No, the high FC (which is what makes the TC high) should not cause cloudiness (at least not by itself -- chlorine can raise pH and that combined with high CH and TA can cause cloudiness, but that's not your situation). I suspect it's just clearing up the last of the algae or other organics that have been in the pool. Just keep circulation running and keep the FC high until it's clear, then let the FC drop, then adjust the pH (if needed) and have fun in your pool!
