New tank setup

[marine newbie]

I hope someone can answer some questions for me. :confused: I got some of the caribsea sugar sand and put it in the tank after i filled up my tank with seawater however the water is now a tan/brown color and has been like this for 2 days now :( , is this normal or did i screw up.
