Hello; Let me check if this is the situation. You started two tanks at or about the same time. One is clear and the other is cloudy. The two tanks have different décor being the main difference. If all this is correct my first thoughts are that the décor is somehow the issue.
My second thought is the drift wood or plastic might be shedding something.
However I do like the already mentioned suggestions better than my own. I would give it a few more days with perhaps the lights off more hours.
