first thing in a morning, my water is crystal clear. then about 10am, it starts to go cloudy & by afternoon its really cloudy. It stays cloudy till about 7pm, then starts to clear up & by about 9pm its crystal and stays cyrstal till about 10am the next day and starts all over again.

i dont know whats making it do this ??? im fully cycled, my water stats are fine & im not overstocked. were my tank was placed meant a little bit of sunlight would shine on it through the day and i thought that may be causing it, so i moved it but its still doing it. any sugestions ???
