What color is the cloudiness? If you added red clay to the soil, and the cloud has a pinkish tinge to it, than thats clay. That should go away, as I've had the same problem with my dirted tank (though I used gravel). It vanished after 3-4 days with the filter on and partial, minor (10-15%) water changes, not major ones.
The tea-like discoloring could have come from the wood or soil. Both release tannins which the carbon in the filter will help to clear up.
