I did a water change and gravel clean this past week but my aquarium water is super cloudy and the corners and filled with the brown dirty water. I don’t know what’s going on or what I need to do. Here are pictures
The brown if it is on things and not the water its self it would be diatoms (I am guessing this is a new setup) They feed on silicate from the glass and will go away on their own. Nerite snails will eat it.
