Milky cloudyness

[Aqua_Matt]

Hi I have a well established 100litre freshwater tank, with sand substrate & mostly artificial plants. It’s currently quite under stocked. Up until recently my water look lovely crystal clear, but over the last week has got a slight cloudy-ness/milky colour. Not that obviously from photo? Water parameters all still testing good 0/0/5ppm. Any ideas would be gratefully received???

Milky cloudy water is caused by uneaten food and a filter that isn't established.

Reduce feeding and do a 75% water change and gravel clean the substrate every day until it clears up. Make sure any new water is free of chlorine/ chloramine before it's added to the tank.

Don't clean the filter for a month and don't replace filter media/ materials.

Thanks for the advice ?
