Hi Kimchi I believe you have the same problem I encounter once in a while. It's basically bacterial colony or fungus, its definitely not algae. did you do something to your filter or water? just let the water settle it will go away. also cut down your leftover food and do 10% water change 2 times a week if your tank is matured already (your tank looks matured). if new tank then 10% a week.
