Zinnib,
Thoroughly wash your gravel and place some in a large cup or measuring cup. Then lower the cupful of gravel to just above your gravel. Then slowly pour the gravel out. After you get your gravel in, you can then smooth it out. This will minimize the amount of cloudiness you will have over just pouring it in from the top. Hope this helps. You'll still have a little cloudiness but your filter should take care of it in a few hours.
Good luck, OS.
