I had something like that where I placed the carbon bag directly in my drain and the flow was too strong and the carbon kinda disintegrated! It Caused my tank to look very clowdy... I did this because like you, I had no skimmer for 2-3 days. When I placed the new skimmer in, it started to pull out all the carbon dust and another thing it help a lot was to place a filter sock right under the drain....! Good luck!
