise, it is very rare for it to last more than a few weeks.
