Nano tank question

[x0xvi3t]

I just set up a 10gallon tank with coral and pair of clown, ai led, heater, filter, skimmer, also wave pump. My question was why there a lot of red stuff build into the rock and the glass, What are those and what should I do? Do they harm my fish and coral?

Thank you cloak that exactly what it is diatoms, thank everyone for the help I just don't get why is keep coming back when you wipe it off.

Be prepared for up,to 6 months worth of strange growths and an overall ugly and dirty looking tank. Don't fight it. It's normal.......

You think is a good idea if I bring down the light make it less stronger?

Diatoms are the food for your snails, pods, and other cool marine critters. You just have to keep cleaning up where the snails and stuff don't get it all. Part of the reef.
