Upgraded - Help needed

[MarineDan]

Hi all,

I recently upgraded from a 64L tank to a 125L tank and moved everything over including my live sand.
I've done a few water changes, brought Marine LED's ( Arcadia Stretch ) added a few bits of live rock, ordered a skimmer ( waiting for delivery ) added a Red Sea starfish, Giant Turbo Snail and a Cleaner Shrimp!
I tested my water yesterday before buying these and everything was spot on, although my Nitrate was 0.5 which is no biggy.
Today I've woken up and noticed my sand bed is almost covered in brown like algae which is also growing up the glass.
Is this normal and nothing to worry about?
Pictures for reference.

I want to say mini cycle. Since you moved ur sand too. I would say that may be causing your diatom issue. I would not worry too much. Did you add more sand and rock?

Hi Thanks for the reply. At the time of the move I didn't add more rock they came yesterday and the day before that. Only sand in there is from my other tank.
