I did a search and couldn't find an answer to my question.

I have an ASM G3 skimmer. Currently there are no fish in my tank so the bioload is probably very light. My tank is 120gal with a 15-25 gallon sump/refuge. My skimmer has begun filling up very quickly with greenish water. Before, when I had fish in the tank the water would take 4-7 days to fill up and would be a sludge. This water fills up the collection cup in about 24hours and looks like green tea.

What could be the cause?
