HELP my tank is getting progressively more cloudy and corals aren't looking good

Pic 2 if from a week ago and pic 1 is today. My phosphates and nitrates have bottomed despite my efforts to rase them with reef roids and heavier feeding. The tank is over 6 months old and I only have 2 clowns. The tank is getting cloudier daily and I'm not sure what to do so eany advice is welcomed
