Hi,my tank (6 weeks hold) shows soe brown coloration at one side, more specifically the side looking at the window (indirect sunlight).

Some pictures of the coral substrate somewhere else (original color):

Picture of the window side of the tank with the brown coloration:

Is this normal? Is this coloration of the coral substrate or are these algae?

Fyi i bought this coral substrate:

It's not as beautiful as the original white but I don't mind if it is normal:). Or should I be worried? Shrimps are behaving normal, some are very red, some are pale. They don't swim a lot but sometimes they do and i see them frequently eating algae present in the tank..

Yup just another post relaying what @Algae In Space has said, very normal and is part of the cycling process. If you think your shrimp are happy now wait till its fully cycled (which wont be far away).

Get a few horned nerite snails for your tank, they will eat up the algae and wont breed.

Yes but they lay eggs everywhere don't they? I don't like that... And will they leave the water? My tank isn't closed on the top...
